The short answer: The Four Seasons Resort Koh Samui is the best hotel on the island. It has hillside private-pool villas, a jungle spa, and the cachet of hosting HBO's White Lotus season three. For eco-luxury and wellness, book Six Senses Samui. For an all-pool-villa resort on a private cove, book Banyan Tree Samui. For sunsets, book Conrad Koh Samui. Families will find the easiest fit at Kimpton Kitalay. Top villas typically run $500 to $1,500+ a night in peak season. No placement on this page is paid.
Koh Samui is Thailand's calmer, more romantic island. Phuket has more energy and variety, while Samui leans toward villa resorts and quiet bays. It's also the island that White Lotus made famous. Samui has a useful quirk. Its weather runs on a different pattern from Phuket, so it's often at its best in summer, when the Andaman coast is rainy.
Where to Stay in Koh Samui
The further you go from Chaweng, the quieter it gets. The northwest coast is home to the Four Seasons. The northern tip has Six Senses, with panoramic views over the Gulf. The northeast, around Choeng Mon, is stylish and calm, with the Kimpton Kitalay and the Ritz-Carlton.
Chaweng is the buzzy center, with nightlife and restaurants within walking distance. The southwest hillside, at Taling Ngam, is ultra-private, with dramatic sunsets and the Conrad. The southeast near Lamai is lush and peaceful, home to Banyan Tree and Kamalaya.
One note on pricing: full all-inclusive resorts are rare on Samui. Most luxury rates are room-only or include breakfast, with dining and spa extra.
Four Seasons Resort Koh Samui
The Four Seasons is the island's benchmark. It sits in a coconut grove that cascades down to the Gulf of Thailand, with private-pool villas spread across the hillside. It feels totally secluded without feeling remote.
It's also globally known as the filming location for White Lotus season three, which has made it one of the most searched hotels in Asia. Beyond the fame, the service and villa space are excellent, and there's a kids' program. The honest caveat: expect high demand and high rates, especially in December.
Best for couples, honeymooners, and families who want villa space.
Six Senses Samui
Six Senses is the eco-luxury pick. It sits on the island's northern tip with panoramic Gulf views and a strong wellness program. Many ingredients come from the resort's own garden and elsewhere in Thailand.
It's a favorite for honeymoons, and the service gets consistent praise. Best for wellness travelers and couples.
Banyan Tree Samui
Banyan Tree is the original Thai flagship of the brand, and every villa has a private pool. Jungle paths link the villas to a private beach cove on Lamai Bay, where you can snorkel and paddleboard in calm water. The Banyan Tree spa is one of the best on the island. It's a classic that still delivers two decades on.
Best for honeymooners and privacy seekers.
Conrad Koh Samui
The Conrad sits high on the southwest hillside with some of the best sunset views on the island. Every villa has an infinity pool, and it's been named one of the top honeymoon hotels in Southeast Asia.
The honest caveat: it's a hillside resort far from town, so you'll rely on shuttles and taxis. Best for couples and sunset chasers.
Kimpton Kitalay Samui
Kimpton Kitalay is the best family resort on Samui. It sits on the quiet shores of Choeng Mon Beach, with a palm-lined Olympic-size pool, five restaurants and bars, a beachfront, and the Pimãanda spa. There are 138 rooms, suites, and villas, including 21 with private pools. It's more casual than the Four Seasons, with free bikes and a village feel.
Best for families and travelers who want relaxed luxury.
The Ritz-Carlton, Koh Samui
The Ritz-Carlton is a large oceanfront resort with 175 suites and pool villas on 58 acres of a former coconut plantation. It overlooks two white-sand beaches, with a huge spa and six places to eat. It's a reliable choice for families and Marriott travelers. Best for families and points travelers.

Kamalaya
Kamalaya is Samui's world-class wellness retreat. It's built around a monk's cave in the southeast and focuses on detox, yoga, and holistic programs.
Best for travelers who want a dedicated wellness stay rather than a beach holiday.

Best Time to Visit and Book Koh Samui
Samui's best weather usually runs from January through August. The wettest months are typically October and November, when the east coast monsoon arrives. That's the opposite of Phuket, which makes Samui a strong choice for a summer trip to Thailand.
December through February is peak season, with the highest rates. Book those dates two to three months ahead, and even earlier for Christmas and New Year's. Villas at the Four Seasons and Banyan Tree book out first.
Getting there is easy. Bangkok Airways flies to Samui's small airport from Bangkok and other hubs.
