A few years ago we were in the Eastern states on a road trip from NY to maine back to NY. While traveling thru NH we made plans to ride the Conway railroad. It was during the fall colors. There are different lengths of trips, depending if you want a scenic trip or if you want to take a train trip from one place to another. It would have been nice had we more time for a longer trip, but I believe we took about a three or so, hour-long round trip. I would recommend this if you’re in that part of the country.
