São Martinho do Porto

Calm waves roll into São Martinho do Porto — a village in Portugal with a shell-shape bay surrounded by a sand beach. The bay formed when a strip of land along the coast was eroded and then divided by the Atlantic Ocean. Because the opening to the ocean is still relatively small (825 feet or 250 meters), the waves that roll into the beach are almost always calm.
