    Nyumba Ya Casa, ‘House of Turtles’ in Swahili, pretty much delivers on its name. We’ve seen more green turtles here than almost anywhere else in Zanzibar, often just hanging out on the coral, seemingly unbothered by divers. This site is a pinnacle rising from the seabed, and it’s absolutely smothered in soft sponges. The colours really pop against the blue, especially when the light hits them just right. We love Nyumba Ya Casa for its chill vibe and the reliable turtle encounters. The max depth of 17m makes it a relaxed dive, perfect for photographers or anyone who just wants to take their time. Look closely among the sponges for moray eels peering out, and we’ve spotted stonefish here too, so keep an eye on your buoyancy. Visibility generally hovers around 12-15m, which is good enough to appreciate the scale of the pinnacle and the sponges. It’s a great spot for a morning dive, before any potential afternoon chop picks up.

    Safety Notes

    Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
