The remains at Croesor consist of a quarry track up from the village, used for road vehicle transport to the mine. Along the valley floor the Croesor Tramway ran leading up multiple inclines to Croesor and Rhosydd quarries.

The hydro-power station which was built to power the quarry was restored in 1999 and it once again produces power.

Just outside the mine gate there are a couple of buildings, probably a barracks for the miners.

Now entering the mine yard, on the left you have the remains of the winding house at the top of the incline. Just ahead of you is the remains of the fan house which ventilated the mine, and next to this is the adit.

The largest remains on site are the mill. Mostly a ruin now there are still some tunnels underneath but most have been bricked up from it’s time as an explosives store.

At the bottom of the tip there is remains of an old incline and a spoil heap where a lower adit was started but never finished.

Open access. Please be careful inside as there are many call outs from people doing the through trip to Rhosydd. Many of these are because people can’t find their way out the Rhosydd side. Please be prepared before entering the mine.
