Quite a few places on booking.com - we decided yesterday to go there on Saturday and had choice of quite a good range.
In a few days, you can go pretty much everywhere in the Lakes and some of them you’ll visit more than once because of the routes linking through the same places. Some suggestions:
Buttermere and Borrowdale - don’t miss Surprise View (trust me…)
Windermere to Pooley Bridge via Troutbeck and Kirkstone Pass
Langdales, Fell Foot and Wrynose/Hardknott Passes then continue to Eskdale and turn left to Ulpha
Grizedale, Tarn Hows and Coniston - there’s a lovely cafe on the shore of Esthwaite Water
Scout Scar near Kendal is worth half an hour to walk up the escarpment and see the view on a clear day
Try to avoid the main A591 through the middle of the area as much as you can. The back roads are loads more fun eg through the back of Grasmere to Elterwater is a 1000% better way to get to the Langdales or Skelwith Bridge than fighting your way through Ambleside
When you set off home, head south to the A590 eg from Bowness to Winster and the Lyth Valley. Much better than following the herd towards Kendal.
