An island barangay (village) under the jurisdiction of the municipality of Masinloc, Zambales, in northwestern Luzon. The reefs in the northeastern part of the island are fringing, characterized by a vast reef flat with sudden drop-offs in the crest. Spur and groove formation is common along the reef crest, particularly in the area facing the South China Sea. A 127-hectare fish sanctuary was established in 1989.
