Arch - Kadavu & Great Astrolabe Reef
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.
