Come caving with CSS

Most of our current members live across the South of England and South Wales where we have a cottage adjacent to the Mynydd Llangattock limestone massif. This has some of the longest and largest caves in the country with 65+ kms of explored passages.

Are you new to caving?

CSS welcomes new members, offering them

the opportunity to make new friends and to

learn new skills, exploring the underground

world one cave at a time.
