Off the coast of Mauritius lies a phenomenon that seems straight out of science fiction — an underwater waterfall. While it looks like a massive cascade plunging into the depths of the ocean, it’s actually an optical illusion. From the air, sand and silt drifting off the coastal shelf create the appearance of a waterfall flowing under the sea.
This striking illusion near Le Morne Brabant has become one of Mauritius’s most photographed attractions, drawing travelers from around the world.
How the Illusion Works
The illusion is formed when ocean currents push sand and silt off the edge of a steep undersea shelf. From above, this creates streaks that look like a waterfall pouring into an endless abyss.
