Zanzibar is one of the few places in the world where swimming with wild dolphins in the open ocean is a genuine, reliable experience — not a tourist gimmick. Here's everything you need to know before you go.
Every morning at Kizimkazi, on Zanzibar's southwest tip, wooden fishing boats head out into the Indian Ocean in search of spinner and bottlenose dolphins. On most days, they find them. The dolphins that inhabit these waters are wild, free-ranging, and remarkably tolerant of human company — making this one of the most accessible and authentic wildlife experiences in East Africa.
If you're staying at Protels La Plage in Bwejuu, Kizimkazi is approximately 30 minutes south by road. It's one of the most popular half-day excursions from the east coast, and for good reason.
The Dolphins of Kizimkazi
Two species are regularly spotted in the waters around Kizimkazi:
Spinner Dolphins
The more commonly spotted species. Known for their acrobatic leaping and spinning behaviour, they travel in large pods and are often seen close to the surface.
Bottlenose Dolphins
Larger and less numerous than spinners, but equally impressive in the water. They tend to be seen in smaller groups and are often more curious around boats.
Both species are resident in these waters year-round, which means dolphin watching at Kizimkazi is possible on any day of the year — unlike many wildlife experiences that are restricted to specific seasons.
What Actually Happens on the Tour
Tours typically depart early in the morning — usually between 7:00 and 8:00 AM — when the dolphins are most active and the water is at its calmest. The boat heads out from Kizimkazi harbour into open water, where the guide scans the surface for fins and splashing.
When a pod is spotted, the boat moves carefully into position. Guests are invited to slip quietly into the water with a mask and snorkel. The dolphins, accustomed to this interaction, often approach out of curiosity — sometimes swimming directly underneath or alongside snorkellers at close range.
The experience typically lasts two to three hours in total, including travel time from the harbour. Most guests return to the resort by mid-morning, leaving the rest of the day free.
"The dolphins swam directly underneath us — close enough to touch, though we didn't. It was the most extraordinary thing I've ever seen in the water."

Best Time of Day to Go
Early morning is universally agreed to be the best time for dolphin watching at Kizimkazi — and there are good reasons for this:
- Dolphins are most active and surface more frequently in the morning
- The water is calmer, making snorkelling easier and sightings clearer
- Fewer boats are on the water, meaning less disturbance to the pods
- The light is better for photography in the early hours
Afternoon tours do run and can still result in sightings, but morning departures give significantly better odds of a close encounter.
Best Time of Year
Dolphin watching at Kizimkazi is a year-round activity — the dolphins are resident and don't migrate. That said, conditions vary by season:
- June to October (dry season) — clearest water visibility, calmest seas, easiest snorkelling conditions
- December to February — warm, dry, and excellent conditions with good sightings
- March to May (long rains) — tours still run but sea conditions can be rougher; visibility may be reduced
Responsible Tourism Note
The best operators maintain a respectful distance from dolphin pods and avoid chasing or surrounding them. When booking through Protels La Plage, ask specifically about the operator's approach to wildlife interaction — responsible operators follow guidelines that protect the dolphins while still delivering an incredible experience.
What to Bring
- Swimwear — worn under your clothes for easy water entry
- Waterproof camera or GoPro — essential for capturing underwater encounters
- Sunscreen — reef-safe formula to protect the marine environment
- A light towel — the boat ride back can feel cool when wet
- Sea sickness medication if you're sensitive — the open water can be choppy
Snorkelling equipment (mask, fins, snorkel) is typically provided by the tour operator, but confirm this when booking.
Is It Suitable for Children?
Yes — dolphin watching at Kizimkazi is one of the best family activities in Zanzibar. Children who are comfortable in the water and can use a snorkel will get enormous enjoyment from it. For younger children or those who prefer to stay on the boat, the surface activity of the dolphins is often visible without getting in the water at all.
Most operators are experienced with family groups and will accommodate children's needs on the water.
How to Book from Protels La Plage
The easiest way to arrange a dolphin watching tour is directly through the resort's excursion team. They work with trusted local operators, handle transport from Bwejuu to Kizimkazi and back, and can advise on the best departure time based on current conditions. It takes one conversation at the front desk — usually the evening before — to have everything organised.
