Peleliu Corner
Blue Corner · Palau
Peleliu marks the southern tip of Palau's barrier reef, where Pacific Ocean and Philippine Sea currents collide over a submarine ridge between Peleliu and Angaur, generating some of the strongest flow in Palau. The dive traces the sheer Peleliu Wall, dropping past giant sea fans from a 10 m plateau near the World War II landing beach monument to a 30 m corner where Peleliu Cut and Peleliu Express merge. Divers set a reef hook at the lip and hold against the rip while grey reef sharks cruise the blue in groups of 15 or more, joined by whitetips, bumphead parrotfish, Napoleon wrasse, and schooling barracuda. Slack tide windows are short and the current can pull divers deep into the corner, so trips are timed to the tide tables. Sailfin snapper mass to spawn here from March through May.

For this site
- Reef hook · Currents are among the strongest in Palau and reverse at the tide change. Hooking into rubble at the 10 to 15 m lip is the only way to hold position and watch the shark line without finning hard.
- Surface marker buoy · Drift exits run out over open ocean off the corner, so operators require an SMB deployed on ascent for boat pickup.↗
