Overview

Dyfi Forest

Dyfi Forest lies mainly to the north of the River Dyfi between the towns of Dolgellau to the north and Machynlleth to the south.

Rugged peaks loom above the forested hillsides that are dotted with atmospheric ruins and slate spoil heaps.

Steam trains chug along the hillsides, now carrying holidaymakers, but originally carrying slates from the quarries to the coast.

There are waymarked trails through these three woodlands within Dyfi Forest:

Nant Gwernol (see below)
Tan y Coed
Foel Friog

Nant Gwernol woodland, Dyfi Forest

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 (see how to get here for more information).

Closures and diversions

Please note:

Sometimes we need to close or divert trails for your safety whilst we undertake maintenance work or forest operations
Occasionally we may have to close a site in extreme weather, such as high winds or snow and ice due to the risk of injury to visitors or staff
Please always follow any instructions onsite and make sure you follow any temporary diversion signs in place

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

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.

Cascade Trail

1 mile, 1.6 kilometres

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

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.
