An unusual hotel is built on top of a natural spring at Huilo Huilo Biological Reserve, Chile. The steep-sided Magic Mountain Hotel is covered in trees and shrubbs, and has a waterfall toppling over the side to help it blend into its surroundings in a 250,000 acre nature reserve. It has a conical shape, which makes it look like a mountain, from which it gets its name. Water pours from the top of the hotel and down the side of the building 24 hours a day. [Photo/CFP]
