Overview

Tortoises Meet Turquoise Sand

This full-day boat excursion pairs Zanzibar's two most photogenic offshore experiences: Prison Island, home to a famous colony of giant Aldabra tortoises and a shallow snorkelling reef, and Nakupenda Sandbank, a sliver of pure white sand that appears in the turquoise shallows south of Stone Town at low tide.

The day combines wildlife, snorkelling and one of Zanzibar's signature barefoot beach lunches, freshly grilled seafood served on the sand itself, making it one of the most complete and visually spectacular single days available on the island.

Two Islands, One Unforgettable Day

Prison Island (Changuu) sits in Zanzibar's harbour and is best known for its giant Aldabra tortoises, gifted from Seychelles in 1919, alongside the ruins of a 19th-century quarantine station and a shallow reef ideal for beginner snorkellers. Nakupenda Sandbank, whose name means 'I love you' in Swahili, lies a short boat ride further south and is a tidal sandbar that only fully emerges at low tide, disappearing again as the water rises.

Because Nakupenda is tide-dependent, departure times shift daily around the tide tables, and your Haven Trails guide manages timing so you experience both islands at their best: the tortoises and reef mid-morning, then a long, relaxed sandbank lunch and swim as the tide allows.

Why Book With Us

Why Haven Trails Adventures

01
Locally Based in Tanzania

Based in Moshi, Tanzania, not a booking platform abroad. Our Zanzibar partners are deeply embedded in the island's hospitality and activity networks, with real-time knowledge of the best guides, boats and conditions throughout the year.

02
Licensed, Vetted Guides

Every guide and boat operator working with Haven Trails is licensed by the Zanzibar Commission for Tourism and personally vetted for safety, professionalism and knowledge of the island's history, culture and marine environment.

03
Small Group & Private Options

Choose a small shared group departure or book the tour privately for your party alone. Either way, you get an unhurried, personal experience rather than being herded through a crowded, oversized tour bus itinerary.

04
24/7 Support Throughout

A Haven Trails ground team is reachable throughout your Zanzibar stay for any change, question or unexpected situation. You are never navigating the island alone from pickup to drop-off.

05
Responsible Travel

Haven Trails prioritises locally-owned operators, community guides and marine conservation partners. A portion of every booking supports coral reef protection and community tourism initiatives on the island.

06
Transparent, Fair Pricing

No hidden extras, no last-minute upsells at the dock. What you see at booking is what you pay, with clear notes on anything genuinely excluded, such as the Zanzibar marine park conservation fee.

FAQ

Common Questions

Why does the departure time change day to day?
Nakupenda Sandbank is a tidal feature that only fully appears at low tide, so Haven Trails schedules each departure around that day's tide tables to ensure the sandbank is visible and swimmable during your visit.
Is the seafood lunch really cooked on the sandbank?
Yes, a boat crew sets up a simple charcoal grill directly on the sand and cooks fresh fish, prawns and calamari to order, served with rice, salad and fruit, a genuine Zanzibar signature experience.
Can non-swimmers still enjoy this tour?
Yes, the water around Nakupenda is shallow enough to stand in for most of its area, and life jackets are available for anyone who prefers extra reassurance while wading or snorkelling.
What should I bring?
Swimwear, reef-safe sunscreen, a hat, a light coverup and a waterproof phone case if you want photos on the sandbank itself, since there is no shade structure on Nakupenda.
Is this better than the Prison Island & Stone Town tour?
It depends on your interests: this option is better for beach lovers who want swimming and a signature lunch, while the Stone Town combination suits travellers more interested in history and architecture.
