We brought our bikes along and hoped to explore the whole park; however, it was 95 degrees and the water looked inviting! The beach is clean and sandy with minimal rocks and shells. Two suggestions... The shelter offers clean restrooms and changing areas on one side of the building and a snacks on the other. When entering the beach parking lot from the main entrance, keep in mind that the shelter is on the right side if you plan to take advantage of its amenities; otherwise, parking extends far from the building and can be a hike in the hot weather. Secondly, since traffic into the area can be horrendous, arrive early to avoid the traffic jams. Cape Henlopen is an amazing bargain considering the only cost is park entry or an annual pass.
