The Ritz-Carlton, Koh Samui

The Ritz-Carlton sprawls across 23 hectares of a former coconut plantation on the northeastern tip of Koh Samui, encompassing a private bay with two secluded beaches. Its 175 rooms, suites, and pool villas cascade up the hillside from the sandy beach. Suites start at 93 square meters. The bay boasts a swimming reef and a seasonal seawater pool—the resort claims is the only one in Thailand. The dining options are more diverse than at any other resort on this list, ranging from Pak Tai's southern Thai cuisine and beachfront barbecue to the Mediterranean menu at The View restaurant on the hill. However, some restaurants are closed at certain times, so be sure to check opening hours for your travel dates. The Spa Village offers eight treatment rooms and a private pool, and the Ritz Kids Club keeps children entertained. The only drawback is the resort's size. As it's a sprawling hillside resort, inquire about the location of your villa if you plan to walk to the beach. The airport is about 6 km away. Ideal for families and couples looking for a luxurious resort with a wide range of leisure activities.
