The short answer is: yes, in many places — but with caution. Like many natural environments around the world, the waters in Tanzania come with both delights and dangers. Whether you’re heading for the Indian Ocean or planning to cool off in a freshwater lake or river, here’s what you need to know.
1. Swimming in the Ocean: Mostly Safe, But Watch the Tides
Tanzania’s Indian Ocean coast is stunning — warm, clear, and full of marine life. Zanzibar, Pemba, Mafia Island, and the mainland beaches like Pangani and Bagamoyo offer safe and enjoyable swimming conditions in designated areas. Resorts and popular beaches are generally monitored, and the waters are free from large predators like sharks.
But there are two key things to be aware of:
-
Tides and currents: Some beaches, especially on Zanzibar’s east coast, experience strong tides and undercurrents. It’s important to ask locals or your accommodation staff about safe swimming times and areas.
-
Sea urchins and coral: Wear water shoes if you’re exploring rocky areas, as sea urchins can deliver painful stings. Be mindful not to damage coral reefs, which are protected.
2. Lakes: Beautiful but Choose Wisely
Tanzania is home to some of the largest and deepest lakes in Africa, such as Lake Tanganyika, Lake Victoria, and Lake Nyasa (Malawi). While these lakes offer calm, warm waters, not all are equally safe for swimming.
-
Lake Tanganyika is often considered one of the safest freshwater bodies to swim in — especially in tourist-friendly areas like Kigoma. The water is clear and deep, and bilharzia (a parasitic disease common in stagnant or slow-moving freshwater) is not prevalent in most of the lake.
-
Lake Victoria, however, is more problematic. It has a high risk of bilharzia, and in some areas, crocodiles and hippos pose serious dangers. It’s best to avoid swimming here unless you’re in a clearly designated and monitored area.
-
Lake Nyasa (Lake Malawi) has spots where people swim safely, particularly near lodges that routinely monitor water quality, but bilharzia risk remains.
-
Lake Duluti, near Arusha, is another beautiful crater lake that appears safe for swimming in terms of water quality. However, swimming is prohibited by local authorities to avoid disrupting traditional fishing and community activities. Visitors are encouraged to enjoy the lake by canoe or guided nature walks instead — it’s a chance to respect local customs and protect the ecosystem.
3. Chemka Hot Springs: A Hidden Gem with a Twist
Nestled near Moshi, Chemka Hot Springs (also known as Kikuletwa Hot Springs) is a stunning oasis featuring crystal-clear, turquoise waters surrounded by lush vegetation. The springs are fed by geothermal activity, maintaining a comfortable temperature of around 27°C (81°F), making it an ideal spot for swimming and relaxation.
Key details:
-
Depth and currents: The springs can be quite deep, reaching up to 10 meters in some areas. While the water is inviting, the currents can be strong, so it’s recommended for confident swimmers.
-
Entrance fee: The entry fee varies depending on the source, ranging from 10,000 to 25,000 Tanzanian Shillings per person.
-
Opening hours: Chemka Hot Springs are open daily from 8:00 AM to 6:30 PM.
-
Amenities: Visitors can rent floating buoys (made from tires) for approximately 10,000 TZS per day. Local youths often offer informal swimming lessons and demonstrate diving techniques. Additionally, small fish in the springs provide a natural pedicure by nibbling on dead skin.
4. Kideghe Waterfall: Seasonal Beauty in Shagayu Forest
Located near Uvi House & Restaurant in the Shagayu Forest, Kideghe Waterfall is a serene spot that becomes particularly inviting during the rainy season when water levels rise. The pool at the base of the waterfall is suitable for swimming, though the water is notably cold. It’s a refreshing experience for those prepared for the chill and looking to connect with nature in a tranquil setting.
5. Rivers and Waterfalls: Not Always Safe
Tanzania’s rivers and waterfalls are gorgeous, but they can be risky for swimming. Fast currents, unknown depths, and wildlife like crocodiles (especially in rivers near national parks) can make them dangerous. If a local guide or lodge says “don’t swim,” take their advice seriously. Always swim only in designated and trusted areas.
6. Swimming Pools: The Easiest Safe Option
For guaranteed safety and cleanliness, swimming pools at lodges and guesthouses are a great option. Many accommodations, even in remote areas, offer pools — and they’re especially welcome during the hot months.
7. General Safety Tips for Swimming in Tanzania
-
Ask locals or guides: Never assume a body of water is safe just because it looks inviting.
-
Be cautious at night: Avoid swimming in the ocean or lakes after dark, when visibility is poor and emergency help is harder to access.
-
Travel insurance: Always make sure your travel insurance covers water activities.
-
Stay hydrated and avoid alcohol before swimming, especially in hot weather.
In Conclusion: Yes, You Can Swim — Just Be Smart About It
Swimming in Tanzania is not only possible, it can be one of the highlights of your trip — from floating in turquoise ocean lagoons to snorkeling in protected marine parks. But like any travel experience, being informed is key to staying safe. Respect the environment, seek local advice, and always prioritize safety over spontaneity.
So pack that swimsuit — but also pack some common sense!
