The Chute Blanche is a super nice and scenic park and huck on the Mistassini river. It gives a nice alternative during the summer when everything is too low. However, it is probably closer to the north pole than anything else. You will have to be a highly motivated driver to go run this waterfall. However, You will be reward of that drive with the cleanest double drop that Quebec has to offer. A 20 footer into a 50 footer. We did not run the first drop on our trip but maybe with a bit more water it would be runnable.
Scouting is super easy on river left, but you will have to ferry above and be a little creative to put on above the second one. On our trip, we used the trail of a cabin on river left not far after the drop to get back to the car.
