Sault Ste. Marie to Montreal

Hwy 17 takes you from the Soo to Ottawa and then on to Montreal. It’s a nice drive but not a lot to stop and do along that route. Not sure how much time you want to spend but i would suggest a stop in Sudbury. They have a nice bird sanctuary, nickel mine tours and the science north museum which is amazing. From there if you go a little south I would suggest going hwy 69 through the French River area and stopping at Grundy Lake provincial park. Rent a canoe and paddle the lakes. From there go through Huntsville (nice little touristy town) and camp at Arrowhead pp. Then take hwy 60 through Algonquin park. Several campgrounds to choose from there. Great sightseeing, hiking, fishing, birding etc at each of them. Maybe spot some bears and moose. It would be a longer, less direct route but well worth it in my opinion. If anything, go through Algonquin. You will need reservations at each place though.
