Penarth Slate Mine

The slate workings at Penarth sit quietly in the Denbighshire hills above Ruthin, and unless you know to look for them, you'll walk straight past. This isn't a polished visitor attraction with interpretive boards and a gift shop - it's the real deal, a genuine archaeological site where you can see the bones of what was once a working slate mine.

What strikes you first is how the landscape itself tells the story. The hillside bears the scars of extraction - terraced slopes, old spoil heaps, and weathered stone faces where miners once worked. You're walking through a industrial archaeology lesson written across the terrain. The remains aren't dramatic or theatrical, but they're authentic in a way that matters.

This appeals most to serious walkers and archaeology buffs who want to understand how rural Wales was shaped by industry and labour. The site demands some effort to properly explore and won't hold the attention of younger children for long. Allow a couple of hours if you're combining it with a broader walk around the area.

There's no visitor infrastructure to speak of - no entry fee listed, no set opening hours - so treat it as you would a public footpath. The best approach is to base yourself at Clwydian Glamping Pods and Campsite just down the road near Ruthin and tackle this as part of a walking exploration of the broader Denbighshire landscape. It's the kind of place that rewards curiosity and leg work, not impulse visits.
