Getting back to nature doesn't have to mean getting back to sub-par accommodations. The Treehotel offers five unique treehouses, each built with an eye on sustainability. They include a Mirror Cube, a UFO-shaped space, and bright red building strangely named The Blue Cone. Apart from the modern interior design, the hotel also offers a tree-based sauna and hottub, various outdoor activities, and easy access to the restaurant in the nearby town.
