Ulong Channel

Ulong Channel is Palau's premier drift dive — a long passage through the outer reef where the incoming tide funnels water with enough force to carry divers effortlessly over a reef floor covered in pristine hard corals and swarming with every species the surrounding ocean can produce. Grey reef sharks, white tip sharks, and tawny nurse sharks rest on the sandy channel bottom while above them pass schools of snapper, fusiliers, and trevally in their thousands. The channel is designed by geology for drift diving: its walls act as guides and the exit delivers divers to an outer reef slope where eagle rays and occasionally oceanic mantas cruise past. It runs best on a flooding tide and the experience changes completely depending on current strength.
