World’s Deepest Hotel: Located 419 meters beneath the mountains of Snowdonia in Wales, the “Deep Sleep” hotel is situated in an abandoned mine and is recognized as the world’s deepest hotel. This unique hotel is composed of four private twin-bed cabins and a grotto room with a double bed, dining area, and toilet facilities. It is set deep within a section of the abandoned Cwmorthin slate mine, 419 meters underground, and is being advertised as the deepest hotel globally.
However, to reach the hotel, visitors must pay up to £550 ($688) per night and traverse a “steep and challenging” route through the old mine shafts. The hotel was inaugurated in April by outdoor activity company Go Below and is only open for business one night per week, on Saturdays.
Patrons begin by making reservations online and then travel to the Go Below base near the town of Blaenau Ffestiniog on Saturday evening, where trained guides await to accompany them to the underground hotel.
After trekking for 45 minutes through the mountains, visitors gear up at a small cottage and prepare for their descent into the abandoned Cwmorthin mine, the world’s largest abandoned slate mine.
The challenging route consists of old stairways, derelict bridges, and slacklines, and reaching the hotel takes about an hour.
Once at the Deep Sleep Hotel, guests are treated to a warm drink and an expedition-style meal before retiring for a “deep sleep.”
The temperature in the world’s deepest hotel remains a constant 10 degrees Celsius all year round, but the thickly insulated cabins are reportedly quite cozy. They also feature running water, electricity, and even Wi-Fi through a one-kilometer-long ethernet cable from a 4G antenna on the surface.
The Deep Sleep Hotel took the title of “world’s deepest hotel” from a suite in Sweden’s Sala Silver Mine, which was 154 meters underground
