Situated at the mouth of the Delaware Bay sits Cape Henlopen State Park and its 6+ miles of coastline. The “Point” of Cape Henlopen, where the Delaware Bay meets the Atlantic Ocean, shaped the history of this landscape. For millenia, native people lived off the land’s abundant and rich resources and in the late 1600s, William Penn’s family granted the land and allowed citizens to harvest many of the same resources. The area’s strategic position led to the construction of Fort Miles during World war II with its iconic fire control towers along the Atlantic coast and, which served as a federal defensive site, training area and testing location both during and after the war. A diverse collection of habitats makes up the coastal ecosystem of Cape Henlopen State Park. Barrier dune, coastal beaches, and maritime forest are home to many species of plants and animals. Visitors can visit the Seaside Nature Center to participate in an interpretive program or learn about the park’s native plants and animals.

Water, Beaches, and Trails
Cape Henlopen's beaches attract thousands of visitors who enjoy everything from ocean swimming, boating, fishing, and kayaking to clamming, paddle-boarding and wind-surfing. But Cape Henlopen offers more than just the ocean and bays. The park's premiere trails offer hiking and biking exploration.

A designated swimming beach, accessible from the Lewes entrance to the park, provides lifeguard patrols between Memorial Day weekend and Labor Day (schedule may vary depending on staff availability).

Mobi-Mat equipment, consisting of three 30-foot mats allowing those in wheelchairs and power chairs to access the beach from the boardwalk, is also available at this location.

Camping and Cabins
Cape Henlopen's campground, set among pine-covered dunes, now includes 2-point hookups, 100-amp service on several sites, and sites to accommodate larger rigs. Twenty walk-in tent sites lie adjacent to the Waking Dunes Trail. Twelve camping cabins -- two-room individual cabins that offer an outdoor spigot and fire ring for cooking and share a communal bath house -- offer an economical alternative for vacationing at the beach.

Fort Miles Museum and Historic Area
During World War II, the Delaware River was a chief priority for defense planners because of the access it afforded to the giant trade centers of Wilmington, Philadelphia, and beyond. Fort Miles, located in what is now Cape Henlopen State Park, was a key piece of the nation's coastal defense at that time.

Seaside Nature Center
The centerpiece of the newly-renovated Seaside Nature Center is a 495-gallon two-level touch tank, complete with viewing windows that allow visitors to see stingrays, horseshoe crabs and other species in the tank while they’re underwater. The nature center also features five 1,000-gallon tanks with local fish, exhibits that explain the different habitats within the park, a live Osprey cam provided by the Friends of Cape Henlopen (April through August), and a gift shop. A wide selection of activities and programs for children and adults are led by Seaside Nature Center staff each week.
