Picnic area
Walking trail


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:

Foel Friog woodland, Dyfi Forest

Foel Friog is off the beaten track, near the village of Aberllefenni. It is easy to find from the A487 between Machynlleth and Dolgellau.

There is a pretty riverside picnic site and one waymarked walking trail past ruined farmsteads to the top of Pen y Bryn hill and back through oak woodland.

Walking trail

The walking trail is waymarked and starts from Foel Friog car park.  

Our leaflet gives you more information about walking in Dyfi Forest.

Pen y Bryn Trail

2 miles, 3.2 kilometres, strenuous

The Pen y Bryn Trail ascends a steep path through the trees before joining the forest track. It passes by derelict farmsteads and quarry remains, and offers superb views. It then descends through an ancient oak woodland and returns to the car park on a bridleway along the river valley.
