Welcome to CSS

We are one of the foremost caving clubs in the UK, formed in 1956 by London cavers but now with members from all regions. We welcome new members of any ability from all areas. The club owns a cottage in the Brecon Beacons National Park in South East Wales which is a focus for many of our underground activities, projects and social activities. We also run caving weekends in other parts of the country, and occasionally abroad too.

The club owns an extensive library of caving books and periodicals available to members. We produce a monthly newsletter with details of forthcoming events and write-ups of recent caving activities and other news. We also publish occasional exploration journals and have large scale surveys of many local caves for sale: the results of our members' discoveries and work over many years in the 150km or so of natural limestone passages within a few minutes drive, or sometimes just a short walk, from our front door.
