Well there's the FRCC all over the Lakes as well as clubs in each of the bigger towns (Kendal, Penrith, Carlisle, Cockermouth, Barrow, etc).
Depends on what you're after.
Further more, there's lot's of 'outsider' clubs that have a worth while presence in the Lakes, such as Lancashire C&CC, Fylde, etc.
The trick isn't finding a club, but finding one that suits your needs.
