On the summits of Mount Lozère, the full nature resort of Mas de la Barque is a welcoming site and a crossroads of sporting activities. Located in the heart of the Cévennes National Park, this site also offers access to large open and forested spaces in which there is tranquility conducive to a gentle and respectful discovery. Promoting an emotional and playful approach, interpretation devices are offered to the public in order to discover the richness of natural and cultural heritage. A course in the natural environment around the resort offers families to take their first steps as naturalists between forest and wetlands. Nearby, a pontoon set up on the edge of a bog offers all the public, regardless of their disability, a multi-sensory discovery about this rich and complex environment. The rising public will be able to reach one of the peaks of the massif: Cassini peak. With a 360° orientation table, this place also reveals the history of the region’s first cartographers.
