Underground Sleepovers

5 star accommodation!5 star accommodation! [+]

Yes, you really can sleep underground in the abandoned slate mine workings on one of our awesome Underground Sleepovers!


If you’re a group of 6 friends, colleagues or family members we can tailor make a night underground just for you. Your overnight adventure can be as extreme or as sedate as you choose – maybe kick off with a fish and chip supper followed by hours of underground exploring with climbing, scrambling and balancing or a more sedate adventure with loads of mining history and stories from bygone times followed by a candlelit game of cards with midnight snacks.

Our expert guide will build a bespoke underground sleepover especially for you. Please call us to find out more and to start planning an overnight adventure you’ll never forget.
