Henllys Vale
Trail visiting various pieces of industrial archaeology.
OS grid ref SN 755125
The valley of the Afon Twrch was home to industry in times past. Follow the old tramway to see an impressive chimney which is virtually all that remains of Henllys Colliery. Nearby are substantial limekilns. The strikingly straight course of a former tramway can be followed across the moors above these ruins to disused quarries.
