Gateway Arch National Park

St. Louis city's violent crime rate of 473.6 incidents per 100,000 residents in 2023 is the clearest safety concern for visitors to Gateway Arch National Park — well above the national average and the dominant risk in this urban setting. The park sits directly within the city, meaning the surrounding streets carry that elevated risk, particularly after dark. Weather hazards logged in the data are comparatively minor, with just five recorded events including hail, thunderstorm wind, heavy rain, and one flash flood.

Keep your visit centered on the riverfront park grounds and the Arch complex itself, where ranger presence and foot traffic are consistent deterrents to crime. Walk to your car in groups after evening events and use the well-lit Jefferson National Expansion Memorial parking areas rather than street parking in less-trafficked blocks. A portable phone charger is worth packing so you can contact park staff or emergency services immediately if something feels off.
