Seven Seas Resort

Seclusion is one of the most attractive amenities at the resort, on a 237-acre island reserve 170 miles south of Phuket. This borders an isolated stretch of powdery white sand, and the 32 thatched-roof villas—outfitted with pine furniture—open onto spacious sundecks screened by giant coconut trees. Snorkelers can come face-to-face with the endangered sea cow, one of the Andaman’s gentle giants, as well as sea horses and ghost pipefish.
