Those Northumbrian crags look superb, do they tend to be quiet?
Peel Crag and Crag Lough are pretty quiet with climbers, we had a day at each a few summers back and only saw one other climber. They are absolutely rammed with tourists though as Hadrian’s wall runs across the top. They really are absolutely first rate in the easier grades. Good campsite at Winsheilds too.
The other Northumberland crags are a bit mixed. Kyloe can be popular but I’ve never seen it unpleasantly so. Bowden gets busy but mainly with boulderers.
