The Pont de Vert is a picturesque site in the Areuse gorges. It is a stone arch bridge which dates from the 18th century. You will immediately understand the reason for the name of the bridge and the nearby cave as the water reflects the green colors of the moss on the overhanging rocks and trees. A magical place to discover. The perfect starting point for a run with a water fountain to fill your bottle.

The underground mills of Col-des-Roches are a set of mills and underground tunnels built in the 17th century to harness the power of an underground river. A point of interest on your route and perhaps an opportunity to take a break and buy tickets for later.

If you're looking for a fun break from your run in the Swiss Jura, you can visit the Grotte de l'Ours, near Ponts-de-Martel. This is not a deep cave, but rather a large rock formation with several holes that you can explore. The cave is located in a beautiful little gorge, the Combe Poëta, and the path leading there is already an attraction in itself. You can admire the forest, streams and peat bogs all along the way.
