Dyfi Forest

Foel Friog 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.
