Delaware Seashore State Park stretches along the coast just north of Bethany Beach, preserving six miles of ocean and bay shoreline between the built-up resort towns. It's the best place in the Bethany area for uncrowded beach access, surf fishing, and quiet walks along the dunes.
The park has ocean swimming areas with lifeguards in summer, a 295-slip marina, boat ramp, and good surf fishing from the Indian River Inlet jetties. A campground runs the length of the park, making it possible to stay inside the park itself rather than in the town. Bay-side access is worth exploring for kayaking and crabbing, with calmer water and excellent birding in the tidal marshes.
