Splash pads in Lewes, Delaware

Cape Henlopen is one of the great Mid-Atlantic state parks, and the spray park is the cherry on top of a beach-and-bunker day. After exploring the WWII observation towers and the Seaside Nature Center touch tank, the kids cool off in the free spray ground while you reset under the pavilions. Vehicle entry runs $10 in-state and $20 out-of-state, but it's the only fee — splash play is free. Park early on summer weekends; the lots fill by 10am. Coastal Delaware sun is brutal — water shoes and SPF 50 minimum. Hurricane season (June–November) closures happen; check the DNREC park alerts page before you drive over.
