Planning to drive out to the Canadian side of NF this summer (from Chicago suburbs)... I will not have a lot of time, so I was wondering what is the minimum amount of time that's needed to see it? My plan was to drive out there one Sunday, stay at some motel, then see the Falls on Monday morning and head back home around noon on Monday. So, is about 3 hours enough or will I be missing a lot of good stuff and should plan to stay there the entire day? Thanks.
