This might well be a bit of a cop-out for me. I have been to Kendal and Windermere before (when we were kids, camping up here) but Westmorland is really small and I couldn't think of anything else to do on a cold, wet May Monday. What I don't remember doing is the Windermere boat ferry which takes cars across the lake. I suppose I should mention that Lake Windermere is in the Lake District National Park amid absolutely stunning scenery, even on a cold, wet May Monday. I told the GPS to avoid main roads so I ended up going down some really tiny tracks to get around, great fun just driving around, enjoying the views and the cracking roads. Kendal (home of the famous Mint Cake) is really just a sleepy country town at this time of year but I would guess that come the summer months it gets extremely busy with all of the tourists heading in. Even today there were quite a lot of the hardier types of walkers around.
