Tan y Coed is an easy to find woodland with a picnic site, walking trails and running trails, located immediately off the A487.

The Forestry Commission began planting Tan y Coed woodland after the First World War as the war effort had used up Britain's timber.

Planting continued through the Second World War with Land Army Girls, known as “Timber Jills”, carrying out the work. 

Today Tan y Coed is home to a pleasant picnic site with tables amongst huge trees in the large grassy area around the car park.

It is the start for two tranquil woodland walks past old moss-covered trees and along the river.

There is also an animal puzzle trail for families and two running trails.

Dyfi Forest

Tan y Coed is part of 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 walking trails at two other woodlands managed by Natural Resources Wales within Dyfi Forest. Go to Nant Gwernol and Foel Friog for more information.

Running trails

The Tan y Coed trails are a perfect escape for runners who are tired of running on the road or in the gym.

They offer a unique running experience with long climbs and steep descents along forest roads and muddy unmade paths over roots, rocks and streams.

The trails can be very muddy and trail shoes are recommended. It is suggested you take adequate bodycover, water, map, phone and whistle.
