A 10 km climb from the small roundabout in Châtillon, it's more like 14 km from the Nantua road or the center of Bellegarde. The gradient is fairly steady, ranging from 5.5% to 7.2%, with about ten small steep sections at +8.5%. Very quiet, with very few cars. The road is generally in good condition, but nothing more. There are some beautiful views along the way.
