In reply to marktrik:
There is actually the Keswick Climbing Wall as well:
https://www.activity-centre.com/keswick-climbing-wall/
It is not very large but it has a bouldering area and top rope areas. If your favourite climbing is gritstone / sandstone outcrops, the top rope areas are fine. If you are more accustomed to loftier things then you may find the routes to be a bit of a one-move wonder. Run by a friendly bunch.
It is about 15 minutes by car from Keswick, in the middle of nowhere. Its cold so take a coat.
