AnyArt recognizes paintings, sculptures and monuments and tells you their story in seconds, like a personal audio guide. Free for iPhone, iPad and Android.
Free, with a few caveats
Entry to the museum and its permanent collection is free for all visitors. Extras do cost money: the Butterfly Pavilion (a separate timed ticket, so check whether it is open), certain films or special experiences, food at the cafés and parking. There is no general admission ticket to buy.
Hours and closures
The usual hours are 10am to 5:30pm every day of the year except December 25. At some times, especially in summer, hours are extended; check the official calendar before you go. Temporary exhibits or halls under maintenance may have different hours or access.
Do you need to book?
Not for general entry, according to the museum's website. That sets it apart from the Air and Space Museum and the African American History Museum, which require free timed passes. Policies can change for events or capacity, so confirm on the website before you go.
Best time to avoid crowds
- Arrive a few minutes before 10am: the security line is short and you will have the main halls almost to yourself.
- Peak hours are usually 1pm to 4pm because of school groups; the crowds thin out after 3pm.
- On weekdays, Mondays and Wednesdays are typically quieter; weekends and school holidays are the busiest.
- Spring (cherry blossom season) and summer bring more tourists across the whole National Mall.
Getting there and what to bring
The nearest Metro station is Federal Triangle (Blue, Orange and Silver lines), with Smithsonian also close. The entrances are on the National Mall and Constitution Avenue. There is security screening and small bags are best; check current rules on the website. With the AnyArt app you can scan pieces and sculptures to hear their story without renting an audio guide.
