A month ago, I enjoyed my third day out on the hills to the east of Bridge of Orchy. This group of five Munros, and Beinn Dorain in particular, must be among the most eyeballed in the Highlands, with the busy A82 and West Highland railway line both skirting the western edge of the range, giving the passing traveller impressive closeups of stream-riven slopes climbing to 1000 metre-high summits, and furtive glimpses through lonely glens into the interior.
