James,
I realise that this is now a bit of a late response, but Windermere C&CC clubsite is one of our regulars ... but definitely only out of season as it's quite a big site and gets very busy.
It's actually about 7 miles from Windermere, so don't expect to wander into the town of an evening!
There's good walking locally, especially if you prefer the lower-level rambling, but it's also not far from some more strenuous walks.
Dog walking from the site is good, with a public footpath running from the site to Staveley (about 2 miles).
Talking of Staveley, they have 2 excellent pubs - The Eagle and Child, and The Beer Hall (which is inside Hawkshead Brewery).
There's also a small 'pub' on site which does good basic meals.
Let us know what you thought of the site.
John
