Ras Mbisi is a sustainably-built lodge on Tanzania's beautiful Mafia Island, set in tropical gardens next to eight kilometres of deserted beach. With its reputation for exceptional service and hospitality, the lodge focuses on relaxation but there's plenty to do when you are feeling active: explore powdery white beaches; marvel at the island's world-famous marine life; and wind things down with a sunset cruise. There are also coastal forests and mangrove creeks to explore.
Go fishing, snorkelling or even sea-kayaking where you may even be lucky enough to see whale sharks between November and February, and humpback whales between July and August. Children will be thrilled to witness turtle-hatching on the beaches between June and August. You can also just spend an afternoon lazing beside the swimming pool, just metres away from the beach, with a book from the library and a cocktail from one of the lodge bars.
