Gravel paths in all directions, views of Mont Blanc, the Alps, the Monts du Lyonnais, Pilat and Lyon What is it? Located south of the Lyon metropolitan area, the ENS des Grandes Terres covers more than 400 hectares crossed by 17 km of marked hiking trails and mainly occupied by farmland. A countryside setting surrounded by urban areas at the gates of Lyon! Each season is lived to the rhythm of the harvests and colors dominated by the fields of wheat, soybeans, barley and corn. However, it is the multi-colored roses that attract all eyes with their prestigious culture perpetuated by the historic rose growers. In the past, the vine was also part of the landscape shared today between walkers, joggers, farmers, cyclists, hunters and even riders from the Fort de Feyzin Equestrian Center. Not forgetting the local fauna with more than 40 different species of birds.
