Smithsonian Museums
Most Smithsonian museums on the Mall do not charge admission. The limit is time and energy: each major building can fill half a day. Security lines form at opening, especially for Air and Space and Natural History.

The two busiest Mall museums; Air and Space may use timed entry—reserve free tickets when required.
The Star-Spangled Banner and presidential artefacts; the Smithsonian Castle visitor centre orients first-timers.
Portrait Gallery / American Art in Penn Quarter, Zoo in Woodley Park, and Udvar-Hazy near Dulles for the big hangars.
Admission is free, but some museums require free timed-entry passes. Hours vary by building and season. Confirm on si.edu before you queue.
A focused day beats a blur of lobbies. Leave buffer for security and the Mall walk between wings.
Lines and school groups build by late morning. Air and Space and Natural History feel it first.
Maps, cafes and a central location between the main Mall museums.
Are Smithsonian museums really free?
Yes for standard entry to the Mall museums. Special tickets or IMAX may cost extra; timed-entry passes are still free when required.
Do I need to reserve?
Often for Air and Space and sometimes others during peak seasons. Check each museum's page.
How many can I see in a day?
Two carefully, three if you are selective. Four is a rush.
Is the zoo included?
The National Zoo is Smithsonian and free, but it is not on the Mall; plan a separate half day.
The Smithsonian Institution was founded in 1846 with a bequest from James Smithson. It is the world's largest museum and research complex, largely funded by the U.S. government and private support.
Mall museums are among Washington's top visitor draws. Policies on timed entry, hours and special exhibitions are set per museum.
