Welcome to the U.S. National Arboretum

The Arboretum grounds are open every day of the year except December 25 from 8:00 a.m. to 5:00 p.m. The National Bonsai & Penjing Museum is open from 10:00 a.m. to 4:00 p.m. daily except for federal holidays November through February, so plan to visit this collection first if you visit late in the day. Please see our Hours and Directions page for additional information. We look forward to seeing you at the National Arboretum, where science meets beauty.
