The Ultimate Guide to Mafia Island: Tanzania’s Best-Kept Marine Secret
While the world flocks to Zanzibar, the savvy traveler looks further south to Mafia Island. Known as the “hidden gem” of the Indian Ocean, Mafia Island offers a serene, sound-mind experience where nature remains wild and the local culture remains untouched by mass tourism.
At Karibu Zanzibar Agency, based in the heart of Nungwi, we specialize in bridging the gap between the vibrant energy of Zanzibar and the tranquil wonders of Mafia. Whether you are a diver, a history buff, or a nature enthusiast, Mafia Island is a sanctuary waiting to be explored.
1. The Stars of the Sea: Whale Sharks & Marine Life
The crown jewel of Mafia Island is the Whale Shark (Rhincodon typus). Unlike other global destinations, Mafia’s whale sharks stay for long periods, feeding on the plankton-rich waters of the Mafia Channel.
Best Time to Visit
The season runs from October to February, with peak sightings in December and January.
The Experience
These gentle giants can grow up to 12 meters. Snorkeling with them is a regulated, eco-friendly activity that ensures their protection while giving you a life-altering encounter.
Humpback Whales
Visit between September and November to witness the majestic Humpback whale migration.
2. Marine Adventures & Water Sports
Mafia Island is home to the first Marine Park in Tanzania, covering over 800 square kilometers of protected coral reefs.
Scuba Diving & Snorkeling
Explore Chole Bay, a world-class diving site with over 400 species of fish and 50 types of coral.
Key Sites
Kinasi Pass, Milimani, and the Dindini Wall.
Deep-Sea Fishing
From August to March, the Mafia Channel becomes a playground for game fishing, targeting Tuna, Marlin, and Barracuda.
Kayaking & Canoeing
Navigate the lush mangrove forests of the Emerald Channel or the calm waters surrounding the islets.
3. Island Hopping: Chole, Juani, and Jibondo
Each island in the Mafia archipelago has its own soul.
Chole Island
A step back in time. Witness the ancient art of traditional dhow building and visit the famous Popo Park, home to giant Comoros Fruit Bats (flying foxes).
Juani Island & Kua Ruins
History comes alive at the Kua Ruins, the remains of a 12th-century Swahili settlement.
Jibondo Island
Famous for its skilled sailors and incredible shark-skin leather crafts, this island offers a deep dive into the authentic fishing lifestyle of the Swahili coast.
4. Nature and Wildlife Beyond the Water
The Hippo Pools
Believe it or not, Mafia has wild hippos! Found in the reed-lined freshwater pools on the interior of the island (Juani), these “sea-faring” hippos are a biological wonder.
Turtle Hatching
From June to September, visit the eastern beaches of Juani Island to watch tiny green turtles make their first dash to the ocean.
Bird Watching
With over 120 species, including Fish Eagles and Palm-Nut Vultures, the northern forests are a birder’s paradise.
5. Land & Air: Exploring the Island
Road Trips
Take a 4×4 or a bicycle to Ras Mkumbi in the north to see the 150-year-old lighthouse built by the Germans.
Cultural Visits
Explore Kilindoni Market, the island’s hub, where you can buy hand-woven mats and taste local street food.
