Another rock arch on the way through the Gorges de l'Areuse / Areuse Gorge. One of the most beautiful gorges in Switzerland.

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.

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.

While many of the listed sites are accessible, the broader region around Les Ponts-de-Martel does feature more challenging natural phenomena. For instance, the Glacière de Monlési Ice Cave, though not a show cave, is a significant natural ice cave that requires proper equipment and guidance for exploration due to its shafts and ice-filled chambers. Most publicly accessible sites are less about deep caving and more about exploring grottoes and rock shelters.
Some natural rock formations and shelters, like the Baume du Four Shelter, are noted as dog-friendly. When visiting natural outdoor sites, dogs are generally welcome, but always ensure they are on a leash and check specific rules for any indoor or managed attractions like the Underground Mills.
For natural grottoes and rock shelters, comfortable hiking attire and sturdy shoes are recommended, as many are accessed via trails. For sites like the Underground Mills of Col-des-Roches, the temperature inside is consistently around 7°C (45°F), so bringing a warm jacket is advisable even in summer.
Parking availability varies by specific location. For sites within gorges or along hiking trails, you'll typically find parking at trailheads or nearby villages. For attractions like the Underground Mills of Col-des-Roches, dedicated parking facilities are usually provided. It's best to check the specific highlight page or local tourist information for detailed parking instructions.
