Arriving in an RV in front of the Hérisson waterfalls without having scouted parking is risking driving on narrow roads with a seven-meter vehicle. The site stretches along a narrow valley in the Jura, served by three distinct access points. Not all accept wide vehicles, and only one really allows for overnight stays nearby.
Vehicle Size and Height Barrier: What to Check Before Leaving
Before choosing between the lower or upper parts of the waterfalls, one question arises: what is the actual height of your RV? A satellite dish, a roof air conditioning unit, or a roof box can easily add several dozen centimeters to the size stated by the manufacturer.
In the Jura, some parking areas are equipped with height barriers that physically block entry. Measure your vehicle with all equipment deployed to avoid having to backtrack on a road with no possibility of turning around. This point is regularly mentioned in specialized guides such as Rovee and AiresCampingCar.
If you are looking for a RV parking near the Hérisson waterfall that accepts large vehicles, the parking lot at the Maison des Cascades in Ménétrux-en-Joux remains the most accessible. Improved ground, relatively flat surface, no height restrictions reported.
Ménétrux-en-Joux Parking: Convenient During the Day, Closed at Night
This parking area, located at the bottom of the site, allows you to reach the Éventail waterfall in just a few minutes on foot. The path is accessible, including for families with strollers.
Overnight parking is prohibited between 10 PM and 7 AM, even without deploying external equipment. This prohibition is confirmed by the Trips and Tips site, in an article updated in October 2026.
For a day visit, the place is quite suitable: immediate trail access and enough space to maneuver. In high season, spots fill up quickly. It’s better to arrive early or plan to vacate your spot by late afternoon.
Parking or Camping: The Distinction That Can Be Costly
Have you ever wondered when a parked RV becomes wild camping? The answer lies in a concrete detail: as long as nothing extends beyond the vehicle (no awning, no table, no chairs, no blocks), you are parked. As soon as any external equipment appears, the situation can be reclassified as camping, with the associated penalties.
This distinction, reiterated by the Union of RV Clubs and the French Federation of Camping-Caravaning Associations, applies to all public parking areas in the Jura. No equipment should extend beyond the vehicle outside of a designated area.
Ilay Parking at La Chaux-du-Dombief: The Choice for Late Arrivals
At the top of the waterfalls, the hamlet of Ilay has a free parking area. It provides access to the Saut Girard and nearby walking trails.
Why is this parking area of interest to RVers? Ilay seems the most suitable for arriving late in the day or for a night near the site. The environment is calm, bordered by forest, with partial shade depending on the occupied spot.
- Direct access to the Saut Girard waterfall without descending the entire valley
- Free parking, with no height barrier reported in available sources
The compromise to know: from Ilay, you are at the top of the site. To reach the Éventail waterfall, the most spectacular one, you must descend the entire trail and then climb back up. Allow several hours and a good elevation change for the complete loop.
Hérisson Camping: Sites with Electricity Nearby
The Hérisson Camping, formerly Relais de l’Éventail, is located a few hundred meters from the Éventail waterfall, in the valley. It offers sites with electrical hookups. The management changed in 2021, with a focus on tranquility and nature.
Shade and Thermal Comfort: Clear Differences Between Parking Areas
In summer in the Jura, the temperature inside an RV can vary by more than ten degrees depending on whether the vehicle is in the shade or in full sun. The parking areas do not offer the same conditions in this regard.
The parking lot at the Maison des Cascades, at the bottom, offers limited shade. The improved surface leaves little room for trees. The one at Ilay, at the top, benefits more from the surrounding forest cover, with denser natural shade depending on the chosen spot.
Quick access to the main waterfall from Ménétrux-en-Joux, overnight autonomy in a calm setting at Ilay, equipped sites at the Hérisson Camping: none of these three parking points ticks all the boxes. This is precisely what makes prior scouting essential when traveling in an RV in this Jura valley.
