Briefing your divemaster on down current procedures before entering is not optional here, as down currents can develop quickly with little warning along the wall face. Boat traffic in the channel is active, so surface marker buoy deployment at the end of the dive is essential.
Daily dive trips are available from Neco Marine located on Main St at the start of Malakal Island in Koror.
