42,51 km cycling route from Nanchez to Pont du Navoy

Surely the most refreshing stage on this Jura cycling adventure! Once you’ve left the smaIl village resort of Prénovel (c.1,000m in altitude), you come to one of the Jura’s major sites, the Plateau des 4 Lacs (namely Ilay, Narlay, Grand and Le Petit Maclu). Nicknamed the Petite Écosse du Jura (or ‘‘the Jura’s Little Scotland’’), this area’s natural, traditional sides, and its patchwork of greens and blues, prove very appealing. Also admire the top of the Cascades du Hérisson, a series of waterfalls that are another must-see site, before taking a well-shaded road to the banks of the Lac de Chalain, the Jura’s largest natural lake, best viewed from the Belvédère de Fontenu (a viewing point that you can reach by bike).
