Why is Koh Samui so famous?
You step off the plane into an open-air terminal, and within the hour you are in your own pool above the Gulf. That is Koh Samui. It is famous for palm-lined beaches, a calm Gulf of Thailand sea, hillside pool villas and some of Asia's best wellness resorts. The Department of Marine and Coastal Resources measures it at about 236 km², one of Thailand's largest islands. It became world famous again when The White Lotus filmed its third season here.
Four Seasons confirmed in a February 2025 press release that the season used Four Seasons Resort Koh Samui as its main setting. HBO's own location notes add Anantara Lawana and Anantara Bophut on Samui, and two resorts in Phuket.
Away from the screen, Samui feels quieter and greener than Phuket. A ring road circles the island, with beaches on every side and coconut groves and jungle hills in the middle.
Koh Phangan, Koh Tao and the Ang Thong Marine Park are all within reach by private boat. That makes Samui a strong base for a week of sea and island days.
For you, the appeal is privacy and ease. The island runs at a calm, unhurried pace that rewards a stay of a week or more.
Which months suit Koh Samui best?
The best time to visit Koh Samui is February to April, the driest stretch of the year. Thai Meteorological Department normals show February with about 64 mm of rain. October to December is the wet season, and November is the wettest month at about 445 mm. If you must avoid one month, avoid November.
This pattern is the reverse of the Andaman coast. Phuket and Krabi are driest from December to March and wettest in September. Samui stays fairly dry from May to September, when the west coast has its monsoon.
January is still fairly wet after the north-east monsoon, with about 127 mm on average, but sunny days are common. December has short heavy showers and rough seas on the east coast. Late in the year, boat trips can be cancelled when the wind is strong.
One event to plan around: the 24th Samui Regatta runs from 22 to 29 May 2027 off Chaweng. Samui's numbers are set against every other region in our Thailand weather guide.
For rain, sea and crowds month by month, see our guide to the best time to visit Koh Samui.
Which part of Koh Samui should you stay in?
Stay in Choeng Mon or Bophut for calm bays close to the airport, or Chaweng for restaurants and nightlife. Maenam has long quiet sand, and the west coast has sunsets and space. Lamai and the south suit a slower stay. Every area is linked by the ring road, so you can explore by car.
Chaweng. The island's longest and busiest beach, on the east coast, with resorts, shops, beach clubs and the late nightlife. Read our Chaweng guide.
Choeng Mon. A small, curved bay in the north-east with several top resorts and calm water. See the Choeng Mon guide.
Bophut and Fisherman's Village. The north coast's old fishing village has wooden shophouses, good restaurants and a relaxed beach. Best for couples who like to walk out to dinner. Read the Bophut guide.
Maenam. A long, peaceful beach on the north coast with views across to Koh Phangan. Best for families and long stays. See our Maenam guide.
Lamai. The second big east-coast beach, about 4 km long according to the Department of Tourism. It is calmer than Chaweng, with a local feel. Read the Lamai guide.
Laem Set and the south. Rocky coves and quiet resorts on the southern tip. Best for privacy and wellness stays.
Lipa Noi and Taling Ngam. The quiet west coast, with shallow water and the island's best sunsets over the Ang Thong islands. Best for families and villa groups. See the Lipa Noi guide.
The north-east tip, near the Big Buddha and Wat Plai Laem, also has small resort bays. Read our Plai Laem guide.
For each beach by type and season, see our guide to Koh Samui beaches.
Where are the best luxury resorts on Koh Samui?
The best luxury resorts on Koh Samui are Four Seasons Resort Koh Samui, Banyan Tree Samui, Six Senses Samui, Conrad Koh Samui and Vana Belle. W Koh Samui, Belmond Napasai, Kimpton Kitalay and Cape Fahn add strong choices. Most offer pool villas, so the decision is about setting, style and beach.
Four Seasons Resort Koh Samui, north-west coast. Pool villas on a coconut-covered hillside above a private bay. This is the resort from The White Lotus. Its breakfast restaurant is open to outside guests by reservation, the resort says.
Banyan Tree Samui, Lamai side. Pool villas stepped down a hill to a private cove, with a large spa. It is on the MICHELIN Guide's two-Key list for 2026.
Six Senses Samui, northern tip. Villas on a headland with wide sea views and a strong wellness focus. We confirm opening dates for your stay when we book.
Conrad Koh Samui, south-west coast. Hillside pool villas facing the sunset. Hilton lists it 28 km from the airport, so book it when you want true seclusion.
Vana Belle, Chaweng Noi. Marriott lists 79 pool suites and pool villas, each with a private pool, above a quiet bay.
W Koh Samui, Belmond Napasai and Kimpton Kitalay. W is lively and modern on the north coast. Belmond Napasai is calm and classic on Maenam's western end. Kimpton Kitalay is a family-friendly beach resort on Choeng Mon bay.
