Calabidongan Cave

Calabidongan Cave is a natural limestone cave system in Barangay Cotmon, Camalig, Albay, in the Bicol Region at the foothills of Mayon Volcano. It features stalactites, stalagmites, flowstones and a small underground stream. Developed as a community-managed eco-tourism attraction, it is explored with local guides and requires spelunking through narrow and slippery passages. The cave is noted for its geological formations and is part of Camalig's cave network alongside Hoyop-Hoyopan Cave.

Visitors can expect a guided spelunking experience through a natural limestone cave with low ceilings, narrow passages, stalactites and stalagmites, and damp, slippery floors with a shallow stream in sections. The approach involves a short trek from Barangay Cotmon through rural and hilly terrain. Inside, lighting is limited to headlamps and flashlights, and exploration involves crouching, wading and scrambling. The surroundings are agricultural and forested foothills of Mayon Volcano.
