The river Llynfell emerges from the mountain as you approach the entrance to Dan-yr-Ogof, returning to the surface after an underground journey of more than 6km. It was by way of this entrance that the Morgan Brothers made their dramatic discovery in 1912.
Tommy and Jeff Morgan had only candles to light their way, a coracle to cross the lakes they encountered, rope to help with the dangerous climbs they undertook, but of course no map to help guide them! Today, you can enjoy this natural wonder without any of the difficulties they experienced over 100 years ago.
Be amazed by the famous “Rasher of Bacon”, the heavenly “Angel” and the “Alabaster Pillar” - just some of the beautiful formations discovered by the Morgan Brothers during their adventures.
These incredibly brave acts of discovery were not surpassed until 1963, when a relatively inexperienced caver, Eileen Davies, made a significant breakthrough in the exploration of Dan-yr-Ogof. The “Long Crawl” was finally conquered; so far this has led to the discovery of an incredible cave system with over 16km of explored passageways.
