Tanzania’s islands has a combination of white-sand beaches, turquoise waters, coral reefs, marine life, Swahili culture and peaceful tropical landscapes. Zanzibar, Pemba and Mafia are among the country’s leading beach and island destinations.
If you are planning a Tanzania holiday, adding an island escape to your itinerary can turn a safari trip into a much more complete experience.
1. Zanzibar Island
Zanzibar is Tanzania’s best-known island destination and one of the most popular tropical getaways in East Africa.
The island combines beautiful beaches with a fascinating history and Swahili culture. Visitors can spend their mornings relaxing beside the Indian Ocean, explore the historic streets of Stone Town, take a spice tour or discover the coral reefs surrounding the island.
Zanzibar is also well suited to different types of travellers. Couples can enjoy romantic beach resorts, families can explore cultural and marine attractions, while adventure seekers can go snorkelling, diving, sailing or fishing.
2. Pemba Island
Pemba Island is a quieter and less developed alternative for travellers looking for a more peaceful island experience.
Often associated with lush vegetation and spice production, Pemba combines tropical forests, traditional communities, historic sites and beautiful coastal scenery. Its surrounding waters are particularly attractive to snorkellers and divers because of the coral reefs and marine life.
Travellers can also explore Pemba’s cultural heritage, including historic settlements and ruins, while experiencing a slower pace of island life. The Zanzibar tourism authorities highlight activities such as diving, snorkelling, fishing, forest exploration, spice tours and cultural experiences.
3. Mafia Island
Mafia is known for its marine environment, relaxed atmosphere and connection with the Mafia Island Marine Park. The island is particularly attractive to travellers interested in diving, snorkelling, marine life and quieter beach holidays.
The official Tanzania Tourism Board lists Mafia alongside Zanzibar and Pemba as one of Tanzania’s key beach destinations, while Tanzania’s Marine Parks authorities oversee the Mafia Island marine protected area.
Mafia is a good option if your idea of a holiday involves fewer crowds, nature and time in the ocean.
4. Mnemba Island
For travellers looking for exclusivity, Mnemba Island is one of Tanzania’s most famous private island retreats.
Located off the northeast coast of Zanzibar, Mnemba is surrounded by clear Indian Ocean waters and a coral reef that supports a variety of marine life. Snorkelling and scuba diving are among the major attractions.
The island is associated with luxury accommodation and a highly private beach experience, making it particularly popular with honeymooners and travellers seeking an upscale tropical escape. The Zanzibar Commission for Tourism also highlights snorkelling, scuba diving and other water activities around Mnemba.
Mnemba is not the destination to choose if you are looking for a cheap beach holiday. Its appeal is privacy, exclusivity and a high-end island experience.
5. Chumbe Island
Chumbe Island is particularly interesting for travellers who want to combine a beach holiday with conservation and environmental education.
It is known for its protected coral reef and forest environment. Activities can include guided forest walks, snorkelling and learning about marine conservation.
The island operates as an important conservation and eco-tourism destination, with visitor numbers and activities managed to protect its fragile environment.
This makes Chumbe different from a conventional resort island. The attraction is not simply the beach but the opportunity to experience a protected natural ecosystem responsibly.
6. Fanjove Private Island
Fanjove is another option for travellers searching for a secluded island experience.
It forms part of the Songo Songo Archipelago, south of Mafia Island. Its tropical environment includes beaches, coral reefs and warm Indian Ocean waters.
According to Tanzania Specialist, the surrounding marine environment attracts turtles and supports diverse wildlife both in the water and on land.
7. Other Islands Around Zanzibar
Zanzibar’s island experience is not limited to the main island. The wider archipelago includes numerous smaller islands and marine destinations.
Changuu Island, for example, is known for its history and marine attractions, while Bawe Island offers a quieter setting close to Stone Town. The Zanzibar Commission for Tourism also promotes destinations such as Chumbe, Mnemba, Pemba and other smaller islands as part of the region’s tourism offering.
These smaller islands can be ideal for day trips, snorkelling, boat excursions or simply enjoying the Indian Ocean away from busy urban areas.

The Zanzibar Commission for Tourism identifies June to October as a particularly favourable period for visiting Zanzibar, with pleasant weather and conditions suitable for outdoor experiences.
