Dan yr Ogof, Show cave system in Powys, Wales
Dan yr Ogof is a show cave system in Powys stretching through roughly 17 kilometers of limestone passages, with three major cave sections joined by underground tunnels and dotted with subterranean lakes. The complex is managed as a commercial attraction where visitors can explore lower-level passages on guided tours.
Three Morgan brothers initiated the first exploration of the cave system in 1912 using basic equipment, paddling across underground lakes on simple rafts. This early expedition eventually led to the site's development as a scientific research location and later as a public attraction.
The Welsh name means 'Beneath the Cave', a reference to the Morgan family farm where locals first found the entrance.
The center operates seasonally from March through October, with standard tours guiding visitors through the accessible lower passages. Those interested in exploring deeper into the cave system should look for specialized caving experiences led by trained professionals.
Archaeological digs in lower chambers revealed bones from roughly 42 people alongside animal remains, showing the cave was home to prehistoric inhabitants. These findings rank among the most important evidence for early human settlement in Wales, demonstrating repeated use across many thousands of years.
