The climb seems to be open again in June 2025. I did detour to be sure, but I didn't see any closure signs. The climb itself is not mega exciting, although there are small steep bits in it. It is a very beautiful climb through the Jura, though

Fine/fun climb to do by road bike, good tarmac and very little traffic and nice through the forest. The descent is also nice.

Not too tough climb, a nice runner. Above all, not too busy and beautiful scenery. Over the summit you can continue in different ways and dive deeper into the Jura. It only gets more beautiful.

Nice long pass with variations in slope, quiet in the forest. Good surface, a bit steep at the end.

Nice climb without heavy percentages. Kilometres to the top are marked with percentages. Nice for the distraction. Climb is mainly through the forest.
