Ever wanted to sleep in an abandoned mine?

Deep Sleep in North Wales lets you do exactly that—1,375 feet underground in an old slate mine beneath Snowdonia.

It’s part adventure, part overnight stay, and definitely not your average hotel.

You start with a hike into the mountains, gear up with helmets and headlamps, then descend into the mine using old stairways, bridges, and sometimes even a zip line or boat.

After about an hour underground, you reach a huge cavern with a few cozy cabins and a candle-lit grotto room built right into the rock.

Dinner’s simple and shared with the group, then it’s lights out in your cabin—comfy, quiet, and surprisingly warm considering it’s always around 50°F (10°C) down there.

After a cosy night's sleep, fill up on the breakfast buffet before heading back up to the surface.

It’s only offered on select weekends and sells out fast, but if you’re into wild, offbeat adventures, this one’s hard to beat.
