The nature path Ru de Lies starts at the end of the bridge (crossroad to La Magdeleine) in the village of Champagne.
It is a flat walk, along the path you will find panels with information about history, geography, geomorphology, flora and fauna of Antey-Saint-André, and also information about climatology, environmental laws and typical products of the region. Typical mountain plain woodland which thins out at intervals along the path, leaving space for clearings cultivated with permanent meadow. Species in the hardwood coppice are Ash, Alder, Maple, Lime, Birch, goat Willow, with occasional Larch and Scottish pine.
Along the path you will find benches, and after crossing an asphalt road a small pic nic area with tables and 2 barbecues. If you will go further on you will reach the quiet village of Lies.
