Smithsonian Environmental Research Center

Understanding Ecosystems for a Sustainable Future

The Reed Education Center and Java Trail are closed to the public from Jan. 30 through Feb. 4 for maintenance. Public composting toilets and all other trails will be open during normal hours. The Woodlawn History Center is open Fri. & Sat. with extended hours from 10am-2pm!

Please do a health self-check before arriving, and stay home if feeling sick. Read Plan Your Visit for information on where to park, updated maps and hours, safety, and more.
