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 with some of the longest and largest caves in the country with over 65 km of explored passages.

Explore the amazing

world beneath your feet

The club caters to all levels of caver and

welcomes new members with both broad

and specialist caving interests including

photography, cave surveying, geology,

science, and the discovery of new caves. 

Beginners can acquire practical skills and

know-how, gaining knowledge about caves

and caving in the company of experienced

members while exploring the natural beauty

of the hidden underground world.
