Ogof y Daren Cilau, Limestone cave system in Mynydd Llangatwg, Wales.
The cave system extends over 28 kilometers through limestone passages and contains substantial underground chambers with numerous mineral formations and geological features.
Discovered in 1957 by Vic Howells from British Nylon Spinners Caving Club, the cave system underwent major exploration phases leading to significant discoveries in 1984.
The cave holds multiple established underground camps, including one named 'Restaurant at the End of the Universe' located thirteen hours from the entrance.
The entrance requires navigating through a demanding 517-meter crawl space, which functions as a natural deterrent to inexperienced visitors.
The Time Machine section represents the largest cave passage in Britain, while the White Company features pure white stalactites formations.
