Great Santa Cruz Island is a small inhabited island in Zamboanga City in the southern region of the Philippines that is famous for its pink coralline sand. The island, located 4 km (2.49 mi) south of downtown at the Santa Cruz Bank in the Basilan Strait, boasts the only pink sand beach in the Philippines. The color of the sand comes from the pulverized red organ pipe coral from eons of surf erosion mixed with the white sand.
