Zanzibar, an island paradise off the coast of Tanzania, is one of the most extraordinary destinations on Earth for swimming with sea turtles. Known for its turquoise lagoons, vibrant coral reefs, and warm Indian Ocean waters, Zanzibar offers visitors a rare chance to snorkel alongside green and hawksbill turtles in both protected sanctuaries and wild marine reserves.
Zanzibar’s turtle encounters are among the most reliable, sustainable, and accessible in East Africa. The island’s focus on conservation, combined with its idyllic tropical setting, makes it a world-class destination for eco-minded travelers.
Why Zanzibar Is a World-Class Destination for Turtle Snorkeling
Zanzibar’s geography and marine environment create the perfect conditions for sea turtles. The coral reefs around the island serve as both feeding and nesting grounds for green and hawksbill turtles, which are regularly seen by snorkelers. Unlike destinations where sightings are seasonal or unpredictable, Zanzibar’s turtles are present all year due to the consistent warmth of the Indian Ocean and abundant seagrass beds.
Another advantage is accessibility. Turtle snorkeling in Zanzibar doesn’t require long boat rides or expensive private excursions. Many reefs are close to shore, and even first-time snorkelers can enjoy encounters in calm, shallow water. The combination of rich biodiversity and community-led marine protection projects makes it one of the most authentic places to observe marine life responsibly.
Zanzibar’s northern and northeastern coasts, especially Nungwi and Mnemba Atoll, are the island’s primary turtle hubs. Local conservation centers rehabilitate injured turtles, while offshore reefs offer a more natural, open-sea experience. Visitors can choose between educational sanctuary visits or wild snorkeling tours depending on their comfort level.
Top Turtle Snorkeling Spots in Zanzibar
Nungwi Natural Aquarium (Baraka Aquarium)
Located at the northern tip of the island, the Nungwi Natural Aquarium, often called Baraka Aquarium, is a tidal lagoon filled with seawater from the Indian Ocean. It serves as a sanctuary for rescued sea turtles that are rehabilitated and released once healthy.
For travelers who want guaranteed encounters, Nungwi is an excellent starting point. The lagoon’s calm, shallow waters allow safe snorkeling even for beginners, and the guides provide educational insights into turtle biology and local conservation efforts. The entry fee of about $10–15 per person directly supports these programs.
Why it’s special: The Baraka Aquarium allows you to see turtles up close while supporting a community-run conservation initiative.
Pros:
- Reliable encounters in calm water
- Family-friendly and educational
- Easy access from most northern hotels
Cons:
- Not a fully wild environment
- Crowded during peak tourist hours
Insider tip: Visit early in the morning, ideally between 8:00–10:00 a.m., when the water is clearest and the lagoon is less busy.
Mnemba Atoll Marine Reserve
Mnemba Atoll, located off the northeast coast near Matemwe, is one of Zanzibar’s crown jewels. This private marine reserve, encircled by coral reefs, is home to abundant sea life – including large numbers of turtles, dolphins, and tropical fish.
Turtles can often be seen grazing among the seagrass meadows or gliding gracefully over coral outcrops. The visibility here often exceeds 25 meters, making it a favorite spot for underwater photography.
Tours to Mnemba typically depart from Matemwe or Kiwengwa Beach, lasting about half a day and costing between $35 and $60 per person, depending on inclusions such as equipment, transfers, and marine park fees (usually around $3–5).
Why it’s special: Mnemba offers a natural, wild snorkeling experience where turtles are seen in their true habitat.
Pros:
- Pristine coral reefs and clear water
- Consistent turtle sightings
- Excellent biodiversity and scenic backdrop
Cons:
- Occasionally choppy seas in the afternoon
- Requires boat access
Insider tip: The best snorkeling area is the western side of the atoll, where currents attract turtles and reef fish. Go in the morning to avoid wind and waves.
Tumbatu Island
Tumbatu Island lies northwest of Zanzibar and remains one of the island’s best-kept secrets. It is home to unspoiled coral gardens, shallow reef flats, and a large number of turtles that feed on seagrass close to the island.
