Mafia Island, Tanzania

A Hidden Gem of the Indian Ocean

Far from the crowds of Zanzibar and off the beaten tourist track lies Mafia Island — an unspoiled paradise where pristine coral reefs, abundant marine life, and authentic Swahili culture await those seeking a quieter, more nature-focused escape. Located off the southern coast of Tanzania, Mafia is part of the Mafia Archipelago, a cluster of islands that remain one of the best-kept secrets in East Africa.

Whether you're diving with whale sharks, exploring mangrove forests, or relaxing under the shade of a palm tree, Mafia offers a rare chance to connect with nature and tradition in a setting untouched by mass tourism.

Where Is Mafia Island?

Mafia Island is located about 30 minutes by plane from Dar es Salaam, Tanzania’s largest city. It lies within the Mafia Archipelago, which includes smaller islands like Juani, Chole, Jibondo, and Bwejuu, scattered across the warm waters of the Indian Ocean.

Despite its name, Mafia has nothing to do with crime syndicates — the name likely comes from the Arabic "Morfiyeh", meaning "group" or “archipelago,” or the Swahili "Mahali pa Afya", meaning "a healthy dwelling place."

Why Visit Mafia Island?

1. Incredible Marine Life & Protected Reefs

Mafia is home to the Mafia Island Marine Park, the oldest marine protected area in Tanzania, covering over 820 km² of coral reefs, lagoons, seagrass beds, and mangrove forests. It’s a diver and snorkeler’s paradise, teeming with marine biodiversity.

2. Whale Shark Encounters

From October to March, Mafia is one of the best places in the world to swim with gentle whale sharks, the largest fish in the sea. These plankton-eating giants are often spotted close to shore in calm, clear waters.

3. Authentic Island Culture

Mafia has preserved much of its traditional Swahili heritage. With small fishing villages, local markets, and no commercial development, it offers a cultural experience that feels genuine and immersive.

4. Peaceful, Off-the-Grid Travel

With no large resorts, shopping malls, or party scenes, Mafia is perfect for nature lovers, honeymooners, families, and anyone seeking peace and simplicity in a stunning setting.
