Dan yr Ogof, one of the finest and well preserved caves in South Wales. Found at the head of the Swansea Valley, the cave spreads some 17Km into the Black Mountain. The journey through Dan-yr-Ogof is an experience you will never forget. The river Llynfell emerging from a cave at the base of the cliffs at Dan-yr-Ogof farm has always been known. In 1912 Tommy and Jeff Morgan had the courage to explore the cave. They used only candles to light their way and arrows in the sand to find their way back. They discovered a wonderland of stalactites and stalagmites, but they were prevented from penetrating far into the mountain by a lake. Undeterred they returned, this time with coracles. A coracle is a traditional one man fishing boat found on the rivers of West Wales. They crossed not one lake but four. They discovered more magnificent passages and chambers, but again the way on was denied them. This time it was a tight crawl. This crawl was not passed until 1963 when Eileen Davies, a local girl and member of the South Wales Caving Club struggled through it. She and others have now found over 10 miles of unique cave. Cavers believe that this is the tip of the iceberg and that there is still much to discover. The journey through Dan-yr-Ogof is an experience you will never forget.....
