Freshwater wetlands once covered a large portion of southwestern Sussex County. Trap Pond State Park retains a part of the swamp's original beauty and mystery, and features the northernmost natural stand of bald cypress trees in the United States. The pond was created in the late 1700's to power a sawmill during the harvest of large bald cypress from the area. The federal government later purchased the pond and surrounding farmland during the 1930's and the Civilian Conservation Corps began to develop the area for recreation. Trap Pond became one of Delaware's first state parks in 1951.

Visitors have many opportunities to explore the natural beauty of the wetland forest. Hiking trails surround the pond, providing opportunities to glimpse native animal species and many flowering plants. Birdwatching is a popular activity and the observant hiker may spot a great blue heron, owl, bald eagle or the elusive pileated woodpecker. More than 12 different duck species can be seen there in winter too. Check out the Bald Cypress Nature Center to get a leg up on species identification.

Canoeing among the bald cypress is a favorite pastime at the park. Rowboats, pedal boats, and kayaks can be rented during the summer season, and the park interpreter hosts narrated pontoon boat tours on weekends and holidays, Memorial Day weekend through Labor Day. Anglers on the water or shore may land largemouth bass, pickerel, crappie, and bluegills. One of the streams that flows into Trap Pond has been marked as a wilderness canoe trail for those who wish to explore the swamp's interior.

The park also boasts a 4.9-mile Boundary Trail that meanders through the forest around the park's 90-acre pond. Picnic areas, which include volleyball courts and horseshoe pits, overlook the pond and three pavilions. A bug-free winter visit to the pond can be at once peaceful and spectacular.
