The amplitude of the tides in Saint-Malo can reach spectacular levels, sometimes more than 12 meters. The difference between high tide and low tide is considerable, transforming the landscape in a few hours. At low tide, the beaches and rocks are exposed for hundreds of meters and at high tide, the water rises to the foot of the ramparts and sometimes even submerges them slightly. Be sure to watch Storm In Saint-Malo if you want to see more of this coastline.
