If you want to avoid crowds in lakes go to the western fells, harder to get to so less day trippers had some great times in Buttermere, 2 good pubs campsite, peace, fells and lake - bliss.
Hawes in dales is lovely too, and has the Wensleydale Creamery and Shop/museum. Hills, beer and cheese what more do you need!
On the same theme, the drive to Wasdale Head (pub at the end) is stunning. Love the lakes.
