This 4 mile walk covers an area of significant industrial archaeology dating back to the 17th Century until the 1960s. Minerals such as coal, iron ore and limestone were mined in this confined area and there is much evidence of the infrastructure which supported it along this walk, bogie tracks, tramways, railway lines and a canal.. In addition, John Loudon MacAdam set up a tar works here and experimented with a variety of new road surfaces. At the far end of the walk we come across Tibbie's Brig, where in the early 19th Century Tibbie Pagan lived and eked out a living singing and selling her poetry.
