Visiting the Glandieu waterfall is now a different experience. On Saturday 12 September 2026, the Bugey-Sud community of communes, the local intercommunal authority, unveiled new facilities at this natural site between Brégnier-Cordon and Groslée-Saint-Benoit. According to the authority, it draws more than 50,000 visitors a year.
A footbridge to see the falls and protect the site
The main feature is a secure metal-grating footbridge with several viewpoints over the falls. It has two purposes: giving visitors a better view of the waterfall and keeping footfall on a set route so the surrounding habitats are not trampled.
The old marble works reopened
In the hamlet, the old marble works has been fully restored and opened up to the outside. The authority plans to use it for farmers’ markets, exhibitions, cultural events and local crafts. No dated programme has been published yet.
Environmental measures
The project comes with several measures:
- protecting the vegetation along the riverbanks;
- replacement roosts for bats;
- a five-year scientific monitoring programme.
The work cost €1.9 million excluding VAT, funded in particular by the French State, the Ain Department, the Compagnie nationale du Rhône (the Rhône’s hydropower company) and the European Union.
What it means for visitors
Paths around the waterfall are now clearer and safer. Please stay on the footbridge and the marked trails: that is exactly what they are there for.
Our waterfall guide covers access and site rules. Full details are in the announcement by the community of communes (in French), and you will find more outdoor ideas in our nature and walks section.
