The parking space in front of the city walls of Mont Saint Michel is sometimes also flooded by the tide.
The tides can vary greatly, at roughly 14 meters between high and low water marks. Popularly nicknamed St. Michael in peril of the sea by mediaeval pilgrims making their way across the tidal flats, the mount can still pose dangers for visitors who avoid the causeway and attempt the hazardous walk across the sands from the neighbouring coast. The dangers from the tides and quicksands continue to claim lives.
