Exploring The Astrolabe Reef

Kadavu Island is best known for the Great Astrolabe Reef.

The Astrolabe Reef runs along Kadavu’s southern shore then arcs north-east passed Ono Island up to Buliya Island – famous for manta ray snorkelling.

Named after the French ship Astrolabe, the Great Astrolabe Reef, is a breeding ground for big fish like tuna, marlin, giant trevally and sharks. Gaps in the reef can be subject to strong currents, but these also bring in the nutrients which feed everyone along the food chain, from the soft corals, to the reef fish, to the big fish. 

The environment makes for adventurous and colourful diving, with sites like Naiqoro Passage where you can experience big fish action against a background of colourful soft coral coated walls. But Kadavu has plenty of gentler sites too offering encounters with mantas and other pelagics in shallower, sheltered waters around the islands of Ono and Buliya. 

Kadavu’s resorts with on-site dive centres are dotted around the island, each having access to a range of dive sites from the 63m long Pacific Voyager Wreck, to the Muto Marine Protected area and the Great Astrolabe Reef. Many of the resorts’ fringing reefs are easily snorkelled too. The remoteness of Kadavu means that resorts are run sustainably, with Eco-friendly, yet comfortable (and sometimes luxurious) facilities, and you can expect that much of what’s served on your plate has come from a local garden.
