Sala Silvermine, Sweden

The Silver Mine Hotel can offer you the deepest room you're ever going to find on the planet. Dropping down to 155 meters under the ground, the hotel comes with a tour guide who is on call to bring down visitors, leave them with refreshments, and return the next day to guide them out of the cavity.

A staff member remains available above ground for the duration of the stay, contactable by an intercom radio. Guests are also reminded that cell phones do not work this deep underground! There is a toilet located 50 meters (165 ft) below ground, however guests will have to use the bathroom facilities in the adjoining hostel above ground. 

 

The mine also features two dining rooms in the vicinity of the hotel suite, where dinner guests can experience a banquet in a truly unique environment.

Here you will see dark winding galleries, vast caverns and magic lakes. Even to those not familiar with mining, the underground setting is sensational. It is cold, damp and dark, but very beautiful.

Experienced guides tell you of a fantastic chapter in industrial history. During its heyday, production amounted to more than 3 tons of silver a year, and a total of more than 400 tons of silver and about 40,000 tons of lead were extracted - completely by hand! Most of the silver was used in manufacturing coins, but artefacts were also made.

 

Above ground, in the southern area of the mine, lie several high wire adventure tracks, including ropeways, hanging bridges and other tree challenges. But if you'd prefer to go underground, adventurers have the opportunity to go cave diving. The cave dive offers a limited number of divers access to explore the mine's underwater environment. The water temperature is constantly a chilly 2 degrees Celsius / 35 degrees Fahrenheit, however divers braving the cold conditions are promised a "spectacular scenery" experience.

A night's stay in the underground suite at the Sala Silvermine will cost approximately US$580.
