Why dive here
With 382+ marine species recorded in the area - including blue sharks, eagle rays, giant moray eels, humpback whales and sperm whales - Arch offers some of Kadavu & Great Astrolabe Reef's richest cave diving.
The Arch, a straightforward cave dive in Kadavu, is a good spot for newer divers looking to explore overhead environments. Dropping to about 20 meters, you navigate through a series of openings, often seeing schools of small reef fish sheltering inside. It’s less about big pelagics here and more about the structure itself, the light filtering in, and the occasional whitetip reef shark cruising past the entrance. We'd suggest going in the morning; the sun angle really makes the inner sections glow.
