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. Admission is free and no tickets are needed. Please note that after 2 p.m. on weekdays, all cars must enter via New York Ave.
All staff and visitors must wear masks at all times while at the U.S. National Arboretum, whether indoors or outside.
The National Bonsai & Penjing Museum and the Administration Building are currently closed to the public. Restrooms are available in the Arbor House near the R Street gate, in the Asian Collection, and by the former Grove of State Trees.
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!
