National Seashores are protected coastal areas in the United States, designated to preserve their natural beauty and ecological significance. These areas are managed by the National Park Service and offer opportunities for recreation, education, and conservation. Visitors can enjoy activities like swimming, hiking, and wildlife watching while experiencing diverse ecosystems. Each National Seashore features unique landscapes, including sandy beaches, marshes, and dunes. They serve as habitats for various species, including migratory birds and marine life. Some well-known examples include Cape Hatteras National Seashore in North Carolina and Point Reyes National Seashore in California.
