You can stay as high as 72 feet off the ground in one of these bungalows which can be accessible by a staircase, a bridge or even motorboat. La Cabane en L’Air, which literally means “the Cabin in the Air,” is actually a collection of about 200 tree houses built all over France. One of them, in Orne, has a terrace for sunbathing. Mountain-biking lovers will find extra thrilling activities. If you have always wanted to get on a hot air balloon, you will get a chance to fulfill this dream as well.
