Shetani is a shallow coral-wall dive off Tumbatu Island in Zanzibar, where the reef starts very shallow and steps down through colorful coral ledges and bommies. It is one of the island's easiest reef sites, with mild water movement, clear entry planning, and plenty of time to work the top of the reef. Turtles, moray eels, octopus, scorpionfish, and schools of juvenile fish are the usual draw, and the site also works well for snorkelers in calm weather.
