Welcome to the U.S. National Arboretum

The grounds of the U.S. National Arboretum are open from 8 a.m. to 5 p.m. every day of the year except for Christmas Day. The National Bonsai & Penjing Museum is open 10 a.m. to 4 p.m. daily. Admission to the grounds and museum is free and no tickets are needed. Please note that after 2 p.m. on weekdays, all cars must enter via New York Ave.

If you have not yet been vaccinated, please wear a mask and maintain social distancing .

The Administration Building is currently closed to the public. Restrooms are available in the Arbor House near the R Street gate, in the Asian Collection, and near the Azalea Collection.

Look for an orientation sign in parking lots for a map and other information. Visitor guides are not currently available. The Arboretum’s free app, available in the App Store and Google Play, is the best way to explore with maps, a plant finder, and specialized tours.

Thank you for visiting and for helping to keep staff and fellow visitors safe!
