take hwy 40w to three rivers then 155/55 north to parc de la mauricie. This a federal park with a 70km stretch of non stop turns. ususaly costs about $5 to get in not many park rangers but make sure to ask at the gate if there are any cops doing radar that day. Learnt from exp. Just before exiting the park there is a waterfall to cool off and check out the chiquitas(sweet), then turn around and go back the way you came. The road is surprisingly smouth for a quebec rd.
I'm In! This road is amazing I'll get 4-5 of my buddies to come too. There's always alot of spotbikes up there. Last time I was up there, there was a group of maybe 15 girls on sportbikes and they were pretty fast! I was very impressed.
