If you are planning to snorkel in Zanzibar, you have probably heard the name Menai Bay mentioned more than once. It is the protected stretch of ocean on the southwest coast of Unguja, and it is widely considered one of the most reliable snorkeling areas on the island.
But what is it actually like underwater? What fish will you see? When is the water clearest? And what should you know before you jump in?
This guide answers all of that, based on our own years of sailing and snorkeling in these waters every week.
Where Is Menai Bay?
Menai Bay sits on the southwest coast of Zanzibar's main island, Unguja. The bay is a designated marine conservation area, which means fishing is regulated, coral is protected, and the entire underwater ecosystem is managed to keep it healthy.
All dhow safaris that depart from Fumba Village sail into Menai Bay. It is the natural starting point — Fumba sits right at the northern edge of the bay, and the local captains have been navigating these waters for generations.
Why Snorkel in Menai Bay?
Not all snorkeling areas in Zanzibar are equal. Menai Bay has several advantages:
- Protected water. The bay is sheltered from the open ocean, so the water is often calmer than at exposed reefs elsewhere on the island.
- Healthy coral. Because fishing and anchoring are regulated, the reefs have been allowed to recover and thrive.
- Reliable visibility. Depending on the season, underwater visibility can range from 10 metres to 25 metres.
- Variety of sites. The bay contains several distinct reef systems and shallow coral gardens, suitable for different skill levels.
- Close to the sandbank and Kwale Island. Snorkeling is only one part of the day — you can combine it with a sandbank stop and a visit to Kwale Island.
What You Will See Underwater
The reefs inside Menai Bay are home to a wide range of tropical marine life. Here are the species you are most likely to spot on a typical snorkeling stop.
| Marine Life | What to Look For |
|---|---|
| Parrotfish | Large, colorful fish in shades of turquoise, green, and pink. Often heard before they are seen — they crunch on coral. |
| Angelfish | Elegant, slow-moving fish with striking patterns of yellow, blue, and black. Common around coral heads. |
| Butterflyfish | Small, brightly-colored fish with thin, disc-shaped bodies. Often seen in pairs. |
| Sergeant Major | Small silver-and-black striped fish. Very common in shallow water — one of the first fish most snorkelers notice. |
| Clownfish | Orange and white, living among anemones. Less common here than in the Red Sea, but still seen. |
| Moray eels | Long, snake-like fish that hide in coral crevices. Look, but do not reach in — they can bite if threatened. |
| Triggerfish | Bold, colorful fish with strong jaws. Beautiful — but keep a respectful distance during nesting season. |
| Sea turtles | Occasionally seen grazing on seagrass. If you spot one, remain still and let it come and go on its own. |
| Octopus | Masters of camouflage. Rarely seen unless you know exactly where to look — but our crew knows the spots. |
| Stingrays | Sometimes seen gliding over the sand near the reef edges. Watch from above — never step on them. |
Water Conditions — What to Expect
Water temperature in Menai Bay stays warm throughout the year, so most visitors snorkel comfortably without a wetsuit. Underwater visibility is best during the dry seasons (June–October and December–February), when the sea is calm and the water is at its clearest.
During the long rains (April–May), visibility drops and the sea becomes choppier. Many operators, including ours, reduce their schedule during this period.
What to Bring for Snorkeling
You do not need specialist equipment. On our tours, we provide:
- Snorkeling mask — in multiple sizes
- Fins — in multiple sizes
- Life jackets — for all ages, including children
- Safety briefing — before entering the water
We recommend you bring:
- Reef-safe sunscreen — never use regular sunscreen near coral
- Rash vest or t-shirt — for protection from the sun on your back
- Waterproof phone pouch — if you want photos underwater
- Antifog drops for the mask (optional — some crew provide this)
Is It Safe for Beginners?
Yes. Menai Bay is a good snorkeling location for beginners because:
- The water is relatively calm inside the bay
- Snorkeling happens in shallow water (1–4 metres)
- Life jackets are provided for everyone
- Our crew stays in the water with guests and keeps watch
Non-swimmers are also welcome. The crew assists guests who are not confident in the water, and many of our first-time snorkelers end up loving it.
Snorkeling Etiquette — Protecting the Reef
Menai Bay is a conservation area. Every visitor has a role in keeping it healthy for the next traveler. Please follow these simple rules:
- Do not touch the coral. Coral is a living animal. Touching it damages it — sometimes fatally.
- Do not stand on the reef. Use your fins to float, not your feet to push off.
- Do not chase marine life. Let fish, turtles, and dolphins come to you.
- Do not feed the fish. It changes their natural behavior and harms the reef.
- Use reef-safe sunscreen. Common sunscreen ingredients bleach coral.
- Do not collect shells, coral, or sand. Take only photos, leave only bubbles.
Combining Snorkeling With the Rest of the Day
On a typical dhow safari from Fumba Village, the snorkeling stop is only one part of the day. The itinerary usually looks like this:
- Morning: Depart Fumba and sail into the bay, with an early snorkeling stop at a coral reef.
- Midday: Stop at the sandbank (sometimes called the "Blue Lagoon") for swimming and photos.
- Lunch: Arrive at Kwale Island for a fresh seafood BBQ on the beach.
- Afternoon: Sail back to Fumba, with the option of a second snorkeling stop in calmer water.
Guests who want more time in the water can ask their captain to extend the snorkeling stop — the pacing is one of the advantages of a smaller, local crew.

No. Life jackets are provided, and our crew assists non-swimmers. Many guests snorkel comfortably for the first time on our tours.
What if I have never snorkeled before?
You will be given a short briefing before entering the water, and the crew is nearby the entire time. The water inside the bay is calm and shallow, which makes it beginner-friendly.
Can I bring my own snorkeling gear?
Yes. If you have a mask and fins you already trust, feel free to bring them. We also provide gear at no extra cost.
How long does the snorkeling stop last?
Typically 30–45 minutes at the main reef stop. Depending on conditions and guest preferences, the captain may add a second snorkeling stop later in the day.
Is snorkeling included in the tour price?
Yes. Snorkeling gear, life jackets, and the snorkeling stop itself are included in our all-inclusive tour price of $85 per person.
What is the best time of day to snorkel?

Menai Bay is one of Zanzibar's quiet treasures. It does not have the crowds of some northern beaches, but it has something better — calm water, healthy reefs, and a marine environment that has been protected for decades.
Whether you are an experienced snorkeler or trying it for the first time, the reefs here are worth the trip. Come respectfully, follow the conservation rules, and the bay will reward you.
