The name suggests a mighty geographical feature, something akin to the 1000m peaks of Snowdonia perhaps, however, Halkyn Mountain is much more modest in size (at its highest point it reaches just over 290m). Despite the lack of altitude and scale, this wild upland common still has considerable charm and a fascinating industrial heritage focussed upon its mineral wealth. The rich veins of lead ore that streak the limestone have been mined since the roman era, with a particular surge of activity in the 17th century when many miners from the Derbyshire area moved to work here. The mining ceased in the 1970s, however the large Pant-y-pwll-dwr limestone quarry on the northwest side of the ‘mountain’ remains active.
The summit plateau is criss-crossed by a variety of paths and several route options are available. Circular routes can be taken from Rhes-y-Cae or Halkyn itself. It is also possible to connect your walk with an ascent of the nearby hill, Moel Ffagnallt. Moel y Gaer is worth exploring too – this Iron Age hill fort is situated only a kilometre or two to the south east.
There are various parking options in and around the local villages of Rhes-y-Cae or Halkyn.
Mostly good footpaths, although variable in places.
