Go straight into Saint-Alexis-des-Monts. At the 4-way stop sign, take a right and stay on Rue Ste-Anne and you will be on the route. The route ends at the Poste D'Accueil Pins Rouges.
Beautiful cliffs and mountains on your left as you follow a beautiful river on your right in the middle of a forest. You won't be disappointed!
Has very good road conditions and a lot of slow to moderate speed twisties (~40-70 kph). Just beware of the blind corners, especially in the hilly section, and respect the white and red chevrons sign before the decreasing-radius blind turn!
There are two big lakes nearby to explore if that's your thing and also the end of the route leads right into the Mastigouche Wildlife Reserve.
Very good road conditions. My 2nd favorite twisty road, due to the road conditions and amount of twisties, but not as good as the Parc National de la Mauricie, which has even much better road conditions, is twice longer and has lots of fast sweepers (100+ kph!).
