We make the trip across Ontario every summer on our way from Montreal to Lake Superior. It’s a 10 hour drive. Ontario is beautiful. No mountains but thousands of Lakes, rivers, streams, rocky outcrops and Boreal Forests. I feel like I have Jet lag when I get there. It’s exhausting ….. maybe road trips are meant for 20 somethings ??? …. But I also don’t like flying. Maybe the trick is to break it into smaller 3-4 hour driving days ? But hotels are so expensive.
