It's a very good climb on the Plateau de Saclay, with the last section in the forest very pleasant. The main drawbacks are that you have to cross the Avenue du Général de Gaulle (lots of traffic) and that there are a number of one-way streets for cars (but authorised for bikes).... read more

C'est une très bonne côte du plateau de Saclay avec la dernière portion dans la forêt très sympa. Les gros point noir sont qu'il faut traverser l'avenue du général de Gaulle (beaucoup de trafic) et qu'il y a plusieurs rues en contre sens pour les voitures (mais autorisées pour les vélos).

The Butte Bois Persan climbs quite steeply. It's a real little hill that defends itself and knows how to take your breath away if you press hard on the pedals.

Here, the locals have all opted for electric bikes...
The road is clean and pleasant. It runs alongside and borders the Bois d'Orsay. Not much traffic. Not much to get excited about up there, but I'm not sorry I came.

Elle grimpe plutôt sérieusement cette Butte Bois Persan. C’est une vraie petite côte qui se défend et sait nous essouffler si l’on appuie fort sur les pédales.
Les 13％ sont bien au rendez-vous.
Ici, les habitants ont tous opté pour le vélo électrique…
La route est propre et agréable. Elle longe et borde le bois d’Orsay. Peu de circulation. Pas grand chose de bien motivant là-haut mais je ne regrette pas d’être venu.