Cape Fahn and Anantara Lawana. Cape Fahn is an all-villa hotel on a private islet off Choeng Mon. Anantara Lawana, in Chaweng, has 122 rooms, suites and villas and holds one MICHELIN Key, according to Anantara.
On a first visit, a pool villa at a resort gives you privacy and full service at once.
InterContinental Koh Samui is closed for refurbishment and expects to reopen by the end of 2027, so we do not book it for now. For the full shortlist by beach, see where to stay on Koh Samui.
Should you rent a private villa on Koh Samui?
Rent a private villa on Koh Samui if you are a family or a group of six or more. Samui is one of Asia's best villa islands. A hillside villa gives you a private pool, a sea view, a chef and a housekeeper. It often costs less per person than several resort suites.
A typical choice is a 6-bedroom villa above Choeng Mon with an infinity pool. Or choose a beachfront villa on the quiet west coast, for sunsets and shallow water for children. Many come with a villa manager who arranges drivers, boats and in-villa massage.
Check three things before you book: the road up to the villa, the walk to the beach and the bed layout. Under the 2023 Hotel Act regulation, a rental with up to 8 rooms and 30 guests that is notified and certified is not a hotel. Larger rentals need a hotel licence. We only book villas that meet this rule.
Villas are paid in full at booking, with no cancellation, so we check every detail first. We visit every villa we recommend and stock it before you land. One planner books the villa, chef, boat and driver as one plan, for any group size, with Samui staff who run every transfer. If a villa looks better online than it is, we tell you. See our luxury villas on Koh Samui.
Is Koh Samui good for a wellness retreat?
Yes. Koh Samui is one of Asia's leading wellness islands. Kamalaya, on the south coast, is the best-known retreat, with Absolute Sanctuary, Samahita and Vikasa for yoga and fitness. Most programmes run for five to fourteen nights, with a consultation, daily treatments, healthy food and movement classes.
A seven-night programme usually starts with a health check and a talk with a wellness adviser. Each day brings one or two treatments, such as massage, a herbal steam or a body wrap, plus yoga, pilates or a guided hike.
Retreats differ in their approach. Some are calm and spa-led, others are about fitness and weight loss, and some focus on meditation and sleep. Tell us your goal and we match you to the right place and the right length of stay.
February to April is the best time for a retreat, with dry days for outdoor classes. See our wellness retreats on Koh Samui.
What can you do on the water around Koh Samui?
The best water day from Koh Samui is a private boat to the Ang Thong Marine Park. It is a group of limestone islands with a hidden green lagoon. The park is closed from 1 November to 15 December 2026. Koh Phangan's quiet bays and the reefs of Koh Tao are also easy days by private yacht.
Ang Thong Marine Park. The Tourism Authority of Thailand lists a special fee of ฿300 for a foreign adult at Ang Thong. Read our Ang Thong guide.
Koh Phangan and Koh Tao. Phangan's north-coast bays are quiet and beautiful by day. Koh Tao has clear water for snorkelling and diving, and a fast boat makes both easy day trips.
Your boat leaves at 08:30, before the tour boats. By late morning you are swimming off a quiet beach. The sea is calmest from February to September on this coast, and rougher from October to December.
A boat with more than 12 passengers counts as a passenger vessel under the Navigation in Thai Waters Act. In the parks, boats use mooring buoys and never anchor on coral. See yacht charter on Koh Samui.
One safety note. The Department of Marine and Coastal Resources warns of box jellyfish around Samui and Phangan, mainly in the south-west monsoon. Hotels and beach restaurants keep vinegar for first aid. Swim at beaches with nets or lifeguards, and call 1669 in an emergency.
Which island days and sights come first?
The top things to do on Koh Samui are the Big Buddha and Wat Plai Laem and a walk through Fisherman's Village. Add the Hin Ta and Hin Yai rocks at Lamai, an ethical elephant sanctuary, golf and a cooking class. Add a sunset dinner on the west coast and a day on the water.
Big Buddha and Wat Plai Laem. A large golden Buddha sits on a small island in the north-east, joined by a causeway. Nearby, Wat Plai Laem has colourful statues on a lake. Cover your shoulders and knees at both.
Fisherman's Village, Bophut. Old Chinese wooden shophouses now hold restaurants, galleries and small shops. Go in the late afternoon and stay for dinner by the sea.
Hin Ta and Hin Yai. The Tourism Authority of Thailand places these famous rock formations at Lamai bay. A short stop on a drive around the island.
An ethical elephant sanctuary. Samui Elephant Sanctuary has two sites, in Bophut and Chaweng Noi, and offers no riding. Its site lists ฿3,000 for an adult on the three-hour half-day programme. See elephant sanctuaries in Thailand.
