Cascade de l'Audeux

Cascade de l'Audeux is a modest but scenic waterfall in the commune of Chaux-lès-Passavant, in the Doubs department, in the Franche-Comté area of eastern France. Tucked into a narrow, wooded valley once known locally as the "valley of the owls," right next to the Abbey of La Grâce-Dieu, it's not as famous as the grand cascades of the Jura further south, but it makes an easy, worthwhile stop for anyone exploring the countryside around Besançon.

Where exactly is the waterfall?

The falls sit on the Audeux river, a tributary of the Sesserant, roughly 30 km from Besançon. The usual approach is to take the D464 toward Bouclans, drive through the village, then follow the D120 to the Abbey of La Grâce-Dieu. A few hundred metres past the abbey — about 400 metres further along the road — there's a car park, from which the main cascade is only around 60 metres away on foot.

What does the waterfall actually look like?

Rather than a single sheer drop, the Audeux tumbles down in stages: over a total elevation change of about 30 metres, the river forms a series of smaller falls, the largest of which is around 15 metres high. The setting is cool and shaded, typical of the tight limestone valleys that cut through this part of the Jura foothills, with rock walls and dense vegetation crowding the streambed on both sides.

Is there a hiking trail, and how long does it take?

For visitors who want more than the short stroll from the car park, several waymarked loop trails run through the area. One of the more popular options covers about 4.5 km and takes just over an hour, with roughly 55 metres of elevation gain. A longer loop of around 7.5 km is a gentler outing of close to three hours, threading through the old valley of the owls, past the buildings of the former Cistercian abbey, and down to the cascade itself. Both routes are generally considered suitable for families and children who enjoy walking outdoors, though a few viewpoints above the riverbed lack safety railings, so some care is needed, especially with young children.

What else is worth seeing nearby?

A few hundred metres from the waterfall stands the Abbey of La Grâce-Dieu, a Cistercian monastery founded in 1139; its walls and history add extra context to a walk through the valley. About five minutes' drive away is the Grotte de la Glacière in Chaux-lès-Passavant, an ice cave often described as the lowest-altitude glacial cave in Europe, sitting at around 525 metres above sea level — natural ice was harvested there commercially until 1887. Between the waterfall, the abbey, and the ice cave, the area around Chaux-lès-Passavant is sometimes recommended as a full-day excursion within the Doubs region.

Frequently asked questions

Is the walk to the waterfall difficult?

No. From the car park near the abbey, the main cascade is only about 60 metres away, so seeing it doesn't require a long walk or any particular fitness level.

Is it suitable for children?

Yes, the shorter loops in the area are generally considered family-friendly, though parents should keep an eye on children near unguarded viewpoints above the river.

How much time should I set aside?

Reaching the cascade and walking back takes only a few minutes, but if you'd like to combine it with a longer loop through the valley and past the abbey, plan for anywhere between about an hour and just under three hours.

How do I get there by car?

From Besançon (about 30 km away), take the D464 toward Bouclans, continue through the village to the junction signposted for the Abbey of La Grâce-Dieu, turn onto the D120, and after passing the abbey drive roughly another 400 metres to the car park by the waterfall.

What else is nearby?

Besides the 1139 Cistercian abbey itself, a short drive away is the Grotte de la Glacière, an ice cave with a distinctive history of natural ice harvesting.
