Explore the Marsh at DuPont Environmental Education Center
The DuPont Environmental Education Center (DEEC) is a gateway to one of Wilmington’s most remarkable natural spaces, connecting the city, river, and marsh. Located along the Christina River at the edge of the Russell W. Peterson Urban Wildlife Refuge, DEEC is surrounded by 212 acres of freshwater tidal marsh teeming with life, including Bald Eagles, Wood Ducks, River Otters, and Eastern Painted Turtles.
The center features panoramic river views, a 10-acre ornamental garden, and a quarter-mile accessible pond loop trail extending into the marsh. It also serves as the trailhead for the 5.5-mile Jack A. Markell Trail, connecting Wilmington to New Castle.
DEEC plays a leading role in DelNature’s RENEW program and is a proud member of the Alliance for Watershed Education.
DuPont Environmental Education Center is a partnership with the Riverfront Development Corporation.
