to the cave has been controlled by the Mynydd Llangatwg Cave Management and Advisory Committee; this means a key must be obtained to gain access through the gate, and the log book should be signed. Round trips to the "Hall of the Mountain King" take about two and a half hours while those to the "Promised Land" take six hours. There is a fixed ladder at the first boulder choke and climbing aids at the second boulder choke, but otherwise cavers need to provide their own tackle. The cave sometimes floods, with a sump forming beyond the first boulder choke. References Craig a Ffynnon Craig a Ffynnon Caves of Powys
