Thanda Island Beach
The private-island beach is a category of its own — Thanda, 22 km off the Tanzanian coast, is rented whole for $12,000/night with chef, dive instructor, and 12 staff. Four beaches, no other guests, reef on three sides. The water is clearer than the Maldives and the access is harder, which is the point. For travellers who have done overwater villas and want the next thing.
