Because it delivers the full Thai-island experience with less friction than most: an international airport, so no boat transfers; a varied coastline holding both a lively resort strip and quiet private bays; and a deep bench of villas and resorts. It suits honeymooners, families and groups equally, and pairs easily with Bangkok or the quieter neighbouring islands.

When is the best time to visit Koh Samui?

Roughly December to August, the opposite of Thailand's Andaman coast, with the driest, sunniest weather in the middle of the year when Phuket is under cloud. October to December is the wet season, with heavier rain and rougher seas. January to April brings the finest weather and the highest prices; mid-year offers reliable sun and better value.

Which is the best area to stay in Koh Samui?

It depends on the trip. Chaweng and Lamai on the east coast are best for beaches, restaurants and nightlife; the north around Choeng Mon and Bophut is quieter and handy for the airport; and the south is the most private, the place for a villa on its own bay. Our guide above matches each area to the villas and resorts in it.

Is Koh Samui good for families?

Very. Many of the island's villas and resorts are built for families, with multiple bedrooms, private pools, staff and kids' facilities, and the calmer beaches, short airport transfers and easy infrastructure make it low-stress with children. Staffed villas in particular, with a private chef and space to spread out, work especially well for a multi-generational trip.

How many days do you need in Koh Samui?

Five to seven nights is the sweet spot for a beach-focused stay, enough to settle into a villa, explore two or three beaches, and fit in the Big Buddha, a marine-park trip and a night at the Fisherman's Village. Add days if you are combining it with Bangkok or crossing to Koh Phangan for its quieter northern beaches.

Samui is smaller, greener and generally calmer, with a strong villa scene and Gulf weather that peaks mid-year; Phuket is larger and busier, with more to do, a wider hotel range and Andaman weather that peaks in winter. Choose by season as much as by preference, the two islands are at their best at opposite times of year.

Boutique Hotels in Koh Samui, Thailand

Where to stay in Koh Samui

Samui divides into its busy east coast, its quieter north, and the quiet south, and our collection is spread deliberately across all three. Villas dominate, but the settings vary widely.

Chaweng and the east coast

Chaweng is Samui's main event: the longest, best beach on the island, a couple of miles of white sand, backed by the busiest concentration of restaurants, bars and shops. Its quieter southern curve, Chaweng Noi, is separated by a headland and calmer for it. This is where you stay to be in the thick of things, and where two of our villas make the most of the address. Villa Mia is a staffed beachfront estate of three villas at the quiet northern end of Chaweng, bookable singly or together, with the beach on one side and the restaurants a short ride away. Up in the hills above Chaweng Noi, Villa Moonshadow takes the opposite tack: an architect-designed four-bedroom villa with an infinity pool and a 180-degree sweep of sea, private, elevated and completely calm.

Lamai and the quieter east

South of Chaweng, over the headland, Lamai is the island's second beach and a gentler proposition, a little cheaper, a little more local, with the famous Hin Ta and Hin Yai rock formations at its southern end.Ammatara Pura sits on a quiet stretch of Lamai sand, an intimate resort of eighteen private-pool villas built in an ornate, palace-style Thai design, with the warm, family-run service that is its real signature and the town a couple of minutes' walk away.

The north and Thongson Bay

The north coast is quieter than the east and handy for the airport and the Big Buddha. Around Choeng Mon and Thongson Bay, the beaches shrink to intimate coves and the mood softens. Melati Beach Resort & Spa occupies its own bay here, a beachfront resort of seventy-seven rooms and pool villas built around a waterfall lobby, with a spa and a broad stretch of private sand, an easy, full-service base a short hop from the airport.

The quiet south

The south and south-west of the island are the least developed parts, a landscape of coconut groves, fishing villages and small private bays that the resort strip never reached. Villa Kalyana has one of these to itself: an exclusive-use, twenty-six-bedroom beachfront estate on its own bay, fully staffed and privately chefed, built for a big group or an extended family that wants the run of a private beach. It is the island at its most private, and its most all-in.

What to do

Beyond the beach, Samui repays a day or two of exploring. See the Big Buddha and the Wat Plai Laem temple in the north-east; take a longtail out to the Ang Thong Marine Park, the archipelago of limestone islands that inspired The Beach; and drive the ring road inland to the Na Muang waterfalls and the coconut country of the interior. The Fisherman's Village at Bophut, an old Chinese-Thai trading street of wooden shophouses now full of restaurants, is the best place on the island for dinner and a wander, especially on Friday market night.

When to go

Samui keeps a different calendar from Thailand's Andaman coast. The best, driest weather runs from around December to August, with the peak of the dry season in the middle of the year, exactly when Phuket is wet. The wettest, roughest stretch is October to December, when the north-east monsoon can bring heavy rain and choppy seas. For the finest weather, and the trade-off of higher prices, aim for the January-to-April window, or the middle of the year for value and reliable sun.
