Summit North Marina, on the C&D Canal, is Linda and Harold Grays’ pick for best marina, largely because it sits on a quiet inlet on the canal between the Chesapeake Bay and Delaware River. The marina is near Lums Pond State Park and several golf courses, including Back Creek and Frog Hollow in Middletown. “We are currently the only marina on the canal in Delaware that sells fuel,” says manager Chris Lloyd. In addition, Summit operates Aqua Sol, a Cuban- and South Beach-inspired restaurant that overlooks the marina. Aqua Sol’s patio pumps with live music, and great martinis are poured, all in a Miami-style atmosphere.
