A supertide has briefly turned France’s famed Mont Saint-Michel into an island, delighting thousands of visitors who came to see the rare phenomenon.

The so-called “tide of the century”, which actually happens every 18 years, raises sea levels along the northern French coast, but is especially dramatic at the Unesco world heritage site that is normally linked to the mainland by a narrow causeway at high tide.

The peak of the supertide on Saturday morning, said to have risen at the pace of a horse’s gallop, turned the outcrop briefly into an island, while the day’s low tide allowed people to walk on the expansive flat seabed once again.
