Difficult route if you are there to ride. I do not recommend it to cyclists other than touring cyclists.

A lovely walk reminiscent of the old route of the Bievres Valley. Luckily, we avoided the extension of the A10 to the ring road! A fun route, but watch out for pedestrians and cross streets...

Typical Île-de-France coastline. Approximately 1km at an average gradient of 5-6%. It climbs to 7-8% on the last bend before reaching the village of Magny. Often used to get to the Chevreuse Valley from Paris/Versailles. There are a few cars, but the road is wide enough for overtaking.

a fairly pleasant hill. You can turn around at the traffic lights at the top, go back down and take the cave towards Gif
