With a surface area of around 165 000 hectares, Upper Jura Regional Nature Park covers the three departments of Ain, Jura and Doubs. Its highest point is the Crêt de la Neige peak, at an altitude of 1 720 metres, in the department of Ain.
A series of wonderful landscapes full of mountains, rivers, waterfalls, mountain pastures, forests and villages lies in store for the delight of nature-lovers and hiking fans.
In the Jura, the Flumen gorges between Saint-Claude and Septmoncel; the Chapeau de Gendarme, a natural curiosity made of limestone layers shaped like an old policeman's hat; the wonderful Lamoura lake and the Les Rousses ski resort, are among the places to be discovered.
In the Doubs département, do not miss a walk in the Mouthe valley, covered with forests and prairies, which is notably where the Doubs River has its source. In Chapelle-des-Bois, the Michaud House heritage museum, housed in a 17th-century farm, recounts the life of the farmers over the last centuries.
Ain offers magnificent natural sites which are well worth a trip: the Faucille Pass, Mount Rond, Colomby de Gex, the site of Fort l'Écluse, the Crêt de la Neige and Crêt de Chalam peaks and the Valserine Valley are just some of the places you can discover on foot. At the Monts Jura winter and summer sports resort you can practise a number of outdoor activities, such as cross-country and Alpine skiing, hiking and mountain biking, golf and downhill luge.
Travelling through the Upper Jura Massive is also a chance to enjoy the local specialities, like famous Jura cheeses such as Comté, Bleu de Gex and Morbier, and visit one of the many fruit farms in this area.
