Top 4 Caves グランドフォンテーヌでの

Water flows from the cave portal here. The large, dry cave entrance is a little higher up. To get there, go back a bit and head uphill at the fork. You can enter this cave via a rock staircase. After a few meters, you can't go any further without getting wet. So turn around and, entering through the large cave portal above, you'll eventually descend back down to water level within the cave.

Well-kept dinosaur park with moderate admission. A combination ticket including the cave can also be purchased (7 degrees). The circular route is about 2km and can also be easily managed with prams. Have fun 🦕

The Trou du Creugenat is a karst hole in the Ajoie from which water emerges and which creates a temporary river, the Creugenat, during floods. The periodic lake forms between 4 and 10 times per year, the river is sometimes only visible for a few hours, sometimes over a week. The flow can reach 15 to 20 m3/s. The water follows the Courtedoux plain and flows into the Allaine at Porrentruy. When dry, the depth of the hole is clearly visible - simple steps lead to the bottom, and a thick rope helps you climb up or down. There is a water level gauge on the side of the rock walls and you can clearly see the mud traces of the last floods. In the immediate vicinity of the hole there is also a picnic area with a table and benches, as well as an improvised fire pit. A meadow path leads from the bike path to the hole.

An adventurous path leads through the small gorge. There are several small caves along the way and the highlight is to climb the steep step with the help of three solid wooden ladders. Only feasible for dogs if you can carry them or take them piggyback. The slippery round wood of the ladders gives even very skilful dog paws little support, so the four-legged friend needs support.
