Located in an abandoned mine, 419 meters under the mountains of Snowdonia in Wales, the ‘Deep Sleep’ hotel is the world’s deepest hotel.
Comprised of four private twin-bed cabins and a grotto room with a double bed, a dining area, and toilet facilities, Deep Sleep is a hotel unlike any other. Set deep within a section of the abandoned Cwmorthin slate mine, 1,375 feet (419 meters) underground, it is being advertised as the deepest hotel in the world. If that sounds like the kind of place you’d actually want to spend the night, know that you’ll not only have to pay up to £550 ($688) per night, and traverse a ‘steep and challenging’ route through the old mine shafts to reach it.
