Soak in bird's eye views of the amazing mountaintops of the historic Lackawanna River Valley. On your way into Scranton, stop and stretch your legs out at the Steamtown National Historic Site. It's the only site in the country dedicated to steam locomotion, complete with well-preserved examples of this old technology on display—and in action. Whistles and bells, steam and oil, and earth-shaking rumbling of these huge engines will make this a highlight of your journey.
