Anjajavy l’Hôtel, Madagascar

011/26/187/366/275-0676 or anjajavy.com

Arrive at this Indian Ocean retreat on the hotel’s private plane. Once settled into one of 25 rosewood villas, guests can take guided hikes through the tropical forest, snorkel, mountain bike, or even water-ski.

Eco cred: Anjajavy has brought economic development and health programs to a remote and poor corner of the island. The property is next to an 1,100-acre nature preserve.

Insider’s tip: Don’t miss afternoon tea in the Oasis garden, where birds and lemurs are as much an attraction as the cake.
