Île-de-Bréhat in France splits into two islands at high tide.
Located just off the northern coast of Brittany, Île-de-Bréhat is actually a small archipelago. At low tide, the main island and its rocky northern neighbor are connected by a sandy causeway. But when the tide rolls in—dramatically, thanks to the region’s extreme tidal swings—they become two distinct islands! It’s like nature’s version of a magic trick, played on a charming seaside village.
