Koh Mook Travel Guide: 8 Best Things to Do

A Thai island like Thailand used to be

It unfortunately took us countless trips to Thailand before Koh Mook finally made it onto an itinerary.

When it did, the small island became the first beach stop on a long Andaman island-hop all the way to Phuket, with Koh Kradan, Koh Ngai, Koh Lanta and several more to follow.

We came in from Laos in mid-January 2026 and stayed on Koh Mook for a week, travelling as a family of four (Alex, Victoria, Adrian at 2.5 and baby Zoe at 6 months), along with Victoria’s mother.

Koh Mook doesn’t have the most beautiful beaches in the Andaman, or the best restaurants, or the fanciest resorts. It’s not the cleanest island, the most laid-back or the most interesting for hiking or wildlife…

But, and it’s a big but, Koh Mook strikes a lovely balance between all of the above.

For many travellers, what’s on offer here is exactly what you want from a Thai holiday:

Koh Mook is walkable.
The beaches offer plenty of space even in the busy high season.
Accommodation prices are very reasonable.
It’s a perfect base for boat tours to much smaller (and more expensive) islands like Koh Kradan and Koh Ngai.

There are no big chains on Koh Mook and no 7-Elevens (a rarity in Thailand in 2026).

Instead, there’s plenty of authentic island life going on a few metres behind the tourist stretch, including the kids who still wave at visitors on their way home from the island’s one school.

Koh Mook is simply a safe place to holiday. Children will love it here, and we found the locals to be delightfully warm with them.

From the moment we stepped off the boat, we totally fell for this little island.

So if you’re wondering what to do on Koh Mook, how to get there, when to go and much more, this Koh Mook guide covers it all.

Where to stay on Koh Mook:

Budget: Kohmook Happy Time Bungalow – Where we stayed ourselves. A sweet family-run spot with some of the best-value family rooms on the island.
Value for money: Koh Mook Garden Beach Resort – The island’s original resort, with a fantastic pool, lovely staff and a secluded setting on the village side.
Value for money: Mookies Bungalows – A peaceful little hideaway near Charlie Beach with cosy bungalows, lots of greenery and famously warm hosts.
Luxury: Koh Mook Sivalai Beach Resort – The iconic sand spit resort with squeaky sand on both sides. The best resort on Koh Mook.

Why visit Koh Mook

The island feels like Thailand used to feel before the bigger destinations got built up. On Koh Mook, you’ll find no high-rise resorts and no 7-Elevens.

Instead, there’s a small fishing village, a good selection of family-run guesthouses and two lovely main beaches on opposite sides of the island.

Day-to-day life here is slow.

And because everything is walkable, you quickly start to recognise faces like the woman at breakfast, the family running your hotel and the kids cycling home from the island’s one school.

Koh Mook doesn’t show up on every Thailand itinerary, and you won’t bump into big tour groups or day trippers here.

Koh Mook is also a great base for some of the prettiest day trips in the Andaman, including the famous Emerald Cave just a short boat trip away.

Besides, the mainland is only 15-20 minutes away by longtail boat, so it’s simple to reach, even in the shoulder season.

Where is Koh Mook?

Koh Mook, also written Ko Mook, Ko Muk or Koh Muk, is in Trang in southern Thailand – part of a cluster of islands that includes Koh Kradan, Koh Ngai and Koh Libong.

It’s a small island. Or, at least the developed part is quite compact.

The village takes about 15 minutes to walk end to end, and well-paved lanes connect the whole place.

Koh Mook is part of Hat Chao Mai National Park, which covers a stretch of the Trang coastline and several of its islands. The famous Emerald Cave is inside the park too.

The best things to do on Koh Mook

You won’t run out of things to do on Koh Mook, but you also won’t feel pressured to tick them all off.

Here’s what we’d put on the list of what to do on Koh Mook:

Sivalai Beach – The iconic sand spit
Emerald Cave – Swim into a hidden lagoon
Charlie Beach – Sunset on the west side
A day on the water – Snorkel and island-hop by longtail
Spot a hornbill (and maybe a dugong) – Wildlife on the island
Get a Thai massage – With a view of the water
Walk or scooter the lanes – The slow way to see the island
Sabai Beach and the viewpoint – For the more adventurous

1. Sivalai Beach – The iconic sand spit

Koh Mook’s most famous view is the long white sand spit on the eastern side of the island.

