This traverse was first done independently by two parties, in the summer of 1939, with I Charleson and W Forde claiming precedence over W. H. Murray & R. G. Donaldon a few weeks later (see W. H.

The area enjoys a general right to roam under both the English Countryside and Rights of Way Act 2000 and the Scottish Land Reform (Scotland) Act 2003. The Southern Cheviots include the Otterburn Training
