One Ocean - The Zanzibar Dive Centre

One Ocean is Zanzibar's premier PADI 5-Star dive centre, operating from the historic Stone Town waterfront. The centre accesses dive sites along Zanzibar's west coast, where coral reefs fringe the coastline and offshore pinnacles and walls provide diverse diving for all experience levels.

Zanzibar's dive sites feature healthy hard and soft coral gardens with resident green and hawksbill turtles, white-tip reef sharks, octopus, and a kaleidoscope of Indian Ocean reef fish. The deeper offshore sites host larger pelagic visitors including eagle rays, barracuda, and bottlenose dolphins. The centre also runs trips to Mnemba Atoll on the northeast coast — a pristine marine conservation area with stunning wall dives and regular dolphin encounters.

With PADI and SSI certifications available in English, Swahili, and Italian, the centre caters to Zanzibar's diverse visitor base. Water temperature stays 25-30°C year-round, and the best diving conditions are October-March and June-October with visibility reaching 20-40 metres.
