see page 35 for location map
A major cave system under Esclusham Mountain. The cave radiates out in three directions. West towards Gas Pot. North west to Park Farm Swallets and north to Minera and Ogof Llyn Ddu. There is the potential for a 10 mile long system. At present only 4 miles have been discovered. Sink to resurgence is 2.8 miles. In the 18th C lead miners discovered 2500 feet of stream passage. This was reentered by the NWCC in 1984 after a long dig.
Entry is via a 330 foot deep entrance shaft which is locked and located in the middle of a private grouse moor. This followed by 60 an 30 foot pitches which finally reached the main river passage at a depth of 400 feet. The cave is gated. Key from NWCC.
