Pulo Island, commonly known as Isla Pulo, is a long, narrow island surrounded by mudflats in the Manila Bay coast of Navotas, about 13 kilometers (8.1 mi) north of Manila in the Philippines. It is a sitio in Barangay Tanza, connected to the mainland of Navotas by a 500-meter-long (1,600 ft) bamboo bridge. The island is known for its mangroves for which it was declared a "marine tree park" and as one of four ecotourism sites in Metro Manila established under the National Ecotourism Strategy in 1999. In 2014, it was home to a resettlement site of about 137 indigent families that mostly occupied the island's southern tip.
