Abandoned slate mine in Wales becomes world’s deepest hotel

snowdonia, wales — The Welsh countryside offers stunning views from the rugged mountains that frame the vast landscape. But while you won’t see any of that from the Deep Sleep Hotel, it’s no less spectacular, and getting there is half the adventure.

A helmet, headlamp, boots and climbing guide will be provided upon check-in.

The journey 400 feet underground to the world’s deepest hotel in Snowdonia, North Wales, is nerve-wracking.

Guests descend into dark caverns, travel through flooded tunnels, zipline across vast abysses, and navigate through fairly narrow passages.

For more than 200 years, miners have been extracting slate from Mount Snowdon, much of the work done by candlelight. In the process, they created a maze of tunnels.

“We go miles there and miles there,” explains guide Janine Catherine. “Yes, it’s a big place.”

Deep Sleep Hotel, which first opened in April 2023, is approximately 4 hours away. Once you arrive at the hotel, you’ll find a climate-controlled cabin and the groundwater helps generate electricity.

Wi-Fi and restrooms are available. There is spring water, but no showers.

Dinner is in the pouch.

“You can’t miss this,” said guest Mark Green.

Guest Sam Frith added it was a “once in a lifetime opportunity”.

A good night’s sleep for two in a cabin costs nearly $500 per night.
