What You Need to Know About Swimming with Zanzibar Sea Turtles
Imagine gliding through the warm, crystal-clear waters of Tanzania’s Indian Ocean, side-by-side with one of the ocean’s oldest and most majestic aquatic species — the sea turtle. Zanzibar is home to both Green Sea Turtles (Chelonia mydas) and the endangered Hawksbill Turtles (Eretmochelys imbricata), two species that play a crucial role in maintaining the health of marine ecosystems.

Introduction to Swimming with Turtles
Swimming with turtles is an exhilarating experience that allows individuals to interact with these fascinating creatures in their natural habitat. Many visitors bring snorkeling masks to dive and experience the underwater world, offering a unique opportunity to swim and interact with these marine creatures. Turtle species such as leatherback sea turtle, green sea turtle, and others can be found in the oceans around the world, including the Indian Ocean near Zanzibar. Swimming with Zanzibar sea turtles provides a unique opportunity to observe their behavior, learn about their habitat, and appreciate their importance in the marine ecosystem. Many tour operators, such as Good Earth Tours, offer guided turtle swimming experiences that ensure a safe and enjoyable encounter for both humans and turtles.
Best Places to Swim with Sea Turtles in Zanzibar
If you’re dreaming of swimming alongside sea turtles in Zanzibar, you’re in luck! Here are the best spots to make it happen: Stone Town, the cultural and historical heart of Zanzibar, offers unique architecture and rich history. Additionally, the south east region of Zanzibar, including Kuza Cave, provides unique experiences such as swimming, cooking lessons, and cultural activities.
1. Nungwi Natural Aquarium (Mnarani Aquarium)
Located in the northern village of Nungwi, the Nungwi Natural Aquarium is a sanctuary for injured and rescued sea turtles. Here, you can swim with many turtles in a large natural lagoon filled with seawater.
Visitors can feed the turtles sea weed and even join in conservation talks to learn more about protecting marine life.
2. Baraka Natural Aquarium
Just a short distance from the Nungwi Aquarium, Baraka Natural Aquarium offers a similar experience. You can swim and interact with sea turtles in a more informal setting, making it ideal for families and casual visitors. Turtle eggs play a crucial role in conservation efforts, as local communities contribute by bringing in found eggs for hatching, helping to protect turtle populations. The turtles here are friendly and accustomed to human interaction, offering an unforgettable close-up encounter.
3. Wild Snorkeling Adventures – Mnemba Atoll
While swimming with turtles at aquariums offers a guaranteed encounter, adventurous travelers might spot turtles in the wild while snorkeling at Mnemba Atoll, one of Zanzibar’s top marine reserves. While snorkeling, you can also encounter a variety of fish and other marine life, making it a vibrant underwater experience. Several snorkeling tours offer day trips to Mnemba, where you might see sea turtles gliding freely through coral reefs in deep water.
Turtle Reproduction and Life Cycle
Turtles reproduce by laying eggs, which are often vulnerable to predators and human activities. Female turtles, such as the green sea turtle, lay their eggs on beaches, where they incubate for several weeks before hatching. The hatchlings then make their way to the ocean, where they begin their journey as tiny turtles. As they grow, they face numerous challenges, including predators, fishing nets, and habitat destruction. Adult turtles, such as the leatherback sea turtle, can live for many decades, and some species, like the giant tortoises, can live for over a century. Understanding the life cycle of turtles is crucial for developing effective conservation strategies to protect these incredible animals.
Conservation Efforts
Turtles face numerous threats, from habitat destruction and pollution to overfishing and climate change. Many turtle species, including the leatherback sea turtle, are endangered, with some teetering on the brink of extinction due to human activities like fishing and coastal development. Conservation efforts are vital to protect these ancient mariners and their habitats. Initiatives include establishing protected areas, enforcing regulations to prevent overfishing, and promoting habitat restoration. Organizations such as the Sea Turtle Conservancy and the Turtle Conservation Society are at the forefront of these efforts, working tirelessly to safeguard turtle populations and educate the public on the importance of conservation. In Zanzibar, local initiatives like the Baraka Natural Aquarium and the Mnarani Marine Turtles Conservation Pond are making significant strides in protecting sea turtles and their habitats. These sanctuaries not only offer tourists the chance to swim with turtles but also provide valuable education on conservation efforts. By supporting these initiatives and making sustainable choices, we can help ensure that turtles continue to thrive for generations to come.

How to Swim with Turtles Responsibly
While swimming with Zanzibar sea turtles is magical, it’s crucial to do so responsibly:
- Keep a respectful distance: Let the turtles approach you if they wish — never chase or touch them.
- Avoid using sunscreen that harms coral reefs: Choose reef-safe products that are safe for both saltwater and fresh water environments.
- Support eco-friendly operators: Choose sanctuaries and tours that prioritize conservation.
- Never feed wild turtles: Only feed turtles under the guidance of trusted sanctuaries.
- Leave no trace: Take all litter with you to protect the marine environment.
By following these simple guidelines, you can enjoy your experience without harming the environment or its previous inhabitants.
Health and Safety Precautions
When swimming with Zanzibar sea turtles, it is essential to take health and safety precautions to avoid harming both humans and the turtles. Despite spending large amounts of time underwater, turtles need to surface regularly to breathe air. This includes avoiding touching or riding turtles, as this can cause them stress and injury. It is also important to avoid feeding turtles, as this can disrupt their natural diet and lead to dependence on humans. Additionally, swimmers should be aware of their surroundings and avoid swimming in areas with strong currents or other hazards. By taking these precautions, individuals can ensure a safe and enjoyable experience for both themselves and the turtles.
Best Time to Swim with Turtles
The best time to swim with turtles depends on the location and the species of turtle. In Zanzibar, the best time to swim with turtles is during the dry season, from December to March, when the waters are calm and clear. During this time, the sea turtles, including the leatherback sea turtle and the green sea turtle, can be found in the waters around the island, feeding on seaweed and other marine plants.
