The Sarojin Thailand

An ancient ficus tree anchors the grounds of this adults-only beachfront boutique resort in Khao Lak, where a long white-sand beach meets a lagoon on the opposite side. The Michelin Guide awarded it two Keys. Rooms are built from local materials that settle into the landscape rather than compete with it, and the spa sits among mangroves in open-air pavilions facing the sea. Yacht trips, canoe safaris, and jungle treks fill out the days for those who'd rather not stay horizontal.
