The ‘underwater waterfall’ phenomenon at Mauritius Island

A unique and beautiful ‘underwater waterfall‘ illusion lies off the southeast coast of the African continent at Mauritius Island in the Indian Ocean.

The surreal view’s location, visible only from a precise perspective, rests at the Black River Gorges National Park in Le Morne, on the island’s southwest. UNESCO recognizes the area as a World Heritage site

The spectacular mirage occurs when the sand and silt sediments on the ocean floor sink under the influence of stronger underwater currents between the opening of the reefs.

The scene, in which various sea water colors from light green to dark blue vacillate, resembles the flush of a waterfall cascading into a massive underwater pit. 

One may not see the effect from the shoreline but get an aerial view via helicopter or plane and be prepared to be awed. Tourists claim it looks like an opening to an underworld.
