Tumbatu Lagoon - Zanzibar & Pemba
Blue Pyjamas, a quick boat ride from Gizo, is one of those places we often head to when the southeast trades kick up. It’s a well-protected channel, meaning the surface is usually calm and the dive is tranquil, just as the name implies. The reef starts shallow, around 2 meters, perfect for a bit of sun-drenched snorkeling or freediving, then slopes down to about 19 meters for divers. We love poking around the swim-throughs and small caves – they’re not grand caverns, but good fun, and we often spot resting turtles or the occasional bumphead parrotfish cruising by. Visibility averages a comfortable 18 meters, making it a relaxed dive for anyone looking to just enjoy the reef without battling currents.
