Zanzibar is where the ocean feels alive. Warm, clear waters hug the coastline, hiding some of the richest marine ecosystems in East Africa. If you’re looking for top-tier snorkeling or diving, this island delivers, whether you’re a first-timer or seasoned pro. From the coral-covered shallows of Mnemba Atoll to the dramatic walls near Pemba Island, Zanzibar’s underwater world is nothing short of spectacular.

Marine life here is incredibly diverse. You’ll find playful dolphins, turtles gliding past coral heads, shoals of reef fish, and if you’re lucky, even a whale shark cruising by. The diving conditions are friendly all year, with great visibility and plenty of dive shops offering PADI-certified courses and guided excursions.
