In reply to Imedio:
The best one, Chapel Head Scar is bird banned until the end of June and is outside the mountains near the estuary. There are a few other crags along there but they're not great. A popular Lakes sport crag is Bram Crag Quarry - in the mountains and would be hikable from many good wildcamping spots. But is is just a quarry by the road, full of mediocre routes many of which are loose. Or there's St Bees on the west coast - interesting sandstone, but not near anywhere you'd wild camp. Great bouldering there, and a beautiful spot.
Is it really not possible to borrow gear and learn to do some trad? There are stacks of amazing routes in the mountains where you can wildcamp and climb. We don't bolt these routes in this country, we save the bolts for the shit quarries and overhanging limestone. Just doesn't go together with wildcamping, which you do in the mountains. Another option, requiring even less gear, is scrambling. In many ways the best option as you can cover loads of ground, get to some really spectacular places and don't have to drag all the gear around.
