The area around Llanfachreth is a mix of green fields, forest and rough grassland, criss-crossed with footpaths and tracks. This provides a lovely setting for today’s interesting and varied walk. We set off towards Llyn Cynwch and along the start of the popular Precipice Walk, but soon leave this to descend through partially felled forestry and walk through the fascinating remains of the disused Glasdir copper mine, which was worked from around 1852 until 1913. This is followed by a wander through the nearby Arboretum, home to trees from around the world. Our route continues up to Fridd-goch-uchaf and thence to Ceunant Hŷll (Ugly Gorge), with views soon opening up towards the Rhinogydd. We then make our way round to Bwlch Goriwared, returning to the start via Cors y Garnedd and the base of Foel Offrwm.
