My family rolled into the gorgeous town of Duluth last August on our summer road trip, and we were all really excited about our Lester River train tour with North Shore Scenic Railroad, which we had booked well in advance. As it turns out, it was a sub-par experience and the worst thing we did during out stay in Duluth. The train goes really slowly, and never leaves Duluth. Much of the ride is in the middle of residential Duluth, and not by Lake Superior as expected. The Lester River Gorge is an insignificant little canyon running through the city. The train ride was around one and a half hours long, and that was with a ten-minute delay for it to switch tracks. It was extremely crowded, mainly with loud children. We were waiting for the end the whole time. Duluth is an absolutely spectacular city, and your time here would be much better spent pretty much anywhere else. I'd personally recommend spending most of your time in Canal Park, as the Aerial Lift Bridge is a fantastic sight, and the park contains enough attractions, restaurants, and accommodations to enjoy a happy stay there.