That’s Sivalai Beach, more properly called Hua Laem Prao Beach, and it really is as pretty as it looks.

The land here mostly belongs to Sivalai Beach Resort (adlink), but the spit itself is open to anyone, and you can walk here freely.

The water by the spit is also the deepest on the island, so it’s the best place for an actual swim rather than a paddle, even at low tide.

We visited the beach for sunset and had dinner at the Sivalai restaurant.

While the service was friendly and the food was good, the prices were (unsurprisingly) a bit higher than elsewhere on Koh Mook.

The setting makes it worth it though, even if you just come for a drink at sunset.

2. Emerald Cave – Swim into a hidden lagoon

The Emerald Cave (Tham Morakot) is Koh Mook’s second claim to fame (besides the sand spit).

You reach it by boat. The entrance is a small opening in the cliff face on the western side of the island.

From there, you swim about 80 metres through a dark tunnel before emerging onto a hidden beach surrounded by sheer limestone walls open to the sky. It’s spectacular.

We did the trip to Emerald Cave back in 2018 on a “four islands” tour from Koh Lanta and didn’t repeat it this time, as the swim isn’t really doable with a 6-month-old.

However, it’s deservedly one of the most popular things to do in this part of Thailand. At peak hours, it can be heaving with tour groups arriving from Koh Lanta and Krabi mid-morning.

So, if you can, go early or late by arranging a private longtail from the village.

Renting a kayak is another option for the more adventurous and means you can avoid the crowds entirely.

Important: The cave is usually not accessible at high tide, so check tide times before you go. Mid-tide is best, as there’s still a proper beach on the other side. We often use Tideking for this.

Also, bring a waterproof torch if you go independently!

3. Charlie Beach – Sunset on the west side

Charlie Beach (also called Haad Farang, Farang Beach or Garnet Beach) is on the western side of Koh Mook, about a 30-minute walk from the village or, more conveniently, a 50-baht tuk-tuk ride per adult (~ 1.3 EUR / 1.5 USD).

Here you’ll find a row of small beach restaurants and bars set back under the trees, soft sand and an often clear view across the channel to Koh Kradan.

We came over to Charlie Beach in the late afternoon for sunset and found plenty of shade, a couple of low-key reggae bars and a lovely end-of-day calm.

This is a really chill place.

A handful of small bungalow operations, including the very well-reviewed Mookies Bungalows (adlink), are tucked behind the beach. Charlie Beach is a good area to base yourself if you want a quieter stay than the village side.

Getting back to the village is no hassle. Tuk-tuks line up to take people home after sunset, and the price is still a flat 50 baht per adult, as it is for all other trips around the island.

4. A day on the water – Snorkel and island-hop by longtail

Organising a day on the water from Koh Mook is super simple.

Every guesthouse, restaurant and tuk-tuk driver can put you in touch with someone, and prices are fair.

Most “four islands” or “five islands” day tours include Koh Kradan (great snorkelling), Koh Chueak, Koh Maa and the Emerald Cave, with lunch and gear usually provided.

Koh Ngai is worth stopping at, too.

You can also book a private longtail for a half or full day, which is what we’d recommend if you’re travelling with kids or just want to set your own pace.

5. Spot a hornbill (and maybe a dugong) – Wildlife on the island

Two of Koh Mook’s wildlife claims to fame are hornbills and dugongs.

The hornbills are the easier of the two to find. We spotted one perched in a tree near our hotel one morning, which got Adrian very excited.

They’re large, unmistakable with their huge beaks, and pretty active in the forested parts of the island.

Dugongs are rarer.

The seagrass beds around the Trang islands are some of the best dugong habitat in Thailand, and in good years, dugongs are sighted regularly. Occasionally even close to the main pier on Koh Mook.

We kept an eye out and didn’t see one, which is unfortunately the more common outcome.

If actually seeing one matters to you, dedicated dugong-spotting boat tours improve your odds considerably. Koh Libong, just south, is reportedly the better base for that.

6. Get a Thai massage – With a view of the water

One of the best things to do on Koh Mook, and in Thailand in general, is getting a massage.

Massage on Koh Mook is excellent value, with prices fairly consistent across the island at around 400-500 baht (~ 10-13 EUR / 12-15 USD) for an hour of Thai massage in 2026.

Alex tried Family Health Massage, a short walk from our hotel Happy Time (adlink).

