The source of the Loue River is announced by the rushing water even before you see it. It's impressive and magical to stand beneath the 150-meter-high cliffs and watch the river rush out of its cave.

This cave is superb. It has been unblocked several times and archaeological traces trace the human presence from the Neolithic to the present day. Bring a headlamp to explore this cave and its many rooms in more depth, but first find out about periods of calm and lethargy for the bats (you are in their home there)

This cavern is impressive, the immense cliff seems to crush this “small” opening in the wall, from which clear waters gush. The lights and the tranquility of the place are remarkable. Consider bringing a headlamp to explore the caves a little more. Climbing enthusiasts will notice some equipped routes with quite an overhang.

One of the largest springs in the entire Jura region. Very impressive after long periods of rain.

This is truly a magical place! A whole river that comes straight out of the rock. There is a huge parking lot just a few hundred meters away, which takes some of the magic out of the place. So I would recommend visiting this place out of season. And instead of starting from the parking lot, take a long walk along the surrounding hiking trails, which are definitely worth it.

On a hike, you have to go to the source of the Loue by climbing the Nouailles gorges. It's a wonderful hike but you have to be well-shod and to be avoided in wet weather.

At the source of the Loue, you are faced with a steep rock wall 150 meters high, which forms a spectacular cirque. It is from this monument that the Loue springs. The site is easily accessible and is via marked GR trails.
