yeah I think if I was to go to up ont common I'd park at Housteads, not been before though so I bet you'd have to pay... Or somewhere nearby then ;)

Yeah Routin Linn definitely wheelchair accessible! So is the main one at Lordenshaws, if you feel fit enough to push her uphill on grass... not too bad I wouldn't have thought, on a dry day when the ground's hard. I've seen buggies up there.

another one would be Castlerigg but the ground's a bit softer...