The reviews flagged it as the best on the island, and that turned out to be plausibly accurate, with a calm setting, a view of the water and a proper, no-shortcuts massage.

There are naturally several other spots dotted around the village if that one’s full.

7. Walk or scooter the lanes – The slow way to see the island

A handful of well-paved lanes connect all parts of the village and the communities in between, and just wandering them is one of the better things to do on Koh Mook.

You’ll pass the school, the occasional dog in the shade and lots of everyday life.

We can especially recommend walking past Happy Time to do a loop in the southwesternmost part of the village, where the ratio between tourists and locals quickly flips.

If you’d rather cover more ground, scooter rental costs about 250 baht (~ 6.5 EUR / 7.7 USD) per day in 2026, and bicycles are available as well.

Bonus tip: The paved lanes with all their mini-bumps also happen to be perfect for stroller naps. Don’t underestimate this one if you’re travelling with a toddler.

8. Sabai Beach and the viewpoint – For the more adventurous

On the western part of the island, there’s a small beach called Sabai Beach and a separate viewpoint, both reached on foot through the forest.

We didn’t make it over there ourselves this time. With Zoe still tiny, we kept things mostly close to base.

From what we read, though, the path can be buggy (bring repellent), and the beach has had some debris issues, although the view out to sea is reportedly lovely.

If you do go, take water and bug spray, and ideally set off in the morning before it gets too hot.

How many days to spend on Koh Mook

If you’re still figuring out how long to spend on Koh Mook, three to five nights is enough for most travellers.

We stayed six nights, and although it was a touch on the long side for the island alone, it suited us well as a recovery stop after a stretch of travel and as a starting point for Koh Kradan and Koh Ngai.

If Koh Mook is one of several stops on a longer island-hop, three nights gives you time to see both sides of the island, do a boat trip and still have a proper lazy day.

If you’re after a real slowdown and a great base for exploring the southern Andaman Sea, a week passes very easily here too.

Where to stay on Koh Mook

The island is roughly split into two areas to stay in.

The village side on the east is where most people base themselves.

It’s where the boats arrive, where most of the restaurants are and where Sivalai Beach is.

It’s easier with kids, and there’s more life in the evenings.

The Charlie Beach side on the west is quieter and a little more castaway. It’s a short tuk-tuk hop from the village, or a 30-minute walk if you’d rather, so it’s easy to get between the two.

We’ve put the hotels we’d recommend below, mostly on the village side, with one great option at Charlie Beach for those who want the quieter feel.

For full descriptions of each of these hotels, photos from inside the properties, more on the Charlie Beach side, what you should know about the accommodation market on Koh Mook before booking, and a couple more things to consider when picking where to sleep, head over to our dedicated where to stay on Koh Mook guide.

Where to Stay on Koh Mook: Best Hotels & Areas

Our recommendations for the best places to stay, from budget bungalows to the island’s iconic luxury resort

Where we stayed: Kohmook Happy Time Bungalow

Happy Time was our base for the week we stayed on Koh Mook, and we would recommend it without hesitation as a budget pick, particularly for families.

The family bungalow was one of the cheaper options we could find that comfortably fit the four of us. There are also smaller ones for solo travellers and couples.

What we loved most was that the family running it could not have been kinder.

They looked after us from the day we arrived, sorting transfers, helping with the kids and suggesting places to eat. They also run the small restaurant next door.

Happy Time isn’t on the beach, but the beach is only a few hundred metres’ walk, and the same goes for the main strip of shops and restaurants.

See prices and availability at Kohmook Happy Time Bungalow here (adlink).

Where to eat on Koh Mook

The eating scene on Koh Mook is small but pleasingly varied. Here are a few places we returned to during our stay.

Miss Island Bakery

We had breakfast here every single day during our stay.

The menu is huge, covering smoothie bowls, pancakes, waffles, sandwiches, burgers, Mexican, Middle Eastern, Italian and a full Thai menu.

There are plenty of vegan and vegetarian options, and the prices are fair.

Sugar’s

A small, family-run place right on the water on the village side, with lovely Thai curries and one of the prettiest spots to eat lunch on the island.

Sea Beach Restaurant

Sea Beach Restaurant was our “local restaurant” right next to Happy Time (adlink), where we stayed.

While the food isn’t the most exciting on the island, it’s solid, the prices are fair, the service is lovely, and the view is great.

