"A calm, eco-conscious alternative to nearby Phuket on the hush-hush island of Koh Yao Noi, reached by a 30-minute speedboat. The resort channels a castaway vibe with driftwood-and-thatch villas, a secluded beach and a village-like spa focused on all-natural remedies, while social highlights include sunset cocktails at the Den, wine evenings at the glass-floored Nithan restaurant and spectacular sunrises over the karst-studded horizon." - Chris Schalkx
