Mafia Island and Pemba: Choosing Tanzania's Quiet Beaches

While Zanzibar grabs the headlines and the lion's share of tourists, Tanzania’s coastline hides two secret gems that offer a glimpse of the East African coast as it was decades ago. To the south of Zanzibar lies Mafia Island, a rustic paradise renowned for its marine park and seasonal whale shark encounters. To the north lies Pemba Island, a hilly, fertile island famous for its clove plantations, deep-sea drop-offs, and dense indigenous forests.

If you are looking to escape the crowds, enjoy world-class diving, and experience authentic Swahili culture without the mass tourism, these islands are your answer. But how do you choose between them? In this guide, we break down the geography, wildlife, activities, and lodging options of both Mafia Island and Pemba to help you select the perfect sanctuary.

Quick Summary Table

Mafia Island: The Marine Sanctuary

Mafia Island is the largest island in a small archipelago that lies about 130 kilometers south of Dar es Salaam. It remains remarkably untouched by major commercial developments. The island is flat, sandy, and surrounded by a complex system of barrier reefs, channels, and mangrove forests.

The Highlight: Swimming with Whale Sharks

One of the most extraordinary wildlife encounters in Africa occurs in the shallow waters off the west coast of Mafia Island. From October to February, nutrient-rich waters attract large congregations of whale sharks (Rhincodon typus). These gentle giants, often measuring up to 10 meters in length, feed calmly near the surface, allowing snorkelers to swim alongside them. Unlike other global destinations, the whale shark encounters in Mafia are managed ethically, with strict guidelines to ensure the animals are not stressed or crowded.

Chole Bay & the Marine Park

Over half of the waters surrounding Mafia are protected under the Mafia Island Marine Park (Tanzania's first marine park). The epicenter of this park is Chole Bay, a deeply indented, sheltered bay that acts as a natural nursery for marine life. Inside the bay, you’ll find shallow coral gardens, seagrass beds, and mangrove forests. Outside the bay, dramatic walls drop down into the deep blue channel, attracting reef sharks, barracudas, and massive groupers.

Historical Ruins of Chole Island

Just off the shore of Mafia lies Chole Island, a tiny islet where time seems to have stood still. Walking through the island reveals ancient ruins of 19th-century Arab and German settlements, overgrown by giant wild fig trees. It is also home to a sanctuary for the rare Comoro flying fox (a giant fruit bat).

Pemba Island: The Green Island

Known historically as Al-Jazeera Al-Khadra (The Green Island), Pemba is located north of Zanzibar. Unlike Zanzibar and Mafia, which are flat, coral islands, Pemba is hilly, fertile, and dissected by deep valleys. It produces around 70% of Tanzania’s clove exports, and the scent of drying cloves often fills the warm tropical air.

The Highlight: Deep Wall Diving & Pristine Reefs

Pemba is separated from the African mainland by the deep Pemba Channel, which plunges to depths of over 1,000 meters. This deep water brings nutrient-rich currents that feed some of the healthiest coral reefs in East Africa.
* The Diving: Pemba is famous for its vertical wall dives. The reef drops straight down into the abyss, covered in giant sea fans, colorful soft corals, and sponges. You stand a high chance of seeing pelagic species such as hammerhead sharks, sailfish, and manta rays.
* Misali Island: Located off the west coast of Pemba, Misali Island is an uninhabited marine sanctuary featuring crystal-clear waters, nesting green turtles, and coral reefs that start right at the shoreline.

Ngezi Forest Reserve

In the north of Pemba lies the Ngezi Forest, a rare remnant of the original primary rainforest that once covered the island. Walking along the wooden boardwalks, visitors can spot endemic wildlife like the Pemba flying fox, the Pemba vervet monkey, and the rare Pemba scops owl.

Comparison: Mafia Island vs. Pemba Island

To help you decide which island suits your travel style, consider the following key differences:

Luxury and Eco-Lodges

Because these islands host fewer tourists, their accommodation options tend to be boutique, eco-conscious, and deeply integrated into the local communities.

Top Lodges in Mafia Island

• Pole Pole Bungalows: Meaning "slowly slowly" in Swahili, Pole Pole is an award-winning eco-lodge situated on the shores of Chole Bay. It features just seven luxury bungalows constructed from local timber and thatch, blending seamlessly into the coconut palms. The lodge is famous for its gourmet Italian-Swahili fusion cuisine and low environmental footprint.
• Chole Mjini: Located on Chole Island, this unique lodge consists of luxury treehouses built around ancient baobab trees. It offers a rustic-chic castaway experience with open-air bathrooms and gorgeous views of the bay.

Top Lodges in Pemba Island

• Fundu Lagoon: Accessible only by boat, Fundu Lagoon is located on a remote beach in the southwest of Pemba. It features luxury safari-style tents set on wooden decks, some nestled on the hillside and others directly on the beach. It offers a sophisticated, barefoot-luxury atmosphere with an exceptional PADI dive center.
• The Manta Resort: Situated on the northern tip of Pemba, this resort is famous for its Underwater Room—a private, three-story floating suite anchored in a blue hole. The bedroom is submerged four meters below the surface, offering 360-degree views of reef fish swimming past your windows at night.

What to Pack for Remote Tanzanian Islands

Traveling to remote islands like Mafia and Pemba requires careful packing, as there are no convenience stores or pharmacies outside the small local villages.

Remote Island Packing Checklist

• [ ] Reef Shoes / Booties: Vital for wading through shallow lagoons and walking on coral flats.
• [ ] Biodegradable, Reef-Safe Sunscreen: Crucial to prevent chemical damage to the pristine corals.
• [ ] High-strength Insect Repellent: Both islands have malaria-carrying mosquitoes, so protection is vital.
• [ ] Modest Beachwear & Cover-ups: Necessary when walking through villages or visiting local spice farms.
• [ ] Personal First-Aid Kit: Include antihistamines, rehydration salts, sea-sickness medication, and basic antibiotics, as medical facilities are limited.
• [ ] Cash (Tanzanian Shillings or USD): Lodges accept cards, but local guides, dive tips, and village shops require cash. Ensure USD bills are crisp and printed after 2006.

Travel Logistics: How to Get There

Both islands require a domestic flight from the Tanzanian mainland or Zanzibar.

• To Mafia Island: Daily scheduled flights operate from Dar es Salaam (DAR) to Mafia’s airstrip (Kilindoni). The flight takes approximately 30 to 45 minutes on light aircraft (operated by Coastal Aviation or Auric Air).
• To Pemba Island: Scheduled flights run daily from both Zanzibar (ZNZ) and Dar es Salaam (DAR) to Pemba's airport (Chake Chake). The flight from Zanzibar takes about 30 minutes.
