help Great Sea Reef FAQ
Where is Fiji's Great Sea Reef located?
The Great Sea Reef, or Cakaulevu, runs along the northern side of Vanua Levu and nearby islands in Fiji. The system extends for roughly 200 kilometers through reefs, channels, seagrass areas, and mangrove-linked habitats.
What marine animals live around the Great Sea Reef?
Its connected habitats support reef fish, sea turtles, sharks, rays, and many coral species. Mangroves and seagrass beds also provide nursery and feeding areas for animals that later move onto the reef.
Can visitors dive or snorkel at the Great Sea Reef?
Yes, diving and snorkeling are available from parts of northern Fiji, including areas reached through Vanua Levu. The reef is extensive and remote, so access depends on the chosen resort or specialist boat operator rather than a single public entry point.
What threatens the Great Sea Reef?
Threats include coral bleaching, destructive or excessive fishing, sediment runoff, and damage to mangrove and coastal habitats. Climate-driven ocean warming is especially serious because Fiji's corals can bleach during sustained heat stress.
