Jaillans offers several clear starting points for a visit of discovery: the Viaduc du Tram 1900, Sainte-Marie Church and a landscape defined by the Coteaux de Baret and the Monts du matin. There are also two trails with different features and an annual festival held in September. You can explore Jaillans according to your interests: as a place with a history of engineering and religion, as a landscape destination or as a reason to visit in September.

Landscape between the plain and the Vercors

Jaillans lies in the Coteaux de Baret, which mark the edge of the Valence plain. Near Jaillans, the Monts du matin are described as the first foothills of the Vercors. This means two different geographical reference points are part of the description of the area: the Coteaux at the edge of the plain and the Monts du matin in relation to the Vercors. If you are exploring the landscape, these names help define that setting precisely. The Coteaux de Baret place Jaillans at the edge of the Valence plain; its connection to the Vercors is established through the Monts du matin.

The Viaduc du Tram 1900

The Viaduc du Tram 1900 carried the tramway across the Serne. At 47 metres long and 17 metres high, it has two specific measurements, as well as a curved shape. Its length and height describe different dimensions, while the curve adds to the structure’s form. For travellers interested in the history of engineering, its function and construction can be considered side by side: the tramway crossed the Serne on the viaduct, and its form can be described by its length, height and curved course.

Sainte-Marie Church and its history

Sainte-Marie Church is in the heart of the village of Jaillans and is listed as a historic monument. Its earlier history includes an institutional connection to the Benedictine priory and Montmajour Abbey: it was once a Benedictine priory and belonged to the abbey. The north side also features the subject of Daniel in the lions’ den, accompanied by an inscription about the Old Testament event. Sainte-Marie thus brings together its former ecclesiastical affiliation and a specific religious subject. If you are interested in historical heritage, you can understand the church through both aspects: its history and the subject depicted, together with the inscription.

Two trails with different features

Les crêtes de Baret is a waymarked circular hiking trail that starts and ends in Jaillans. The Randonnée du Tram is an open trail maintained by volunteers that runs along the Serne and the Canal de la Bourne. A description dated 21 April 2026 highlights natural and historical points of interest along the route. The trails therefore have distinct profiles: Les crêtes de Baret is defined by its waymarking, circular route and Jaillans as its starting and finishing point; the Randonnée du Tram is characterised by its route along the waterways and its natural and historical features. This comparison can help you choose a trail based on the feature that interests you most.

A September event

The Médiévales de Jaillans take place in September and are among the village’s annual activities. If you would like to plan your visit around this event, check the specific dates for the year you wish to attend before travelling. September is therefore a clear seasonal reference point for planning a trip; Jaillans can also be chosen as a destination for its landscape and historical heritage.
