The Cascades du Hérisson form one of the most celebrated natural spectacles in the Jura département of Bourgogne-Franche-Comté. The Hérisson river descends 280 metres over a 3-kilometre gorge, passing through 31 documented waterfalls and cascades before reaching the valley floor. The trail that follows the gorge — the Sentier des Cascades — winds through dense mixed forest along the riverbank, offering close-up access to falls of varying size and character. The most dramatic is the Cascade de l'Éventail, which fans out over a broad basalt lip in a curtain approximately 65 metres high; it is reached roughly 40 minutes on foot from the lower car park at Doucier. Continuing upstream brings visitors to the Cascade du Grand Saut (60 metres), where the river plunges in a narrow single drop into a clear pool, and to the Cascade de la Gour Bleu, a broader shallow fall above a cobalt basin. The full circuit from the lower car park at Doucier to the upper car park near Bonlieu and back takes approximately 4 to 5 hours at a moderate pace. Shorter out-and-back options are possible: the Éventail alone can be reached and returned from in under 90 minutes. Trail conditions can be slippery after rain, and sections close to the water involve scrambling over rocks. The trail is free to walk. Swimming is not permitted in the gorge pools. The best water flow is in spring from snowmelt, typically April through June.

Tips for visiting
- Start from the lower Doucier car park to walk uphill with gravity in favour on the return descent.
- Wear hiking boots or trail shoes — the path is rocky and muddy after rain, particularly near the falls.
- Carry water and a snack as the trail has no refreshment stops once past the first car park area.
- The Éventail waterfall is reachable in under 90 minutes round-trip for visitors who cannot complete the full circuit.
- Avoid weekends in July and August when parking at Doucier fills by mid-morning; arrive before 09:00.
When to visit
April through June offers the highest water volume from Jura snowmelt, making the falls most dramatic. September brings autumn foliage and fewer crowds. Avoid mid-July to mid-August weekends when parking and trail congestion is heaviest.
Accessibility
The Sentier des Cascades involves uneven rocky terrain, steep sections, and natural steps. It is not accessible for wheelchair users or pushchairs. Visitors with limited mobility can reach the first viewpoint near the lower car park, which provides a partial view of the lower falls.
