A pass with little crowds (end of April 2024). The road is open despite the signs (no snow removal). The bitumen is correct, average in places (mounted in Gravel). A few very steep slopes with a small flat area which allows you to breathe on the Charteuse side. No infrastructure at the top. Road and bitumen in good condition on the St-Pacrasse side.

Nice little descent to learn how to position the front wheel correctly, while being careful on certain sections to ensure that the child does not pick up too much speed or panic (risk of falling on the left of around 3m at certain locations).
