Description
Cave #1
This is the “main” cave you ca see from the roadside and has a huge entrance of around 30 feet in height. There is an immediate left/right fork with the left fork being short and the right fork running into the hillside.

The left fork has a high Aven which appears to be free climbable with skill but has the benefit of some old bolts in situ to assist. It is not know where this leads.

The right fork goes to a tight squeeze at the back heading downwards (after climbing onto a uddy ledge) as well as a chamber to the left which had two avens – one very high and unreachable whilst the other is possibly free climbable again.

Cave #2
Located to the right of Cave #1 and around the side of the cliff face. This cave has a very high entrance (about 30 feet) and is large in size but quickly becomes silted with a crawl at the back in the silt (possibly an abandoned dig). There appears to be a high passage running off near the entrance when you look back on yourself but it could not be reached to explore.

Cave #3
Located just to the right of Cave #2, a similar entrance leads to a silty climb which takes you to two belly crawl passages – one leading into the hillside (unexplored) and the other takes you to cave #4

Cave #4
This is really just a grotto which looks out over Llandulas and is reached either by a scramble up the rock face or by using the internal belly crawl in cave #3

Cave #5
This is to the left of Cave#1 and is located around a hundred feet away and slightly higher up the rock face. It is short (maybe 30 feet) and heavily saturated with calcium nitrate.
