DuPont Environmental Education Center is a refuge containing 212 acres of freshwater tidal marsh adjoining the Christina River and is home to many birds such as American Bald Eagles, Virginia Rails, Belted Kingfishers, Wood Ducks and a wide variety of other nesting and migrating species. Also, American beaver, river otter, and Eastern Painted Turtles can be observed in the river and tidal pool. In summer, several kinds of colorful dragonflies swoop over the marsh in search of small insect prey. The center 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 7-mile long Markell bike/hike trail from Wilmington to New Castle.
