Cave
Access The lower entrance is on Dan-yr-Ogof property and visiting parties need to contact the DYOCAC for access details. See the Access p.of the Cambrian Caving Council Website for current Access arrangements at http://www.cambriancavingcouncil.org.uk/cave_access.html
Description From the lower entrance, a narrow passage gives access to a large chamber 'Davy Price's Hall' which is now a showcave. From here, via an airlock through the radon fan housing, the cave develops into a series of rifts and chambers up which it is possible to climb to reach the bottom of the shaft to the upper entrance (Tunnel Top).
