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.

Statement from the Agricultural Research Service
Policy on Mask Use and Social Distancing

On January 20, 2021, President Biden issued an Executive Order requiring masks and social distancing in Federal buildings and on Federal lands. The new administration is currently developing a COVID-safety plan for the U.S. Department of Agriculture that will prioritize the health and safety of all federal employees and contractors, as well as visitors to federal facilities and land. While this safety plan is being developed, the U.S. National Arboretum will follow the advice of public health and science experts, by requiring all USNA visitors and employees to wear a mask, maintain social distance while on USNA property, and to take other related precautions recommended by the U.S. Centers for Disease Control and Prevention.
