Abbas reef - Zanzibar & Pemba

Abbas Reef, just a quick hop from Kizimkazi, is one of those places we always recommend for a relaxed afternoon. It’s got a gentle vibe, perfect if you’re still building confidence, but don’t let that fool you into thinking it’s boring. We found a surprising density of activity here, especially in the shallower sections. The reef itself is a pretty healthy patch of coral, not enormous, but what’s there is vibrant. We’ve drifted over sandy patches thick with seagrass, spotting green turtles grazing – always a treat. Keep an eye out for the smaller stuff too. We’ve seen blue-spotted stingrays half-buried in the sand, their electric blue spots popping against the beige, and a few times, we’ve been lucky enough to spot seahorses clinging to the weed. The nudibranchs here are surprisingly colourful, a real photographer’s delight if you’re patient. Visibility hovers around 15 metres, often better on a calm day, and with a maximum depth of 15 metres, you get plenty of bottom time to explore. It’s an easy, unhurried dive, great for focusing on macro life or just enjoying a peaceful drift.
