Swimming and kayaking/ canoeing are not CSC activities. However, kayaking/ canoeing is done at Chipstead Lake through Bromley Canoe Club, which is a Group member of CSC. You can contact Bromley Canoe Club at: https://www.bromleycanoeclub.org.uk/
Open water swimming on the lake is run separately by Triswim by arrangement with CSC. You can contact Triswim at: http://www.triswim.org.uk/ . Please note that Chipstead Lake is private property so you cannot use the lake or club property unless you are a member of CSC or an authorised organisation.
