Mnemba Island Snorkeling, Stone Town & Prison Island

Experience Zanzibar’s Best in One Day: Snorkeling, History & Giant Tortoises

Whether you’re looking for vibrant underwater life, a stroll through historic streets, or a chance to meet gentle giant tortoises, this experience offers a well-rounded taste of the island’s charm.

What makes this tour stand out is its combination of adventure, culture, and wildlife. We particularly love the opportunity to snorkel among coral reefs teeming with fish and possibly dolphins, the engaging guided walk through Stone Town’s labyrinth of alleys, and the chance to interact with giant tortoises on Prison Island.

A Day of Adventure and Discovery in Zanzibar

Let’s break down what a typical day on this tour would look like, and why each stop offers something special.

Starting with Snorkeling at Mnemba Island

The day begins early, with hotel pickup arranged by Zanmiracles Zanzibar Travel and Safaris. The boat ride to Mnemba Island is approximately an hour, and you’ll appreciate the chance to relax and soak in the ocean views. The boat itself is a comfortable vessel, often carrying small groups, which keeps the experience intimate.

Mnemba Atoll is renowned for its vibrant coral reefs, which host an abundance of colorful fish and marine life. Snorkeling here is the absolute highlight — the waters are clear, warm, and inviting. Many reviews mention the chance to see dolphins, with one reviewer noting “dolphins playing nearby while we snorkeled,” adding a magical element to the morning.

The snorkeling gear provided is generally good quality, and the guides are attentive, making sure everyone is comfortable in the water. Some travelers bring their own masks and fins for a better fit, but the provided equipment is sufficient for most. Snacks and fresh fruit are served on board, giving you a quick energy boost before moving on.

Tip: If you’re prone to seasickness, take precautions, as the boat ride can be choppy depending on weather conditions.

Exploring Stone Town with a Local Guide

After your marine adventure, the tour heads to Zanzibar’s historic heart — Stone Town. This UNESCO World Heritage site is a treasure trove of history, architecture, and lively local markets. The guided walk is a real highlight, with knowledgeable guides sharing stories about the city’s diverse background.

Expect to wander through narrow alleys, passing by centuries-old doors, bustling markets, and historic landmarks like the Old Fort and the House of Wonders. The former slave market site is a sobering reminder of Zanzibar’s complex past, thoughtfully woven into the narrative by your guide.

Guests consistently praise the guides for their local knowledge and engaging storytelling, often quoting that they “learned so much about Zanzibar’s culture and history.” The walk provides a genuine sense of place, with opportunities to browse local crafts and perhaps buy a few souvenirs.

Pro Tip: Wear comfortable walking shoes and bring your camera — the architecture and street scenes are picture-perfect.

Visiting Prison Island and Its Giant Tortoises

The final stop is Prison Island, a short boat ride from Stone Town. Originally built as a detention center, it now serves as a sanctuary for giant Aldabra tortoises. This part of the tour offers a charming, relaxed atmosphere that appeals especially to animal lovers.

On arrival, you’re free to feed and photograph these gentle giants, some of whom are over a hundred years old. The island’s dark past as a prison is touched upon by your guide, adding context to the visit.

Reviews highlight the memorable experience of interacting with the tortoises, describing them as “adorably slow and surprisingly friendly.” You might also explore the island’s small museum or relax on the beach before heading back.

Note: The visit to Prison Island is generally quick, but enough time is allocated to enjoy feeding tortoises and taking photos.
