Wet Sink (Slaughter Stream Cave)

Grid reference: SO 5820 1375

At 11km long, Wetsink has a lot to offer in caving trips. There is a bit of everything in here, pitches, streamways, sumps, fossil passages, formations and dig sites. It also has the added interest of containing a large number of prehistoric animal bones as well as the more recent "Norman" the dog, whose lonely skeleton lies a fair way into the cave, his wandering footprints seen left in the mud floor.

There is sometimes confusion over the name of the cave. The cave system is called Slaughter Stream Cave and Wet Sink is an entrance into the system. (currently the only one that is open).

The cave was featured in a programme made for Channel 4's Extreme Archaeology series.

Wetsink is situated on private land, and is gated.
Access is quite easy, just contact Andy Clark to collect a key.

There have been several incidents of sewerage pollution in the cave. The cause of which has recently been the failure of pumps at the local pumping station, which is the responsibility of Welsh Water. The pumps have now been replaced, which will hopefully solve the problems.
We would request all visitors to Wetsink to check the sewerage overflow pipe which feeds into the adjacent Drysink. If this IS flowing, please ring the Environment Agency Wales hotline 0800 807060, and if possible take any photos (above and below ground) to enable the event to be followed up.

There is a gallery of photos.
