Redesdale is a valley in western Northumberland, England. It is formed by the River Rede, which rises in the Cheviots and flows down to join the North Tyne at Redesmouth. Redesdale is traversed by the A68 trunk road, which enters Scotland via Carter Bar at the head of the valley. Redesdale contains the settlements of Elsdon, Otterburn, Rochester, and Byrness. Otterburn is the site of a British Army installation, Otterburn Training Area. A portion of Redesdale to the west and north of Otterburn forms part of Northumberland National Park and includes the Redesdale Forest, the northernmost part of Kielder Forest. From Wikipedia
