The Loue River is a 120 km long river that runs through the Jura Mountains in eastern France. It is one of the main tributaries of the Doubs River, which eventually flows into the Saône River. The source of the Loue River is located in the commune of Ouhans, in the department of Doubs.

The Loue River source is a remarkable natural site that attracts many visitors each year. It is located in a small cave at the foot of a cliff, surrounded by a lush forest. The water gushes out of the cave and forms a small stream that flows down the hillside. The site is easily accessible by a short hike from the village of Ouhans, and there is a parking lot nearby.

The Loue River is known for its crystal-clear water, which is perfect for fishing, swimming, and kayaking. It is also a popular spot for hiking and cycling, as the surrounding landscape is beautiful and offers many trails and paths to explore.
