Snorkelling Chumbe Island Coral Park

Tanzania's first marine park: rangers, 500 reef fish and no fishing since 1992. Chumbe's fringing reef has been closed to fishing since 1992 and became Tanzania's first marine park in 1994, run by a non-profit. More than 500 reef fish species and almost 60 kinds of hard coral have been recorded. Rangers lead about an hour of snorkelling, with all the gear and floats provided, then a forest walk, an intertidal walk and the old lighthouse. Scuba diving is banned, numbers are capped, and day visits are taken only when the eco-lodge has space. How to book: Book direct (chumbeisland.com) — bookings open just four days ahead and are capped at about 14 visitors. Check in at 09:30 at Jungle Paradise Resort, about 10 minutes south of Stone Town, for the 10:00 boat. Staying overnight gets better reviews than the day trip.