Because Tumbatu is inhabited by a small, traditional community, access is controlled. Only licensed operators who respect local customs can organize visits. This makes Tumbatu ideal for travelers seeking a quieter and more authentic experience.
Tours usually cost between $70 and $100 per person and last half a day, including boat transfers and guide services.
Why it’s special: A truly off-the-beaten-path destination with incredible coral formations and minimal tourist traffic.
Pros:
- Remote and peaceful snorkeling site
- High likelihood of turtle sightings
- Excellent visibility and coral density
Cons:
- Limited access without local guides
- No amenities (bring everything you need)
Insider tip: Pack your own snorkeling mask and fins, as equipment rental is often not available on the island. Bring snacks and water, as there are no facilities.
Kendwa Reef
Just south of Nungwi, Kendwa offers easy-access snorkeling along its shallow reefs. Turtles are not as numerous here as at Mnemba, but the relaxed atmosphere and beautiful beaches make it ideal for casual snorkelers or families staying in nearby resorts.
Tours typically last 2–3 hours and cost $25–45 per person. Many operators combine turtle snorkeling with sunset cruises or dolphin-watching experiences.
Why it’s special: Convenient and beginner-friendly, with options for short, scenic excursions.
Pros:
- Easy to reach from most beach hotels
- Calm waters suitable for beginners
- Opportunity to combine snorkeling with other activities
Cons:
- Coral is less colorful in some areas
- Lower turtle density
Insider tip: Go at high tide for better visibility and access to deeper sections of the reef.
When to Go Turtle Snorkeling in Zanzibar
Zanzibar’s climate is warm year-round, but snorkeling conditions vary slightly with the seasons. The best time to snorkel is during the dry periods, when the ocean is calm and visibility is high:
- June to October (cool dry season): Comfortable temperatures, calm waters, and great visibility.
- December to February (hot dry season): Warm waters ideal for long snorkeling sessions.
Avoid the long rainy season (March to May) when heavy showers can stir up sediment and reduce visibility.
Turtle nesting season occurs between February and July, and if you visit during May to August, you might even see hatchlings heading to sea at protected beaches.
What to Bring for Turtle Snorkeling
- Snorkel gear: Personal masks and fins ensure comfort and hygiene.
- Rash guard and reef-safe sunscreen: Protects your skin and minimizes coral damage.
- Waterproof camera or GoPro: Capture your turtle encounters while maintaining a respectful distance (at least 3 meters).
- Dry bag: Keep valuables safe from splashes.
- Reusable water bottle: Stay hydrated without contributing to plastic waste.
- Towel and change of clothes: Especially useful after long boat rides.
Responsible Snorkeling and Turtle Conservation
Sea turtles in Zanzibar are protected under Tanzanian law, and several local NGOs and community groups are deeply involved in their protection. Always choose tour operators who follow responsible practices, including:
- Respecting marine park regulations
- Avoiding feeding or touching turtles
- Anchoring boats in designated zones
- Limiting the number of snorkelers in the water
Organizations such as the Mnarani Marine Turtles Conservation Pond in Nungwi and Sea Sense on the mainland have been instrumental in rehabilitating injured turtles and educating local communities. Supporting tours affiliated with these programs ensures that your visit has a positive impact.
Important: Never chase, grab, or block a turtle’s path. Even a gentle touch can stress these creatures and damage their protective mucus layer.
How to Reach Zanzibar’s Turtle Snorkeling Sites
If you’re staying in Stone Town, the main access routes to snorkeling locations are:
- To Nungwi: About 1.5–2 hours by car or taxi.
- To Matemwe (Mnemba departures): Around 1 hour by car, then a 20-minute boat ride.
- To Kendwa: Approximately 1.5 hours by car.
Private transfers cost around $40–60 one-way, but many snorkeling tours include round-trip hotel pickup. For budget travelers, shared shuttles or dala-dala minibuses are available, though they are slower and less comfortable.
