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.
