A Tumbatu Island snorkeling tour is the answer for anyone who did Mnemba and left disappointed by the boat traffic. Tumbatu lies about two kilometres off the north-west coast, its coral is in better shape than the famous atoll's, and this listing caps the boat at eight people. Four hours, $71, tips included — and no sandbank, no BBQ, no theatre.

Quick answer
A four-hour half day from the north coast for $71: a bottlenose dolphin swim off Nungwi and snorkeling over the coral gardens at Tumbatu Island, with a hard cap of eight participants and pickup from five north-coast beaches. Tips are included, which almost no listing on the island does.
Key takeaways
- All snorkeling in Zanzibar tours compared — six trips, four reefs, prices from $41 before fees
- Tumbatu's coral is in better condition than Mnemba's and sees a fraction of the boats. Why
- Eight people maximum — the smallest boat in this catalog
- Same operator as the $55 Kendwa Mnemba trip, so the crew culture carries over
- Reviewers describe the crew reversing the order — snorkel first, dolphins later — when boats crowded the pod
- No sandbank and no lunch. This is a reef-and-water trip, not a day out
Why Tumbatu Instead of Mnemba
Two kilometres of water separate a famous reef from a quiet one, and the difference is mostly other people.
The reef
Tumbatu sits roughly two kilometres off the coast near Nungwi, and most boats actually work the coral around Mwana wa Mwana, the islet off its northern tip that separates from the main island at high tide. The coral gardens there are better preserved than Mnemba's, and the marine life is more interesting for anyone who has already ticked off the sergeant-major wall: batfish, ribbon eels, leaf fish, nudibranchs, pipefish and juvenile sweetlips.
The operator's own description leans on exactly this — untouched corals, uncrowded water, good visibility — and the trip is sold as the alternative for travellers who want peace rather than the famous name.
The honest counterweight
This is a small operation and the reviews carry criticism as well as praise. The listing's own summary records that some travellers found the snorkeling limited and would have preferred a richer site.
The fairest line comes from Jason, United States, 4 August 2026: "swimming with the dolphins was amazing but don't expect to see a lot in the coral, much like most of the world coral reefs are struggling everywhere." That is true of Zanzibar generally, not just this trip, and it is the right expectation to arrive with. What the reefs are really like.
How this crew handles the dolphins
The trip includes a bottlenose dolphin swim off Nungwi, and the operator is the same company that runs the Kendwa Mnemba trip, where reviewers repeatedly describe guides refusing to join the chase.
The pattern repeats here in specific terms. Jennifer from Qatar, 5 August 2026: her group said they were not comfortable chasing the pod through a crowd of boats, and the crew simply inverted the itinerary — snorkel first, dolphins later, once the fleet had moved on. Mathilda from Germany, 8 August 2026, described the same reversal on a morning when no dolphins showed early. Alvin from Italy, 9 August 2026, wrote about being the only boat in the area and never reaching Tumbatu at all because the pod appeared first.
A crew that will change the running order is the whole test. The dolphin question in full.
Cost, and the do-it-yourself alternative
From Nungwi you can arrange a local boat to Tumbatu for under $15. That is the honest comparison, and it is genuinely an option if you have your own mask, can negotiate on a beach and accept no schedule, no kit and no recourse.
What $71 adds: pickup from five beaches, a capped group of eight, equipment, water, fruit, guides who work in English and French, tips already covered, and free cancellation. On a coast where rental gear is famously poor, the mask alone can decide the morning. Tour versus doing it yourself.
Questions About This Trip
Is Tumbatu better than Mnemba for snorkeling?
For coral condition and quiet, generally yes — Tumbatu's reef is healthier and a fraction of the boats go there. For sheer quantity of fish and the classic Zanzibar photograph, Mnemba still wins. Reviewers of this trip also note the coral is patchy in places, which is true across the archipelago. The reefs compared.
How small is the group really?
The listing states a limit of eight participants, the smallest cap in this catalog. Pickup is from Kendwa, Nungwi, Kiwengwa, Matemwe or Pwani Mchangani, so the boat fills from the north coast only.
Are tips included?
Yes — tips and gratuity appear in the inclusions, which is rare in Zanzibar, where crews normally expect $3 to $5 per person on a half day. The rest of the fee stack.
Do I need to know about Tumbatu's culture?
Yes. The island's residents are conservative Muslims. Beachwear stays on the boat, you do not wander into the village dressed for the beach, and you ask before photographing anyone. The snorkeling happens offshore, so this mostly matters if the boat lands.
Who cannot book it?
The operator lists it as unsuitable for pregnant travellers, people with back problems, heart problems or high blood pressure, and travellers over 70. Currents on this side are stronger than at sheltered Mnemba.
What Travellers Said
In the morning there were many boats crowding the dolphins and we expressed that we were not comfortable chasing them so they adapted the tour to snorkel first and then find the dolphins later. This made it a lot more environmentally aware.
Swimming with the dolphins was amazing but don't expect to see a lot in the coral, much like most of the world coral reefs are struggling everywhere.
We especially liked that we didn't chase the dolphins with the crowds, but were able to swim with dolphins all alone, far away from the other boats. The guides were very respectful of the wildlife.
