DuPont Environmental Education Center

Where the City, River, and Marsh Meet

DuPont Environmental Education Center (DEEC) is located along the Christina River and on the edge of the Russell W. Peterson Urban Wildlife Refuge. The refuge is 212 acres of freshwater tidal marsh adjoining the Christina River and is home to wildlife such as American Bald Eagles, Wood Ducks, American Beavers, dragonflies, river otters, and Eastern Painted Turtles. DEEC is open to the public year-round and features a Visitor Center with panoramic river and marsh views, a 10-acre ornamental garden, a quarter-mile handicap-accessible pond loop extending into the marsh, and trailhead access to the newly completed 5.5-mile-long Markell bike/hike trail from Wilmington to New Castle.

DEEC works with the local community as the primary provider of DelNature’s RENEW program and is a member of the Alliance for Watershed Education.
