Miss the days of playing in a backyard treehouse? Consider Treehotel a grown-up retreat into childhood, with a modern-design twist. The Swedish resort ultimately plans to build 24 separate, completely unique tree rooms. For now, there are five; one, the Mirrorcube, blends into the landscape with a mirrored exterior, while another, the UFO, resembles a flying saucer that didn’t quite make it to the ground. Guests check in and eat meals at a nearby restaurant about a five-minute walk away from their treehouses. During the winter, the resort offers dog-sledding and ice fishing, while summer guests can mountain bike or kayak.
Up to 4450 Swedish kronor ($662 USD) for a two-person stay in the Mirrorcube, treehotel.se
