"If you're looking to explore the natural scenery of Bordeaux, there are a series of eight shelters located along the region's outskirts where travelers can stay free of charge, with a one-night maximum, as part of the Les Refuges Périurbains project. The shelters don't have water, electricity, or heat, but they're close to attractions like flowing rivers, ancient castles, and stargazing spots and come in designs that range from an adorable owl to a giant snail sitting on the water. Reservations can be made online, with the shelters open from March through October each year." - Travel + Leisure Editors
