Swim With Turtles in Zanzibar Waters.
Where Can I Swim With Turtles in Zanzibar? Zanzibar is one of the few areas in East Africa where visitors can get close to the sea turtles in warm, shallow Indian Ocean waters, as well as enjoy a relaxed island holiday. Many people are searching, ‘Where can I swim with turtles in Zanzibar?’ ‘ are surprised to learn that this experience is not to be found at a single beach but rather at a handful of specific conservation sites and marine areas around Unguja Island, the main island of Zanzibar.
These places combine reef snorkelling, turtle rehabilitation, and ethical interaction, making Zanzibar one of the leading places for turtle interactions in Tanzania. From the northern fishing villages of Nungwi and Kendwa to the more sedate eastern coastline around Kizimkazi and Jambiani, escaping to swim with turtles in Zanzibar is easily accessible and rewarding for those who know where to go.
Why Zanzibar is one of the best places to swim with sea turtles in Tanzania
Zanzibar on a Tanzania safari is located just off the coast of mainland Tanzania (divided by the Zanzibar Channel), surrounded by coral reefs, seagrass beds and shallow lagoons that provide natural feeding grounds for green turtles and hawksbill turtles. These two species are the most common turtles to be seen around Zanzibar. Green turtles graze on seagrass in the sheltered bays of the east coast, while hawksbill turtles like to head to the coral reef areas of Mnemba Atoll and the northern end of the island.
Because Zanzibar has been a long-time hub of fishing and trade, turtles were once hunted here, but conservation efforts have changed this. Today, turtle sanctuaries and marine protected areas have enabled turtles to recover and thrive, so it is possible for visitors to see and swim with them in the clear tropical water. The island’s tourism infrastructure also means that access to the island is easy from Abeid Amani Karume International Airport or by ferry from Dar es Salaam to Stone Town, which is the main gateway to turtle swimming locations within the island.
Mnarani Marine Turtle Conservation Pond in Nungwi
When people ask, ‘Where can I swim with turtles in Zanzibar?’ the best-known answer to this question is Mnarani Marine Turtle Conservation Pond in Nungwi. This sanctuary is at the northern tip of Zanzibar, in the village of Nungwi, about one hour by road from Stone Town. The site is near Nungwi Beach and the old fishing harbour, where dhow boats are constructed and launched.
Mnarani was set up to protect and rehabilitate injured and accidentally caught turtles. Local fishermen bring the turtles, which are found tangled in nets or injured by boat strikes, to the natural tidal pool where they are treated and nursed back to health before being released back into the ocean. Some of the turtles remain longer due to permanent injuries, and these turtles can be viewed by visitors in the large seawater lagoon.
Swimming with turtles here is done inside the protected pool. The water comes in and out with the tides, and it is therefore clean and connected to the ocean. Visitors are able to enter the pool under snorkels and swim with the turtles as they glide slowly through the water. Due to the turtles being used to people, they swim close and can be seen and photographed underwater clearly. While this is not a wild reef experience, it is one of the most reliable and ethical ways to swim with turtles in Zanzibar.
Nungwi is also a popular beach town with hotels, restaurants and dive centres, which makes it easy to combine turtle swimming with other things like snorkelling, sunset cruises and other trips to nearby Kendwa Beach.
Kizimkazi Mkunguni Turtle Sanctuary on the Zanzibar south coast
Another key area to go swimming with turtles in Zanzibar is Kizimkazi Mkunguni Turtle Sanctuary, which is located on the south coast of the island, some 60 kilometres from Stone Town. Kizimkazi is better known for dolphin tours, but it is also home to a community-run turtle rehabilitation lagoon.
The Kizimkazi turtle project focuses on rescuing small turtles that are caught in fishing nets or are found stranded. The turtles are housed in a massive natural pool in which visitors can see them and swim in shallow water. Unlike Nungwi, this sanctuary is quieter and has fewer tourists, making it ideal for travellers wanting a calmer and more authentic experience.
Swimming here is more intimate because the environment is more rural; fishing boats, palm trees, and coral stone houses are lined up on the shore. The turtles here often are juveniles, making it easier to see the markings and movements up close. Kizimkazi can be reached by road from Stone Town, passing the villages of Jambiani and Makunduchi, and is often part of a southern Zanzibar day trip.
Encounters with wild turtles in Mnemba Atoll Marine Reserve
For travellers who wish to have the open-ocean experience of swimming with turtles, Mnemba Atoll Marine Reserve is number one. Mnemba is a small private island with a protected reef system off the northeast coast of Zanzibar, near Matemwe Beach. Boats depart from Matemwe, Nungwi and Kendwa to the atoll daily.
The reefs surrounding Mnemba are some of the best in Zanzibar, with coral gardens, reef fish and healthy populations of green turtles and hawksbill turtles. Turtles are commonly spotted by snorkelers feeding on seagrasses or resting near coral outcrops. Because this is a marine reserve, the fishing is restricted, and this allows marine life to flourish.
Swimming with turtles in Mnemba is entirely in the wild. There are no enclosures or feeding, which means that sightings are based on conditions and timing, but the odds are good, especially during the calmer months between October and March. The clear turquoise water and white sandy seabed make Mnemba one of the most photogenic places in Tanzania to go snorkelling for turtles.
Prison Island and Changuu Reef near Stone Town
Another place where people may see turtles is around Prison Island, also known as Changuu Island, which is about 5 kilometres off the coast of Stone Town. The island is known for the giant Aldabra tortoises on land, but the reefs around the island are known to attract sea turtles, too.
Boat trips from Stone Town combine a snorkelling visit at Changuu Reef with the island visit. While sightings of turtles can’t be guaranteed in this area, green turtles are occasionally observed in the seagrass areas and near coral patches. This is a good option for travellers who stay in Stone Town and do not have time to travel to the north or south of the island.
When is the best time to swim with turtles in Zanzibar
Turtles live year-round around Zanzibar, but sea conditions determine visibility and safety. The best time to swim with turtles in Zanzibar falls during the dry seasons, which are June to October and December to February. During these months, the sea is calmer, and the visibility is better for snorkelling and swimming.
The long rainy season from March to May can mean rougher seas and lower clarity, particularly along the east coast. However, turtle sanctuaries like Nungwi and Kizimkazi are still accessible, as they are in sheltered lagoons.
Where to visit Zanzibar: How to get to Zanzibar’s turtle swimming locations
Most travellers come to Zanzibar via Abeid Amani Karume International Airport or by ferry from Dar es Salaam. From Stone Town, the road network links to all major turtle sites. Nungwi and Kendwa are accessed by a paved road which leads to the north, and Kizimkazi is accessed by heading south through the central part of the island. Matemwe, the starting point for the Mnemba Atoll, is accessed by driving northeast from Stone Town.
Hotels, tour companies and dive centres throughout Zanzibar can organise travel and snorkelling trips, which make it quite simple to plan turtle encounters, even on a short visit.
A special marine experience to plan for
Swimming with turtles in Zanzibar is not only a tourist attraction but also an opportunity to interact with one of the most graceful animals of the Indian Ocean in a setting that combines conservation and natural beauty. Whether you choose the calm lagoon of Nungwi, the community sanctuary of Kizimkazi, or the wild reefs of Mnemba Atoll, each experience has something different and meaningful to offer. For those travelling to Tanzania’s islands, taking a turtle swim in Zanzibar is an added memorable, enriching dimension to any beach holiday, making it a destination that really stands out in East Africa.
