Explore the reefs off Zanzibar’s coast while snorkelling among clownfish and parrotfish. Around 600 species of fish live there as well as dolphins and turtles. Colourful corals and seagrass meadows stretch across the seabed. Zanzibar offers ideal conditions for snorkelling: pleasant water temperatures all year round and visibility of up to 30 metres, perfect for beginners and experienced snorkellers alike.

Snorkelling in Zanzibar’s famous Blue Lagoon

In the east of Zanzibar, the water of the Blue Lagoon glows a bright turquoise. A few metres below the surface, a colourful coral reef is home to pufferfish and angelfish. But above all, the Blue Lagoon is famous for its starfish. Our tip: combine your snorkelling dive off Zanzibar’s coast with a visit to The Rock restaurant, perched on a rock in the middle of the sea.
