One of many cave systems in Brecon Beacons National Park, the Dan-yr-Ogof Caves are an 11-mile (17km) cave complex located about 15 miles (24km) southwest of Brecon. Only the first portion of the system is open to the public, but the spectacular limestone rock formations of the three available caves, the Dan yr Ogof Showcave, the Cathedral Showcave and the Bone Cave, should not be missed. Formed 315 million years ago, the formations include vertical stalactites and stalagmites, and also rare helectites, which grow sideways. The Bone Cave is named for the 42 human skeletons that have so far been discovered in the chamber. Many of the skeletons date back to the Bronze Age, more than 3,000 years ago. The cave now contains some award-winning exhibits on humankind's cave-dwelling history.
The National Showcaves Centre for Wales also has a dinosaur park with more than 50 life-size statues; an Iron Age farm with a replica village; a Victorian farm where kids can interact with numerous domestic animals; the Shire Horse Centre; an adventure playground which will delight kids; and replicas of some of the famous stone circles found in Wales. All these attractions, the caves, and a museum are covered by the admission fee.
