New Drop Offs - Rock Islands
New Drop Offs gives you a classic Palau wall dive, dropping to over 40 metres. We often see reef sharks patrolling the edge, and the occasional manta ray cruises by in the blue. Keep an eye out for schooling jacks and barracuda, too. It’s a good spot for divers comfortable with depth and currents, offering consistent big animal encounters.
