Leven Bank

This advanced site is a thrill-seeker’s dream. Located in deep water, it’s perfect for experienced divers. Expect strong currents, but also large pelagic fish and sometimes even hammerheads!

Tumbatu Island

A lesser-known gem with shallow reefs perfect for beginners. It’s also a great spot for night dives.

Stone Town Reefs

If you’re based in the historic Stone Town, the surrounding reefs offer great macro life and the occasional surprise—like a seahorse hiding in the coral.

Best Time to Go Scuba Diving in Zanzibar

Zanzibar enjoys two main diving seasons:

  • June to October: Cooler but clearer waters. Great visibility and lots of marine life.

  • December to March: Warmer waters and excellent diving conditions.
    Avoid the long rainy season in April and May, as dive visibility may decrease.
