From Cambridge University Caving Club - CUCC wiki
The gear page tells what is needed for a caving trip, including the caving gear which can be borrowed from the club.
The cost of a meet usually includes transport, accomodation and breakfast/ dinner in the hut. There is a tiny fee to borrow club gear.
To get ready for the most exciting trips, CUCC organises training in single rope technique (SRT).
Last but not least, safety deserves a section on its own.
