Collonges lies between the Rhône and the Jura; the municipality stretches from the riverbanks to the summit of the Jura. Historic buildings and crossings are as much a part of choosing a place to stay as the Rhône landscape. Pont Carnot offers both perspectives: it is an arch bridge and also a landmark for the Marais de l’Etournel. Other highlights include churches with distinctive architectural and artistic features, further castle ruins and activities for puzzle enthusiasts. If you are looking for a hotel in Collonges, you can start by deciding whether local history, nature watching or a pre-arranged distillery visit will shape your stay.
Pont Carnot and the history of the Rhône
Pont Carnot is an arch bridge about 100 metres long, with three spans between Collonges and Chevrier. It opened in 1873 and was named after its designer, Marie François Sadi Carnot. At the ends of the parapet are sheltered alcoves with viewpoints. Anyone interested in bridge construction will find both a specific structural design and a story behind its historic name here.
The ruins of Château d’Ecorans once stood opposite Pont Carnot. They once defended the Rhône crossing, which was made by ferry. The bridge and the ruins thus represent different aspects of crossing the river: on the one hand, the arch structure; on the other, the historic defensive role at the ferry. These two themes complement each other in the history of the area, while serving different purposes.
Churches and castle ruins
The church in Collonges incorporates the walls of a former fortified house. Its outer walls are more than 1.50 metres thick, and one arrow slit remains intact. These features draw attention to a different kind of structure from Pont Carnot: not a river crossing, but traces of a fortified house within a church.
Another historic stop is the ruins of Château de Livron above Ecorans on Mont-Livron. They were historically associated with the De Livron family. This family connection adds a link to local history, while the ruins at Ecorans represent the former defence of the ferry crossing.
The Church of Saint-Théodule is also a cultural point of interest: it houses the protected painting «Saint Athanase?». Together with the traces of fortification in the church in Collonges, it illustrates two different ways of engaging with cultural heritage—architectural details on the one hand, and a protected work of art on the other.
The Marais de l’Etournel on the Rhône
The Marais de l’Etournel lies on the Rhône, in the municipalities of Collonges and Pougny, by Pont Carnot. It is a designated ENS nature area. An accessible path is provided for observing migratory birds. This links the area’s riverside location with a specific nature-focused activity: the emphasis here is on birdwatching, not historic buildings.
The contrast can help you decide what to do on your trip: Pont Carnot, the churches and the castle ruins invite you to explore architecture and history. In the Marais, by contrast, the focus is on observing migratory birds. Both are part of the Collonges landscape, but appeal to different interests.
Puzzle activities and a distillery visit
Loisirs G’events offers escape games in Collonges, which you can play independently or with a supervisor. Murder parties are also available, with or without actors. The formats therefore differ in how they are hosted: a supervisor is optional for the escape game, while the murder party involves the participation of actors.
The LA GESSIENNE distillery welcomes visitors by appointment at 250 Rue de l’Etournelle in Collonges. Be sure to arrange your visit in advance. To plan your stay, it may help to compare your interests: would you like to explore buildings and local history, observe migratory birds or choose a puzzle activity? A distillery visit is another option, but requires an appointment.
