The Big Wall
Why dive here
With 312+ marine species recorded in the area - including barracuda, blue-spotted stingrays, dolphins, eagle rays and hammerhead sharks - The Big Wall offers some of Zanzibar & Pemba's richest drift diving. Water ranges 26-30°C, warmest February, March, April.
The Big Wall delivers exactly what the name promises: a serious vertical drop. We love the sheer scale of it, plunging from a comfortable 24 metres down to a hazy 60 metres or more. It’s less about a frantic search for tiny critters and more about soaking in the grandeur of the ocean. We always make a point of checking out the small caves and overhangs carved into the wall. That’s where you’ll often find lobsters tucked away and sometimes a stingray resting on the sandy ledges. Keep an eye out for Titan triggerfish; they’re often patrolling the wall, looking for an easy meal. If you hit it between June and September, there's a real chance of spotting hammerhead sharks cruising out in the blue. We'd suggest this site for confident divers who appreciate dramatic topography and don’t mind a bit of current, as it can get lively here.
