From Cambridge University Caving Club - CUCC wiki
We hold regular training sessions in Cambridge to practice the technical ropework manoeuvres above ground. These are free of charge and all equipment is provided.
Our regular venue is the Fitzpatrick Hall stage in Queens' College; see here for a map.
(It might be advisable to wear some old scruffy clothes, as the club's harnesses and the like tend to pick up more mud underground than it is possible to clean off.)
