Poro Island (Filipino: Poro Isla) is an island in the province of Cebu, located east of Cebu Island and west of Leyte Island. Two municipalities, Poro and Tudela, are located on Poro Island. It is one of the four Camotes Islands along with Pacijan Island, Ponson Island, and Tulang Island. The island is one of the early Pacific contact sites between the East and the West.
The island has various caves. One is the Bukilat Cave, which is a large natural cavern in the southeastern part of the island. Because of naturally formed piercings in its canopy, the interior is well-illuminated. There are many stalactite and stalagmite formations in the cave. It was used as a shelter for Poro Island residents during the Japanese occupation of the Philippines during World War II.
Busay and Pangunuron Falls are among the waterfalls on the island.
Buho Rock is a hole in a cliff wall said to have been formed when a Spanish warship mistook it for an enemy ship in the mist and fired cannon into it. It is reached by a stone staircase and offers views of Poro and the sea.
The Poro islands are home to the Porohanon language, one of the most endangered languages in the Visayas. The language is only used on Poro island. The language is classified as distinct from Cebuano (Bisaya) by the Komisyon ng Wikang Filipino and is vital to the culture and arts of the Porohanon people.
