10 Destinations That Are Natural Optical Illusions

7. Underwater Waterfall, Mauritius

Mauritius is an island country located on top of the Mascarene submarine plateau. Off the Mauritian coast is one of the most stunning natural optical illusions: an underwater waterfall. Yep, that’s right!

While there are geological explanations to justify the interesting phenomenon, what appears to be a waterfall deep inside the ocean isn’t actually water at all. In fact, the ocean currents push the sand off the plateau, creating the illusion of an underwater waterfall.

This means that those swimming there don’t have to worry about sinking into a deep and dark abyss—they can swim over the „waterfall”, as it’s only an optical illusion. If you go there, make sure you bring your camera with you!
