Site details

Amber's Arches is a Kauai south-shore boat dive with a reef plateau, drop-off, arch/ledge features, holes, and undercut structure. It is attractive for eels, lobsters, dark-loving fish, reef sharks, and occasional rare finds such as longnose hawkfish in black coral. Treat the arch and hole features as swim-throughs, not caves for untrained penetration.
