Swimming With Dolphins in Zanzibar: A Responsible Approach

Seeing wild dolphins in the Indian Ocean is a memorable experience, and dolphin trips from Kizimkazi in southern Zanzibar are among the island's most widely advertised excursions. They also provide important income for local boat captains and fishing families.

At the same time, researchers and conservationists have raised serious concerns about how some of these trips operate. We believe travelers deserve an honest picture so they can make an informed choice.

Which Dolphins Live Here

The waters off southern Zanzibar, including the Menai Bay area, are home to resident populations of Indo-Pacific bottlenose dolphins and Indian Ocean humpback dolphins. Spinner dolphins are also seen in the region. These are wild animals that feed, rest, socialize and raise calves in these waters, which is exactly why how we behave around them matters.

The Welfare Concerns

On busy mornings, many boats may head out at once and converge on the same pod. Some captains drive at speed toward the dolphins and drop swimmers directly in their path. Studies of similar tourism elsewhere suggest that this kind of repeated, intense disturbance can interrupt resting and feeding and may affect the animals' behavior over time.

In-water encounters are particularly sensitive. When dozens of snorkelers jump in near a pod, the dolphins usually simply swim away. A good encounter is one where the dolphins choose to stay, not one where they are chased.

Should You Go?

This is a personal decision. Some travelers choose to skip dolphin trips entirely and spend their time on reef snorkeling or conservation-focused excursions instead. Others go but insist on watching from the boat only. If you do decide to go, your choices as a customer can encourage better practices, as operators respond to what guests ask for.

How to Choose a Responsible Trip

Before booking, it is worth asking a few direct questions:

• Ask the operator how they approach pods and whether they limit time and boat numbers.
• Choose operators who do not chase dolphins or cut across their path.
• Prefer trips where watching from the boat is the default and swimming is optional.
• Look for operators who brief guests on conduct before departure.
• Consider a smaller, private boat rather than a large group trip.

Your Conduct on the Water

If dolphins approach, enjoy the moment quietly. Never try to touch, feed or follow them, and do not swim toward a pod or between a mother and calf. If you are in the water, enter gently from the side of the boat rather than jumping, and stay calm and still. Ask your captain to slow down and keep a respectful distance, and to leave if other boats begin to crowd the animals.

Remember that sightings are never guaranteed. A trip without dolphins is still a beautiful morning on the ocean.

When we arrange marine excursions for our guests, we brief them on these points in advance and favor captains who take a patient, low-impact approach. Small changes in how each boat behaves add up, and they help ensure these dolphins remain in the bay for future visitors and local families alike.