Sivalai Restaurant

Pricier than elsewhere on the island, but the setting at sunset is unbeatable, and the food and service backed it up.

We think the restaurant at Sivalai Beach Resort (adlink) is worth visiting at least once during your stay.

Koh Mook Garden Beach Resort

We ate full meals here on both of our visits and loved it. The food was great, the staff sweet and the setting full of birdsong and tall trees.

Apart from the food, we can recommend visiting for the huge pool with a slide (a big hit with Adrian), as well as the covered playground.

Did we mention the staff are exceptionally great with kids?

Alcohol on Koh Mook

If you’re looking for a cold beer with dinner, Koh Mook can be a little surprising.

The island is home to a predominantly Muslim community, and many local restaurants and shops do not sell alcohol as a result.

While some resorts and places aimed at visitors may serve beer or cocktails, alcohol is generally much less visible and less widely available than on islands such as Koh Lanta or Koh Lipe.

For us, that’s part of the island’s charm, but it’s worth knowing before you go.

How to get around Koh Mook

Tuk-tuk

The island’s main mode of transport is a scooter with a sidecar, and there are loads of them.

Prices are fixed at 50 baht per adult per ride (~ 1.3 EUR / 1.5 USD) in 2026, regardless of where you’re going. No haggling needed.

Drivers will fit luggage in too, although a family with a lot of bags will sometimes need two tuk-tuks as we did on the way in from the pier.

Sign saying a tuk-tuk "taxi" is 50 baht on Koh Mook, next to a tuk-tuk by the pier — When we visited Koh Mook in 2026, all tuk-tuk rides were a flat 50 baht per adult, no matter where you’re going.

Walking

The village side is walkable end to end in about 15 minutes. Very small, in other words, with most things within a 5-minute walk.

Charlie Beach is technically reachable on foot in about 30 minutes from the main village, but the road isn’t very walking-friendly, so we wouldn’t generally recommend it.

Scooter

Scooter rentals cost about 250 baht per day (~ 6.5 EUR / 7.7 USD) in 2026 and are easy to organise through any hotel or elsewhere around the village.

A scooter is mostly useful if you want to get to Charlie Beach for sunset on your own clock or simply get around very quickly.

Scooter rental on Koh Mook — Although most people probably won’t need their own wheels, it’s quite easy to rent a scooter on Koh Mook.

Bicycle

Several places rent bikes, too, if you’re not in a rush.

Longtail boat

For anything off-island (Emerald Cave, Koh Kradan, snorkelling spots or the like), you’ll be on a longtail.

They’re easy to arrange through your hotel or any of the operators in the village.

Longtail boats are the main way to get around Koh Mook by sea.

How to get to and from Koh Mook

From Trang (the closest mainland hub)

The shortest crossing to Koh Mook is from Kuan Tung Ku Pier (also written Khuan Tung Ku), about 45 minutes south of Trang town. The longtail crossing takes around 15-20 minutes.

Many people buy a combo ticket (minivan from Trang plus the boat) for 250 baht* per adult (~ 6.5 EUR / 7.7 USD).

We arranged ours through our hotel in Trang, and the whole transfer took a little more than an hour by van plus the boat.

If you turn up at the pier independently, a longtail to Koh Mook is also likely to cost around 250 baht per adult (~ 6.5 EUR / 7.7 USD), with the boat leaving when it’s more or less full, or about 1,800 baht* (~ 48 EUR / 55 USD) to charter the whole boat for your own party.

There’s also a cheaper scheduled local ferry, but it only runs once or twice a day.

Hat Yao Pier is another option slightly further south along the coast, closer to Koh Libong.

*Prices are from 2026.

From Trang Airport

Many visitors reach Koh Mook by flying into Trang Airport.

From there, you can either spend a night in Trang (as we did) or continue directly to the pier and catch a boat to the island.

Trang Airport is about an hour from either Kuan Tung Ku Pier or Hat Yao Pier.

Ticket booths inside the terminal sell minivan-and-boat combos to Koh Mook, or you can pre-book your trip on 12Go (adlink).

From Krabi, Koh Lanta, Phi Phi or Phuket

In high season (roughly mid-October to April), speedboats run from all the usual Andaman islands, Krabi and Phuket down through Koh Mook on their way to Koh Lipe.

Booking through 12Go (adlink) is the easiest way to see schedules and reserve a seat.

