Hoyop-Hoyopan Cave

Hoyop-Hoyopan Cave is a natural limestone cave located in Barangay Cotmon, Camalig, Albay, at the foothills of Mayon Volcano in the Bicol Region. Known for its wind-blown entrance and extensive chambers filled with stalactites and stalagmites, the cave is a protected natural attraction managed by the local government. It is notable for its geological formations, cool interior, and historical use as a refuge during World War II.

Visitors can expect a guided walk through a multi-chamber limestone cave with stalactites, stalagmites, columns and draperies, cool and humid interior, uneven rocky floors and low passages in places. The site has a developed entrance, concrete pathways and lighting in main chambers, surrounded by rural landscape and coconut groves at the base of Mayon Volcano. Guides explain rock formations and cave history during the tour.

The cave served as a natural refuge and shelter for local residents and guerrillas during the Japanese occupation in World War II. It was later developed and conserved as an ecotourism attraction by the Municipality of Camalig.

The name Hoyop-Hoyopan derives from the Bikol word 'hoyop' meaning to blow, referring to the wind currents felt at the cave entrance. The cave is regarded locally as a natural heritage feature of the Mayon Volcano landscape and is promoted as a community-based ecotourism site.
