Liddesdale

Liddesdale, the valley of the Liddel Water, in the County of Roxburgh, southern Scotland, extends in a south-westerly direction from the vicinity of Peel Fell to the River Esk, a distance of 21 miles (34 km). The Waverley route of the North British Railway runs down the dale, and the Catrail, or Picts' Dyke, crosses its head.
