This wooden cabin is part of a nature trail in the Chalmessin nature reserve, a protected area that is home to a remarkable tufa marsh and limestone lawn. The cabin has a unique shape, as it is built with inverted oak tree tops that form a natural frame. Next to the hut, there is a reconstruction of a pile of charcoal and some panels that explain the history and work of the charcoal burners. The cabin is located in a wooded valley, where you can enjoy the sounds of nature and observe various plants and animals, such as orchids, sedges, butterflies, dragonflies and lizards. If you want to visit this place, you must follow the directions for the Chalmessin Reserve Discovery Trail.
