The underwater waterfall in Mauritius is a fascinating phenomenon that draws hordes of travellers from all over the globe. It’s stunning beyond measure but it’s really its rarity that makes it so special. Besides the bragging rights, you’ll have gorgeous photographs to feed your social media.

Viewing it from above will have you in awe but, like most natural wonders of the world, nothing beats seeing it up close.

There’s also a story behind the waterfall, a local myth intertwined with this geological wonder, creating even more curiosity and mystery surrounding its existence.

Legend says that after the 1835 abolition of slavery, authorities were to inform a group of escaped slaves of their newfound freedom. However, there was a miscommunication, and the enslaved people chose to dive off a cliff to their demise rather than accept slavery.

But what’s mind-blowing is that this mass suicide occurred before discovering the underwater waterfall, leading many locals to believe that the two were somehow connected.

Background and Information for the Underwater Waterfall, Mauritius

Sorry to spoil the illusion, but the underwater waterfall of Mauritius is not even a waterfall. It’s a natural optical illusion caused by moving sand — it’s easy to fall for it, though (get it?).

To give a straightforward explanation, the ocean currents collect and drive coastal sand and silt off Mauritius’ southern tip into the ocean’s depth. This creates an “underwater waterfall”. It’s a dramatic scene that resembles a part of the island sucked down a drain.

Now I’ve got that out of the way, let’s take a deep dive into the nitty gritty.
