Dyfi Forest - Coed Nant Gwernol, near Machynlleth

Welcome

Coed Nant Gwernol is a woodland on the edge of Abergynolwyn village.

The woodland takes its name from a rocky river gorge with cascading waterfalls.

On the plateau above the river gorge lie the remains of Bryn-Eglwys Slate Quarry which is now part of the Slate Landscape of Northwest Wales World Heritage Site.

The waymarked walking trails follow the river and explore the remains of Bryn-Eglwys Slate Quarry.

You can discover what life was like for the quarry workers and their families by listening to our audio trail which has been designed for use along the Quarryman’s Trail.

The Talyllyn narrow-gauge railway runs through Coed Nant Gwernol and the walking trails can be started from two of the stations along the line.

Dyfi Forest

Coed Nant Gwernol is part of Dyfi Forest.

Situated between the towns of Machynlleth and Dolgellau Dyfi Forest lies in the shadow of Cadair Idris.

The woodlands cling to the steep hillsides of the Tarren and Dyfi mountain ranges cut through by the Dysynni, Dulas and Dyfi rivers heading west to the nearby sea.

The whole area was once filled with thriving slate mines, employing hundreds of people.

The finished slate was moved to the coast via a system of tramways and steam trains for export.

The remaining trains now carry holidaymakers through the countryside.
