Llan Ffest to Penmachno Slate Trail

Cwm Penmachno (historically called Tre-Gynwal) is a village at the head of Cwm Machno in North Wales.

The Blaen y Cwm Quarry was a slate quarry located east of Blaenau Ffestiniog in Wales. It was first worked in some time between 1813 and 1818 and sporadically after that until 1914. The quarry was connected to the Ffestiniog Railway at Duffws Station via the Rhiwbach Tramway.

Rhiwbach Quarry was a slate quarry located to the east of Blaenau Ffestiniog in Wales, at the far end of the Rhiwbach Tramway, which connected it to the Ffestiniog Railway. Commercial operation began around 1812, and it finally closed in 1952. It was the last Welsh slate quarry where workers lived in barracks on the site.
