Welcome to the U.S. National Arboretum

Effective immediately, the outside grounds of the U.S. National Arboretum (USNA) will be open daily to the public from 8 a.m. to 5 p.m. The National Bonsai & Penjing Museum and Administration Building will continue to be closed to the public.

Visitors are still required to follow all posted guidelines designed to maximize the safety and health of all visitors and employees. We will continue to monitor daily visitors and restrict total numbers, as necessary, to ensure everyone’s health and safety.