Golf. Santiburi Samui Country Club is the island's main course, in the hills above Maenam. Its 2026 early-bird rate for 18 holes is ฿3,550, including cart and caddie. See golf on Koh Samui.
A cooking class. Learn southern Thai curries with a chef in your villa, or join a class at your resort after a morning market visit.
Temples and viewpoints are best before 10:00, and the beach and spa fill the middle of the day. The west coast is the place to be at sunset. A driver for the day makes it easy to combine three or four stops without rushing.
See our shortlist of the best things to do in Koh Samui. It covers the island and the sea, with the best time for each.
What is Koh Samui like at night?
Koh Samui at night is relaxed and stylish, with sunset beach clubs, resort bars and clubs in Chaweng. Licensed entertainment venues on Koh Samui, and licensed venues inside hotels, may stay open until 04:00 under a 2023 ministerial regulation. Start with a long dinner, move to a beach club and finish in Chaweng in the early hours.
Start at sunset on the west coast or at a beach club on the north or east coast. ARKbar Beach Club on Chaweng Beach is the best known. Then move to dinner at your resort or in Fisherman's Village. Chaweng has the late clubs and bars. Club Seen in Chaweng is closed for renovation, with no reopening date.
For a special night, we arrange a private dinner on the beach, or a chef and a band at your villa. A sunset cruise with drinks on deck is the other classic. For a birthday or a wedding, host a villa party for up to about 30 guests, where the music and the guest list are yours.
No restaurant on Samui holds a MICHELIN star in the 2026 guide, but many resort kitchens cook to a very high level. The 2027 selection is announced on 10 November 2026.
Carry your passport, as clubs check ID and the legal age is 20. We arrange a car and driver for the evening. See our Koh Samui nightlife guide.
Should you choose Samui or Phuket?
Choose Koh Samui for a calmer, villa-led stay and the Gulf islands. Choose Phuket for more resorts, more international flights, bigger nightlife and Phang Nga Bay. The seasons are opposite: Samui is driest from February to April, Phuket from December to March. In July and August, Samui is usually the better choice.
Phuket is larger and busier, with a real town and more choice at every level. Both have excellent villas and yachts.
You can do both. Bangkok Airways links the two islands, so you can split a long stay by season. Read the full comparison in Phuket vs Koh Samui.
How do you get to Koh Samui?
The usual route is a flight to Samui Airport (USM) from Bangkok Suvarnabhumi. Bangkok Airways gives about 1 hour 10 to 20 minutes for the flight. The airport is owned and run by Bangkok Airways, which is why fares are often higher than on other domestic routes. Bangkok Airways also flies from Chiang Mai.
The airport is open from 06:00 to 22:00, according to the Civil Aviation Authority of Thailand. Bangkok Airways asks passengers to be at check-in at least 1 hour 30 minutes before domestic flights and 2 hours before international ones.
If you fly in from abroad, you clear immigration at your first Thai airport, usually Bangkok. File the free Thailand Digital Arrival Card within 3 days before you land; our arrival card guide shows you how. Bangkok Airways also has non-stop flights to Samui from Singapore and Hong Kong.
A private jet can land at Samui within the airport's hours, with permission and a slot. Seaplane flights are not licensed in Thailand today, so we do not offer them; see seaplane travel for the latest.
The other way is to fly to Surat Thani and take a car ferry from Don Sak pier. Read Bangkok to Koh Samui.
On arrival, we meet you at the open-air terminal and drive you to your villa. For health, Bangkok Hospital Samui is in Chaweng, and a branch, Phangan International Hospital, serves Koh Phangan.
Which islands can you visit from Koh Samui?
From Koh Samui you can visit Koh Phangan, Koh Tao and the Ang Thong Marine Park. Phangan is closest, a short boat ride north. Koh Tao is further but easy by fast boat. Ang Thong lies to the west and is best as a full private day.
Koh Phangan. Quiet bays, wellness and the Full Moon Party. See Koh Phangan and Koh Samui to Koh Phangan.
Koh Tao. Clear water and some of Thailand's best diving. See Koh Tao and Koh Samui to Koh Tao.
Ang Thong. A group of limestone islands and a green lagoon, open again from 16 December 2026.
Example plan. Five days on Koh Samui. Day one: a car meets you at the open-air terminal. By lunch you are in a hillside pool villa, from ฿18,500 a day, VAT included. Day two: the Big Buddha and Wat Plai Laem before 10:00, then dinner in Fisherman's Village. Day three: a private boat to Ang Thong, with the viewpoint climb and lunch on board. Day four: a slow spa day, then sunset on the west coast. Day five: a speedboat to Koh Phangan's quiet north-coast bays.
