Crescent-shaped Corporation Beach, hugging Cape Cod Bay, is a popular spot on hot summer days. The curve of the beach forms a tidal pool that's perfect for children. The warm, calm bay water is great for swimming at high tide. At low tide, the water recedes and reveals huge flats great for exploring and walking. It is near Sesuit Harbor, and beachgoers can pass the day watching pleasure boats sail the bay. Corporation is popular with children and their families, especially during low tide.
