Alcatraz is a boat-access reef circling a lone rocky islet in the channel between Busuanga and Coron Island. Coral growth covers the reef and the site is known for schooling fish moving through the channel, along with nudibranchs and other small reef life around the slopes, overhangs, and pockets in the rock. Conditions can change quickly with the tide, so the dive is best planned around current and sea state.
