Llechwedd Slate Caverns, in Ffestiniog, Gwynedd, is a former slate quarry turned adventure site where most activities take place underground. You can bounce in a cave twice the size of St Paul's Cathedral, tackle a Via Ferrata up a slate cavern wall, play underground adventure golf, or join a Deep Mine Tour to learn about the quarry's history. Old quarrying buildings and slate veins remain visible on site. It's dog friendly, cashless, and has an on-site café and gift shop. The attraction is open all year except Christmas Day and Boxing Day, and arrival 30 minutes before your activity is required. With Blaenau Ffestiniog station just 0.7 miles away and 40 bookable places to stay within 5 miles, it's an easy base for an overnight visit.
