Tips from the Community
Cwmorthin Slate Quarry is an impressive area, a magical hanging industrial valley above Tan y Grisiau that highlights Wales' industrial heritage with its massive works and ruins. It was in operation between 1810 and 1939 and has five different underground levels which were serviced with extensive trackways and machinery. Many of the surface buildings, such as the slate mills, can still be seen. If you are a photographer, this is the place to come in the early summer light or the cold winter mist.

The long abandoned Barracks and Mill buildings of Rhosydd Quarry in the Moelwyn mountains of North Wales on a changeable day last September. A break in the heavy cloud allowed a burst of sunlight through that lit up the shiny slate rubble to make it look a bit like water. The dark buildings stood out against the lower slopes of Foel Ddu.

The spartan barracks at Rhosydd, a hard place to live and work, not far from the summit of a mountain.

Car park gets full up top so park sensibly park close to next car gives more space for others. Don’t park in front of gate as this is used by farmer Go Below and mountain/cave rescue. More parking available at bottom of hill.

Small train station in the mountains - slate was once mined here - now a tourist attraction.

Slate was mined here above and below ground from about 1830. The remote location proved difficult, and a series of financial troubles hampered the quarry. It shut during WW1 and reopened afterwards until finally closing in 1948. At it's peak, this was the second-largest underground slate mine in North Wales. Today you can explore the spoil and some of the old machinery.

No haute cuisine, but coffee and delicious cakes and rustic soups and other dishes. Very good after the strenuous hike.
