Swim with whale sharks in Zanzibar
Mafia Island, Zanzibar, Tanzania
Last updated: 21 March, 2024
From October to March, the west coast of Mafia Island offers one of the best opportunities to snorkel with the magnificent whale shark.
The biggest fish in the sea, growing up to 12m long with giant gaping maws, these harmless, plankton-feeders are attracted here in numbers by (it is believed) the krill-rich discharge of a nearby shrimp hatchery.
The sharks are massive, but completely harmless, and wild – they’re not fed or enticed towards swimmers. Whale sharks are fast swimmers; watch them pass by, then hop back on the boat to get in front of them again. For the shark’s wellbeing, though, don’t try to touch them or get too close.
Close to shore, and requiring only basic swimming ability, this world-beating experience is also highly accessible.