To Koh Kradan

From Koh Mook we went directly to Koh Kradan, and the crossing was easy.

A private longtail from Koh Mook to Koh Kradan cost us 1,000 baht* (~ 27 EUR / 30 USD), including pickup from our hotel to the pier. We expect the price to be similar going the other way.

A shared boat usually costs around 250 baht per adult (~ 6.5 EUR / 7.7 USD)*.

Speedboats are also available if you want the trip to be even quicker.

*Prices are from 2026.

Which option should you choose?

If you’re already on the Andaman circuit, the speedboat is the easiest.

If you’re flying into Trang or coming up from further south, the crossing from Kuan Tung Ku Pier is the cheapest and shortest.

Remember: If you’re nervous about boats or visiting outside the dry season, it helps that Koh Mook is so near the mainland.

When to visit Koh Mook

Seasons and weather

Koh Mook has a warm, tropical climate year-round, with temperatures usually somewhere between 24°C and 32°C (75-90°F).

Like the rest of the Andaman coast, the island has three main seasons: the cool dry season (the high season), the hot season and the rainy season.

That said, weather patterns can vary from year to year, so having a bit of flexibility is always good.

What is the best time of year to visit Koh Mook?

The best time to visit Koh Mook is generally from December to February, with cooler temperatures, plenty of sunshine and calm seas.

November is also a great time to travel, with slightly lower prices compared to the peak weeks of December and January.

November to February (Koh Mook’s high season)

We visited Koh Mook in January 2026, and the weather was about as good as we’ve experienced in Thailand.

This is Koh Mook’s high season, with the most tourists and the most stable sunny weather.

Temperatures are slightly cooler, and hotel prices are higher, especially from around mid-December to mid-January.

If you’re planning to travel to Koh Mook over Christmas or New Year, we strongly recommend that you book accommodation well in advance.

March to May (the hottest months)

Koh Mook generally sees the highest temperatures from March to May, with rainfall starting to pick up towards the end of this period.

If you’re planning to visit in March, April or May, it might be worth paying extra for a room with air conditioning and access to a pool.

June to August (the start of the rainy season)

From June (or sometimes as early as May), the heat begins to subside as the southwest monsoon brings heavier rainfall to the Andaman coast.

The rain usually falls in intense showers and rarely lasts all day, so there are still plenty of sunny hours.

In July and August, Koh Mook is at its greenest, and accommodation prices drop significantly.

The sea also starts to feel different in these months. The water becomes less clear, and the calm, glassy conditions of high season give way to bigger swells on some days.

September and October (the wettest months)

September and October are the wettest months on Koh Mook, with frequent heavy rain.

The sea can be noticeably rougher and murkier, and boat trips and swimming aren’t always possible during this time.

The rainfall can be so intense that the roads almost turn into rivers. It’s wise to be prepared with an umbrella and a good book if you find yourself needing to stay sheltered for a while.

Many smaller places close in the low season. From around May to October, Koh Mook becomes extremely quiet and a large number of bungalow operations, restaurants and smaller hotels either close completely or scale back significantly.

A handful of larger resorts and locally run guesthouses continue operating year-round, but places to stay become much more limited, and some facilities may run at reduced capacity.

Koh Mook’s short mainland crossing (only 15-20 minutes by longtail from Kuan Tung Ku Pier) also means the island generally stays more reachable than the outer Trang islands when the weather turns, though crossings can still be limited on the roughest days.

Where to go after Koh Mook

Koh Mook makes a natural first stop on a longer Andaman island-hop, and the nearby islands are some of the prettiest in this part of Thailand.

Heading north, the closest stops are Koh Kradan and Koh Ngai, both reachable by longtail or speedboat in well under an hour.

We went straight to Koh Kradan from Koh Mook, and it’s a true stunner – much smaller, quieter and with one of Thailand’s most spectacular beaches.

Koh Ngai is a touch further out from Koh Mook and is a bit more happening. The beach here is also A+.

Further north, Koh Lanta is a good next stop if you want a bigger island, with proper long beaches, more variety in food and a Koh Mook-like easy pace despite the larger size.

Heading south, Koh Libong is the closest neighbour and the better base if dugong-spotting is high on your list.

Koh Lipe lies much further down the chain but is still reachable by speedboat in high season.

Compared with Koh Mook, Koh Lipe has more action and beaches that really do compete with the best of the best.

