In North Wales there are many amazing old quarries and mine-workings.  Cwm Ystradllyn is just one – very remote with workings right at the end of the Cwm and also the remains of a village and barracks.

Track up to Cwm Ystradllyn Slate Quarry

The quarry at the end of the Cwm is huge and has a creepy atmosphere.

Such a special place to visit though – above Tremadog near Porthmadog.
