Koh Samui
Twenty of the island's finest five-star properties — private pools, sea views, world-class spas and the kind of service that makes a holiday unforgettable.
Why Koh Samui is
Asia's Finest Luxury Destination
Koh Samui is home to some of Asia's most extraordinary five-star resorts — properties that define what luxury travel should be. From the Four Seasons perched above Maenam Bay to the Conrad's legendary infinity pools on the west coast, the island offers a level of intimacy and natural beauty that larger destinations like Phuket or Bali simply cannot match. This is our definitive guide to the island's finest.
Resort Koh Samui
Perched on a dramatic hillside above Laem Yai Bay, the Four Seasons Koh Samui is widely considered the finest resort in Thailand. Sixty detached pool villas — each with their own infinity edge pool overlooking the Gulf — are attended by dedicated Guest Experience Makers. The sense of absolute privacy combined with world-class service and cuisine makes this resort genuinely exceptional.
Koh Samui
Built on a former coconut plantation spanning 58 acres, the Ritz-Carlton sits directly on Choeng Mon Beach with stunning ocean views from every villa. The resort's cliff-top pool villas feature perhaps the most spectacular private infinity pools on the island. With a Spa Village featuring eight treatment suites and a dedicated Ritz Kids programme, it excels for both couples and families seeking true indulgence.
Koh Samui
Named the Number One Luxury Honeymoon Hotel in South-East Asia, Conrad Koh Samui occupies 25 acres of tropical hillside on the island's secluded west coast. Each of the 81 private pool villas features a 10-metre infinity pool seemingly suspended above the ocean — quite simply some of the most breathtaking views in all of Thailand. The hilltop fine dining restaurant and sunset vantage point are worth the stay alone.
Samui
Perched on the rugged northeastern headland of Koh Samui, Six Senses Samui delivers the brand's signature blend of wellness, sustainability and understated luxury. Pool villas are built into the rocky hillside with stunning unobstructed views of the Gulf. The spa is among the finest in Asia, and the resort's commitment to local sourcing and environmental responsibility adds a layer of purpose to the indulgence.
