With 3 million visitors packed into just 0.14 square miles, it's the smallest and most congested park in the system (7.0/10 congestion). The tram ride to the top offers sweeping Mississippi River views, and the Museum of Westward Expansion tells compelling stories of expansion and the Dred Scott case.
