This natural channel forms a perfect westerly corridor between two Islands and is washed with flooding or ebbing current every six hours as the sea water rushes in and out again of Puerto Galera Harbour and its various small bays and inlets.

Green Sea Turtles and Rays often drift through the channel, idly following the current as they search for new feeding grounds. Up in the shallows on the interior of the Northern slopes can be found huge colonies of awesome hard corals and small reef fishes in schools and further out towards the open sea there are several ledges and overhead environs that support large Sponges, Gorgonian Fans, and Oyster Clams. A myriad of macro subjects are usually found on this dive. Currents are minimal.
