Discover Marnans: Saint-Pierre Church and Trails

Marnans can be explored from two very different perspectives: through Saint-Pierre Church and through trails that start in the village or pass through it. The church is the most important surviving part of a medieval priory of Augustinian Canons. The cycling route, pilgrimage trail, and circular hike each have a different focus and provide different details about their course, length, and duration. This lets you decide before your trip whether you are more interested in cultural heritage or a particular way of exploring the area.

Saint-Pierre: Church and Priory

Saint-Pierre de Marnans Church dates from the late 12th century and has been listed as a historic monument since 1846. It is the most important surviving part of a medieval priory of Augustinian Canons. The construction date and the historic-monument listing provide two different points of reference for the building’s history. Saint-Pierre is therefore a tangible point of interest for travelers interested in religious architecture and medieval history.

The church is open year-round on request and can be visited independently free of charge. Take the need to request access into account when planning your visit.

Marnans and the Chambaran natural area

Marnans is part of the ZNIEFF “CHAMBARANS,” a type 2 ecological inventory area. The Chambaran area, which includes Marnans, is characterized by geology comprising quartzite clay, which has no equivalent in the French Alpine regions. In the wider Chambaran natural area, which includes Marnans, wet meadows and heathlands provide habitats for many species with Atlantic affinities and some mountain species at an unusually low elevation. The inventory classification applies to the ZNIEFF; the geology and habitats describe the wider Chambaran natural area. When considering the destination, you can therefore keep in mind both a specific place to visit and landscape features of the wider area.

Cycling route, pilgrimage trail, and circular hike

For cyclists, “Les Chambaran à vélo” passes through Marnans. Signs point to cycle-tourism route No. 2. This signage gives you a specific reference point if you are interested in the cycling route.

The 51.8-kilometer “Sentier de Compostelle par les Chambarans” pilgrimage trail runs from Gillonnay to Montmiral via Arles and passes through Marnans. It is accessible year-round. Its length, endpoints, and route via Arles give it a different character from a circular trail that starts in Marnans.

The “Circuit par Mermes, sa combe et son étang” circular trail starts in Marnans. The 11.9-kilometer walk is listed as taking 3 hours and 30 minutes, with 269 meters of ascent, 269 meters of descent, and a maximum elevation of 617 meters. These figures give a clear idea of both the time required and the elevation profile for this specific circular route, providing a concrete basis for planning your hike.

Another route, “En forêt de Chambaran,” also starts in Marnans. The available planning details therefore differ: the pilgrimage trail lists its total distance and route, while the circular hike also gives a walking time and elevation figures.
