A small stream sinks into this cave and flows down the side of a roomy, meandering passage with decorated chambers. After about 180m, a well shaft provides a serviceable exit but the stream flows on for a further 40m to Pool Chamber. Muddy water in a duck leads to a further small chamber where the stream sumps.
The stream from this cave surfaces again at Schoolhouse Rising, then passes under the road through Pointless Cave to sink again before finally rising at Springwell where its waters flow into the Cladagh River at Marble Arch.
