Glandieu waterfall: access, parking and rules

In the south of the area covered by our guide to nature and walks in Southern Bugey, the Glandieu waterfall is the busiest waterfall around: the Communauté de communes Bugey-Sud (the local grouping of communes) counts more than 50,000 visitors a year. It is formed by the River Gland and falls in the hamlet of Glandieu, on the boundary between the communes (municipalities) of Brégnier-Cordon and Groslée-Saint-Benoît.

The Bugey Sud Grand Colombier tourist office gives a drop of more than 60 metres. Wikipedia describes two successive falls adding up to around sixty metres. The site is a site classé (a legally protected landscape) and has been designated an Espace naturel sensible (ENS) by the Département de l’Ain, the county-level authority.

A site redeveloped in 2026

On Saturday 12 September 2026, the Communauté de communes Bugey-Sud officially opened new facilities:

• a secure footbridge with a metal grating deck and several viewpoints over the falls. It also serves to channel visitors and protect the habitats;
• the hamlet’s former marble works, renovated and opened up to the outside, intended to host producers’ markets, exhibitions and events;
• environmental measures: preserving the vegetation on the riverbanks, replacement roosts for bats and five years of scientific monitoring.

The announced cost is €1.9 million excluding VAT. The power of the falls was harnessed for a long time: Wikipedia mentions a former marble sawmill and two small hydroelectric plants that are still running.

A mention of building work to check

As of 9 November 2026, the tourist office listing (updated on 3 November) still referred to “limited access due to work until spring 2026”. This wording appears to predate the opening, but the tourist office does not say what the current state of the viewing area is. If in doubt, call the tourist office on +33 4 79 81 29 06 (04 79 81 29 06 from within France).

Access and parking

Access is free all year round. The waterfall is viewed from a dedicated area that the tourist office describes as easy to reach. The terrace of the Bistrot de la Cascade, in the hamlet, also looks out over the falls.

There are two car parks outside the hamlet. You cannot park right next to the waterfall. The tourist office does not give their exact location as of the date we checked. For its part, the Brégnier-Cordon commune website mentions a waterfall visible from a roadside car park.

Published addresses also differ: the tourist office places the site in Groslée-Saint-Benoît, while other sources say Brégnier-Cordon. The waterfall actually sits on the boundary between the two communes.

On foot or by bike

The site is a few minutes from the ViaRhôna, the cycle route that follows the Rhône, according to the tourist office (our page on the ViaRhôna is in French only for now). For walkers, the sentier de l’eau (“water trail”) links the village of Brégnier-Cordon to the hamlet of Glandieu. The tourist office gives it as 7 km and describes it as short but demanding, with several panoramic views over the Rhône.

Rules to follow

According to the tourist office listing (data of 2 November 2026):

The tourist office explains these bans by the need to protect the site. The rule on dogs is stricter than at the Cerveyrieu waterfall, where they are allowed on a lead: if you are travelling with a pet, make arrangements before you come.
