Thousands of people traveled to Mont Saint-Michel in France on Saturday to see a supertide momentarily turn the ancient abbey into an island.  

This supertide, which happens once every 18 years, was caused by Friday's solar eclipse. The tide reached a height of more than 14 meters, or roughly 46 feet, according to The Australian.  

An exceptionally high tide was seen in all of Northern France, but was most dramatic at Mont Saint-Michel, which is connected to the mainland by a small bridge. On Saturday morning, the high tide momentarily encircled the Mont Saint-Michel, a UNESCO World Heritage Site.  

More than 10,000 tourists from around the world gathered early Saturday morning to watch the rare, natural phenomena, according to The Telegraph.

Surfers and kayakers attempted to catch the high waves created by the tide called "bores."  

"I have never seen the beach this packed down here this early in the season, the conditions are ideal," said surfer Ben Howe, 31, to The Telegraph. "I think Thursday night's supermoon may have affected tidal conditions too as the waves were absolutely mammoth on Friday."

The last supertide was on March 10, 1997, and the next will be on March 3, 2033.
