Saint-Barthélemy-de-Séchilienne: Hiking and Heritage

Saint-Barthélemy-de-Séchilienne can be explored through two themes: hiking and the area’s religious heritage. The wetlands along the Romanche and a documented connection to ecological restoration are also part of the picture. When planning your stay, you can distinguish between hiking routes by length, duration and difficulty, while also taking historical traditions and a dated cultural event into account.

Hiking: routes with different profiles

The circular route around Lac Mort is about 8.5 kilometres long and takes five to six hours. Signposts and yellow markings indicate the route. It can be reached from Saint-Barthélemy-de-Séchilienne via the D113; parking is available in the village. The route length and stated duration give you concrete points of reference for planning your day. Check road, parking and route conditions before setting off.

The difficult hike to Le Grand Serre via Grande Cuche has a different profile. This 12.33-kilometre circular route starts and ends in the hamlet of Le Sapey. The highest point is at 2,135 metres; the route includes steep sections and several unmarked stretches. Difficulty, elevation and trail markings are important differences to consider when choosing this hike over the Lac Mort loop. Check current trail conditions before setting off.

The hamlet of Le Sappey is also listed as a starting point for hikes within the PDIPR. Here, the names Le Sapey and Le Sappey refer to the respective details given for the hiking options mentioned. Local facilities and trail conditions may change; take this into account when planning. The two specifically described loops also differ in length and difficulty rating: the duration and markings are specified for the Lac Mort loop, while the Le Grand Serre hike is explicitly described as difficult.

Chapelle Saint-François-Régis and historical traditions

The Chapelle Saint-François-Régis dates from the 18th century and is located above the village. A hiking trail passes directly by the chapel. The road from Saint-Barthélemy-de-Séchilienne to Laffrey also provides access. When planning your route, you can take both the chapel’s location and its connection to the trail into account without treating the two described access routes as one and the same.

A summer tradition passed down through generations is associated with the chapel: until recently, some salt blessed by the priest was mixed each year with the animals’ salt to protect them from an epidemic. The time frame is part of this story. It describes a tradition from the recent past, not a confirmed current practice.

An archival record from 1734 documents an indulgence for the faithful who visited the church of Saint-Barthélémy-de-Séchilienne on this saint’s feast day. This historical account complements the more recent tradition associated with the chapel. The record concerns visits at that time and says nothing about access today.

Natural areas along the Romanche and culture

Île Falcon, in the municipality of Saint-Barthélemy-de-Séchilienne in the Romanche Valley, is a site for ecological restoration measures. The municipality’s natural areas also include two wetlands along the Romanche. Several species and habitats requiring protection have been identified at the Île Falcon and Pont de Gavet sites. The management plan covers both sites, Île Falcon and Pont de Gavet.

Performing arts have also been part of local cultural life: the fourth edition of the La Passerelle festival took place in 2026 at Espace culturel La Clouterie in Saint-Barthélemy-de-Séchilienne. If an event is important to your travel dates, check the dates for your chosen period. Together with the chapel, the salt tradition passed down through generations and the hiking routes, this offers a stay in which you can plan nature and culture separately and give each the weight that suits your interests.
