Cape Cod’s 559.6 miles of pristine coastline offer some of the most beautiful beaches in the world, especially those along a 40-mile stretch of unspoiled sandy beach in Outer Cape Cod known as the Cape Cod National Seashore.

This location on the wallpaper shows gentle waves at high tide and sandy tidal flats at low tide. Kids love playing in the gently sloping waters of this beach, and rock pools at the shoreline are home to hermit crabs, clams, and other small sea creatures.
