In reply to TN:
THE best place for Severes in Northumberland is Crag Lough, and, despite a couple of postings to the contrary here*, you should be OK on everything up to and including the brilliant Main Wall, which is 99% of the crag anyway. Peel Crag, which you pass on the walk in to Crag Lough, has 2 excellent severes also.
Camping at:
Winshields Camp Site
Winshields Farm
Tel. 01434 344243.
(Walking distance to the pub/crag)
* Information from NT Warden via BMC Access Rep. Do not go any further east than Main Wall and you should be ok. If the Peregrines get alarmed you'll know about it and just back off to the west a bit. They should be just about fledged by now.
