Steady ascent on a good but busy road.
Montée régulière sur une bonne route mais très passante.
Good surface and fairly even slope, with a slight but not nasty accentuation at the end. In the shade of the forest.
Beware, however, of heavy traffic.
Bon revêtement et pente assez régulière avec une petite accentuation sur la fin sans être méchante. A l'ombre de la forêt.
Attention toutefois à la circulation qui peut être importante
The winding nature of this hill makes it a fun ride, but be warned that a lot of cyclists like to go up this hill and the many motorists can quickly become annoyed at being behind 5 cyclists at 20km/h.
Le côté sinueux de cette côte la rend sympa, Attention cependant, pas mal de cyclistes aiment passer par cette côte et les nombreux automobilistes peuvent vite être agacés d'être derrière 5 cyclistes à 20km/h.
