4 / WA ALE Mergui Archipelago, Myanmar

More than 90 minutes by speedboat from Myanmar’s southernmost port town, Wa Ale is the sole occupant of a wild, 1,600-hectare island in the Mergui Archipelago. Built using reclaimed materials, the resort, which reopens in November, is as intimate as it is sustainable, with just 11 tented suites and a trio of treetop villas. Languid days can be spent trekking in the jungle, kayaking through mangrove forests, and exploring the waters of Lampi Marine National Park, whose conservation the resort supports through its own foundation. waaleresort.com; from US$425 per person