Tips for visiting Koh Mook

Koh Mook is a beautiful island. Make sure to bring a good camera! Here’s our guide to lightweight photography gear for high-quality travel content.
Book accommodation well in advance if you’re travelling in December or January. Koh Mook is small, and the better places fill up months ahead of time.
Bring enough cash for your stay. There’s just one ATM as far as we know, and many smaller restaurants and tuk-tuk drivers are cash only.
Wifi is widely available in hotels and most cafés. If you need data elsewhere, consider an eSIM. We’ve previously used Airalo (adlink) with great success.
The electrical outlets on Koh Mook, as elsewhere in Thailand, are commonly combination sockets. They often take both two-pin Type A plugs with flat prongs and Type C plugs with round pins. Grounded Type O outlets also occur, so you may need an adapter. The standard voltage is 220 volts.
Bring your own water bottle and refill it at cafés, restaurants or water dispensers.
The sun is strong. Remember sun protection and stay in the shade during the hottest hours in the middle of the day.
Mosquito repellent is worth packing. Mosquitoes aren’t too bad in the village, but they’re more common in the wooded parts and around dusk.
Don’t try to do the Emerald Cave at high tide. Check the tides before going here.
Beachwear belongs on the beach. As elsewhere in Thailand, it’s considered rude to wear a swimsuit when you’re not on the beach, especially when walking through the village.
A waterproof phone pouch is useful for both boat trips and the Emerald Cave swim if you do it.
Koh Mook is very family-friendly. Thais are fond of children, and we found the locals here particularly warm with them.
Don’t flush toilet paper. Put paper in the provided bin instead.
Remember travel insurance. We compare the best travel insurance for digital nomads and long-term travellers here.

FAQ about Koh Mook

This Koh Mook travel guide is long.

Here are short answers to some of the most frequently asked questions about the island.

Is Koh Mook worth visiting?

If you’re looking for a quieter, more authentic side of Thailand without huge resorts or busy nightlife, then yes!

Koh Mook has two lovely main beaches, a super-friendly local community and easy access to the famous Emerald Cave.

We loved our six nights there and would happily go back.

Is Koh Mook good for families?

Very much so. The island is small and walkable, the lanes are paved (perfect for strollers), the locals are warm with children, and the overall pace is slow.

We visited with a 2.5-year-old and a 6-month-old and found it one of the easiest Thai islands we’ve travelled to with kids.

There’s no big-city traffic to worry about, and most hotels and restaurants are used to welcoming families.

How many days do you need on Koh Mook?

Three to five nights is enough for most travellers to see the main beaches, do a boat trip and enjoy some real downtime.

A week works well if you want to settle into the island’s slower pace or want to use Koh Mook as a base for day trips to the surrounding islands.

How do you pronounce Koh Mook?

Roughly “koh mook”, with “mook” rhyming loosely with “book”. In Thai, “koh” simply means island.

You’ll sometimes see the name written as Ko Mook, Ko Muk or Koh Muk, but the pronunciation is essentially the same.

Is it easy to island-hop from Koh Mook?

Yes. Koh Kradan and Koh Ngai are within easy reach by longtail or speedboat, and both are well worth an overnight stay.

During the high season, Koh Mook is also connected by speedboat routes to islands like Koh Libong, Koh Lanta, Phi Phi and Koh Lipe, along with mainland hubs such as Krabi and Phuket.

What is there to do on Koh Mook besides the beach?

Not a lot, but more than you might expect.

The Emerald Cave swim is spectacular, snorkelling and island-hopping tours run daily, and the village itself is worth wandering for an afternoon.

Sunset at Charlie Beach is a must, too.

You can also hire a longtail to explore the smaller surrounding islands, get a massage with a sea view or tackle longer walks like the hike to Sabai Beach.

Can Koh Mook be visited in the rainy season?

Yes. Unlike neighbouring Koh Kradan or Koh Ngai, which completely shut down in the rainy season, Koh Mook remains inhabited year-round thanks to its local fishing village.

However, tourist options thin out considerably. From around June to October, direct speedboat transfers largely stop running (meaning you’ll most likely arrive by ferry or private boat from the Trang mainland), and a good number of the smaller bungalow operations and beachfront bars close entirely.

Thankfully, the island’s nicest resort, Koh Mook Sivalai Beach Resort (adlink), stays open year-round as far as we can tell.
