I live about 45 minutes from the BRP and am up that way a lot. Have ridden most of it at one time or another and never get tired of the place. Be advised , watch your fuel. There are almost no places directly on the BRP to buy any. I also recommend you check their web site and road closure/detour info before you start your trip. We had some pretty severe weather for the region this winter and there are some closures of section. Doesn't really matter because the whole area is motorcycle friendly and any road around here is as good or better than the BRP.
