Playing in the sand NPS. All NPS. Spending time on the sandy beaches of Cape Hatteras National Seashore is a memorable experience, no matter your activity level. You can enjoy walking along the nearly 70 miles of beach, sitting around the crackle and warmth of a beach fire in the evening, flying kites in the warm summer breezes, picnicking with your favorite food, searching for shells washed ashore, sculpting sand into works of art, or just relaxing on the warm, golden sand.
