This is a large circular that allows you to discover the different environments of the Bugiste region. Part of it is dedicated to the Lésines lake and the Marais de Vaux marsh, which can be crossed thanks to the facilities provided. The main part runs along the ridges above Cormaranche, with the climb to Golet Marmier and Planachat, the crossing from Col de la Clye to Col de la Rochette via Gigimont, then the climb to Haiea d'Amont and Cornillon. The descent passes through Notre-Dame de Mazières and Trou de la Marmite.

Departure from Hauteville-Lompnes (Ain)
This hike is based on the 4 belvederes walk. The route has been modified to take into account the opinions of hikers who have given their feedback. In particular, the trail is more precise and the parts considered less interesting have been removed. We are delighted with this new version, which is particularly suitable for hot days (tested during the heatwave of August 2025).The route is mostly through woods and on unpaved paths or tracks. It offers splendid panoramic views from various viewpoints as well as iconic sites: Trou de la Marmite, Notre-Dame de Mazières Chapel, etc. On a clear day, you will have the pleasure of admiring Mont Blanc.

This is the second stage of the five-day "GRP® de la Valserine" hiking trail. The hike allows you to quickly leave the city behind and gradually climb to the Plateau de Retord, where you will have a beautiful view of the path ahead and, if you are lucky, a panorama of the Alps. Then cross over to the other side of the Jura mountains via Giron 1000, the highest commune in the Ain department. The Monts Jura resort in the village of Lélex will welcome you and help you prepare to climb the highest peaks of the Jura! Finish in style with a visit to the Pertes de la Valserine.
Part of the route crosses the Haute Chaîne du Jura National Nature Reserve, which is subject to specific regulations:Dogs are not allowed, even on a leash, and camping in tents is also prohibited.Please respect these rules to preserve the richness of this exceptional environment.
