Mafia Island is a paradise for divers, fishermen and water sport lovers. The variety of coral permits an unimaginable quantity of fish: marlin, sailfish, shark, kingfish, barracuda, flying-fish, red mullet, tuna, wahoo and many more.
The fishing season is from September to March although fishing is possible all year round within the reef and channel. Scuba diving the pristine coral reefs is about as good as it gets. You might also enjoy an excursion to Jibondo Island to watch the hand-made fabrication of the dhows.
There are some sights to see too. A 13th century mosque has been excavated and fragments of Chinese pottery were found among the foundations.
