Understanding Ecosystems for a Sustainable Future

The Reed Education Center and surrounding trailheads are closed to the public until early April 2023 for maintenance. Our trails are open but only accessible from the trailhead near the main campus. Parking is available in the gravel lot on the main campus. Read Plan Your Visit for information on where to park, updated maps and hours, safety, and more.

The Woodlawn History Center is open Fri. & Sat. with extended hours from 10am-2pm!
