Sea walking at Nungwi

Walk on the seabed in an air-fed helmet — no swimming needed. Zanzibar SeaWalk takes you out by boat to a platform off Nungwi, fits you with an air-fed helmet and lets you walk the sandy seabed for about twenty minutes among sergeant majors and reef fish. You don't need to swim or dive, and you can keep your glasses on. How to book: Book with Zanzibar SeaWalk (zanzibar-seawalk.com), based at Double A Beach Hotel in Nungwi. Some packages include photos and video.
