Tanzania's Zanzibar Archipelago offers some of the finest snorkelling in the Indian Ocean. Warm, clear turquoise water, vibrant coral reefs and abundant marine life — from colourful reef fish to turtles and dolphins — make it a highlight of any visit. Reached by boat from the island's beaches, the reefs and atolls are accessible to complete beginners and rewarding for experienced snorkellers alike.
Reefs and atolls
The coral reefs around Zanzibar and its outlying atolls and sandbanks are warm, clear and teeming with life. Boat trips reach the best reefs, often combining snorkelling with a dhow cruise, dolphin-watching or a sandbank stop. The water is warm year-round and the visibility excellent in the drier seasons.
Boat trips and guided sessions
Local operators provide equipment and guidance, choosing reefs to suit the conditions and the group. Sessions suit beginners, families and confident swimmers.
