Dyfi Forest - Coed Nant Gwernol, near Machynlleth

What's here

The Cascades Trail and the Quarryman’s Trail are closed due to a landslide.


Coed Nant Gwernol woodland lies on the edge of Abergynolwyn village.

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

The waymarked trails follow the riverside and explore the remains of Bryn Eglwys Slate Quarry. 

Please note that all the trails start from Nant Gwernol station but you can either park in Abergynolwyn village or at Abergynolwyn station.

Walking trails 

All of the walking trails are waymarked and start from Nant Gwernol station.

Leaflets are available from the Tal y Lyn railway stations and the Abergynolwyn community centre/café.

Please take care not to stray from the paths as the old works are dangerous.

Stations Link

1 mile, 1.6 kilometres (one way), moderate

The Stations Link is a linear route between Nant Gwernol station and Abergynolwyn station - there is a steep climb if you start from Nant Gwernol and a steep descent from Abergynolwyn. The trail offers views of the surrounding mountains and the Allt Wyllt incline, part of the former quarry. Please be aware of trains when walking over the level crossing half way along this route.

Cascades Trail

1 mile, 1.7 kilometres, moderate

The Cascade Trail climbs uphill, closely following the tumbling river. It then crosses a wooden bridge onto the old tramway and descends steeply alongside part of the old Allt Wyllt incline back to Nant Gwernol station. 

Quarryman’s Trail

4 miles, 6.4 kilometres, strenuous

This is a fairly strenuous walk with long climbs and steep descents. Highlights include expansive views of Cader Idris, waterfalls and the ruined mine workings of Bryn Eglwys quarry. 

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.
