How to Get to National Museum of Natural History #

The National Museum of Natural History sits on the National Mall in Washington, D.C. The easiest way is by Metro: take the Blue, Orange, or Silver line to Smithsonian station - the museum is about a 5-10 minute walk across the Mall from that station. Many downtown bus routes also run along the Mall; driving and parking are limited, so transit is recommended.

Tips for Visiting National Museum of Natural History #

  • Arrive at opening on weekdays to see the Fossil Hall and the Hall of Geology, Gems and Minerals (home of the Hope Diamond) before school groups and tour buses arrive.
  • Use the Mall-facing Constitution Avenue entrance for the most direct access to the main halls and to cut walking time-once inside, head to popular exhibits first then circle back to quieter displays on upper and lower floors.
  • Many visitors overlook temporary and smaller-specialty exhibits; check the museum's daily map on arrival and reserve timed-entry or special exhibit tickets in advance when available to avoid lines.
