This is a river cave with generally easy walking passages following the river. The entrance follows a narrow and low passage accessed at a stream sink and is very wet. This section is prone to severe flooding. Side passages are generally small with a few larger sections. One fairly lengthy section of the main route requires the caver to paddle in less than a metre of water with less than half a metre of airspace. This section has a dry bypass. About a third of the passage length is accessible only through divers' sumps. Access is controlled only by the local farmer who seems not to dislike cavers, charging only a small goodwill fee. A survey is available on the UBSS site.
