Travel from the airport to the Gateway Arch was easy. You park in a nearby parking garage and it is a short picturesque walk to the Arch. We visited the museum, which is free, as well as the gift shop, and purchased tickets for the tram. The departure time for the tram was a couple hours away, so we walked down to the river and ate at the River Cruise dock.
When we finally got in line for the tram, we had to leave our child's stroller behind. You receive a short history before boarding the tram. The tram itself is a bit cramped but was a very exciting ride. Once at the top, there is flight of stairs. The view was spectacular.
