When crossing into Switzerland, bring your identity papers.

Not recommended in rainy weather. No shelter or water points along the route

Climb to the Grotte du Grenier via metal ladders.

Be careful with the water level of the Doubs, which must not be too high to cross the stepping stones downstream from the Châtelot dam, nor too low (low water levels due to summer drought) to really enjoy the Saut du Doubs on both sides of the border.
