The "Children's Rights Trail" is a project of the Pérène Foundation, located near Saulcy in the Jura region, which aims to raise awareness among children and adults about children's rights. It is a trail of approximately 1 km, marked with artistic works inspired by the rights and responsibilities of children, which leads to the Ferme de la Combe es Monin. The project began in November 2010 with a reflection phase involving students, and the creation of the works took place from January to June 2011. The trail has an ethical, cultural, pedagogical, and educational scope, addressing the principles of judgment and conduct based on children's rights. It also provides a space for reflection on what is socially acceptable and the possible actions for each individual.

Imposing grotto and at the same time a place of pilgrimage. Here you should switch from the hiking trail near the bridge to the road and pause for a moment and enjoy the gentle coolness and refresh yourself with the water from the Karlsquelle (which is said to have healing powers). A small karst spring arises inside the cave. The water flows as a trickle from a stalagmite into a shallow basin. There is a crucifix under the entrance arch of the grotto, dedicated to Saint Columba of Sens, a 3rd century martyr. The place has been the destination of a pilgrimage on August 15th since the 13th century. The spring water is said to have miraculous healing powers.
