More than beautiful beaches highlight the 5,193 acres here. A 3-mile hiking trail passes a World War II observation tower, which you can climb to the top for a stunning 360-degree view, and there's more World War II history at Fort Miles Historic Area. You can also observe the marine life that inhabits five 1,000-gallon tanks at the Seaside Nature Center aquarium. Activities include kayaking, fishing from the pier, basketball courts, and an 18-hole disc-golf course.
