Welcome to the U.S. National Arboretum
General Information
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 except for federal holidays from November through February. Admission to the grounds and museum is free and no tickets are needed.
Beginning on Thursday, March 27, there will be some changes to traffic patterns at the Arboretum. Most notably, some roads that are normally open to two-way traffic have been temporarily converted to one-way. Spring is the Arboretum’s busiest time of year. With more cars and pedestrians sharing our roads, these changes help keep our visitors safe. We anticipate resuming normal traffic patterns in mid-May. Find more information and view a map at this page. Thank you for driving safely and for spending time with us this spring!
