One Ocean at Zanzibar Pearl Boutique Hotel

One Ocean is situated within the Zanzibar Pearl Boutique Hotel & Villas, a property set across 39,000 m² of tropical gardens in Matemwe. This location on the northeast coast of Zanzibar provides a tranquil base for divers looking to explore the local archipelago.

The centre operates with a focus on the natural environment, providing easy access to the reef and the famous Mnemba Atoll. Because it is integrated with a boutique hotel, you can transition from the dive boat directly to the hotel's pool or beach facilities.

The centre operates as an independent diving school with a staff described as friendly and attentive to detail. While the specific number of instructors is not listed, the service is designed to be personal and professional.

All communications and dive operations are conducted in English. The team manages excursions that typically last between five and six hours, with departures scheduled in the morning to align with local conditions.

The waters around Mnemba Atoll are a hub for large pelagics and resident marine life. You will frequently encounter Bottlenose dolphin (Delphinidae) and various species of turtles, including the Green sea turtle (Chelonia mydas). Schools of fish such as Fusilier (Caesio), Snapper (Lutjanus), and various tropical fish fill the water column.

The reef structure is home to a wide array of colourful reef fish, including Butterflyfish (Chaetodon), Angelfish (Pomacanthidae), and Surgeonfish (Acanthuridae). You can also spot Moorish idols, Parrotfish (Calotomus), and various species of Triggerfish (Balistidae) navigating the coral.

For those interested in macro life, the area hosts a diverse range of smaller organisms. Look for Seahorse (Hippocampus kuda), Ghost pipefish (Solenostomidae), and various species of Octopus (Octopus vulgaris). The seabed and crevices are also likely to hold Nudibranch (Chromodoris willani), Scorpionfish (Scorpaenidae), and various species of shrimp and porcelain crabs.

Diving schedules and trip durations are heavily influenced by the local tides and sea conditions. Boat departures are timed between 8:00 a.m. and 11:00 a.m. to make the most of the morning window, with return times varying between 13:30 and 15:30 depending on the swell and tide.
