Walk the Wales Coast Path from Aberdyfi to Machynlleth

The Wales Coastal Path from Aberdyfi (Aberdovey) to Machynlleth takes us far inland, parallel to the Dyfi Estuary as opposed to the coast. At the last two major estuaries of the Dwyryd and Mawddach, the walker had the luxury of using bridges as a shortcut, while here you’ll need to wear shoe leather in order to cover the 2km or so that divides Aberdyfi and Borth on the far side! There used to be a ferry from Aberdyfi to Ynyslas, which was stopped many years ago and the railway bridge here was built further inland at Dyfi Juncion. This is also the final section of the Wales Coast Path in Gwynedd and Snowdonia as you briefly enter Powys which boasts the shortest section of the coastal path.

Aberdyfi to Pennal

From Aberdyfi, the coastal path again heads for the hills. Following the Panorama Walk along a high ridge, it provides wide views across the Dyfi estuary and the hills of Snowdonia. The ancient route takes you high over Cwm Maethlon (Happy Valley), a popular location with tourists and walkers alike.  On the way, you’ll spot Carn March Arthur is a deep mark in the rock made by King Arthur’s horse, Llamrai while pulling the afanc from nearby Llyn Barfog. There’s a slate marker nearby. The afanc was a legendary creature said to have brought havoc onto nearby Aberdyfi. Afanc is also the welsh word for beaver – which would have been a common animal in the area around that time, but more likely to be an embellishment than a mutated killer beaver on the loose in the welsh hills. Llyn Barfog is a short diversion from the Wales Coast Path from here, and barring any beaver phobias, perfectly safe these days.

Pennal to Machynlleth

From Pennal, the path again strays into the hills. Unfortunately, this time the view is mostly obscured by the plantations and the forestry tracks hardly inspiring. They do at least make progress reasonably easy going. On the descent, you’ll pass close to Bron-yr-aur where Led Zeppelin spent time in 1970 to write some of their best known tracks, including Immigrant Song and Stairway to Heaven to name a few. Please note that this is a private residence.
