About One Ocean Diving Zanzibar
One Ocean Diving Zanzibar is the first and most established PADI 5 Star Dive Centre in Tanzania, with bases in Kendwa, Matemwe, and Stone Town. Since opening, the centre has built a reputation as the go-to operator for scuba diving and snorkeling excursions across the Zanzibar Archipelago, welcoming everyone from first-time snorkelers to experienced technical divers.
Their dive programme covers more than 30 sites around the island, including the world-famous Mnemba Atoll, wall dives off the northern coast, and wreck dives near Stone Town. They run the full range of PADI courses from Discover Scuba through to Divemaster, along with daily fun dives, guided snorkeling trips, Prison Island tours, and traditional dhow sunset cruises. Equipment is well-maintained and groups are kept small for a personal experience.
What sets One Ocean apart is their deep local knowledge — instructors and divemasters are long-term Zanzibar residents who know every reef intimately. Their multi-location setup means guests can dive from whichever coast suits the conditions, and their commitment to marine conservation and reef-safe practices has earned consistently top reviews from visitors year after year.
