Sink Doline
Access From the dry river bridge at Bridge Cave, follow the track to Pant Mawr House ruins, until it leaves Sarn Helen Road, then carry on due North following the Western of a pair of parallel lined walls for about 365 metres to a point where it turns NE to meet another wall. Then go NW for about 50 metres.
Description The swallet is a vertical collapse in the limestone with a small stream entering from the West face. The North approach is a steep boulder slope going down into the rift, water worn, where a stream can be heard down below. It is situated in a shallow dry valley or collapse region leading down from the sink of the same name. A very promising dig.
