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.
