Illusional Waterfall, Underwater geological formation near Le Morne, Mauritius.
The Illusional Waterfall is an underwater geological formation near Le Morne created by sand deposits carried by ocean currents into deeper waters. From above, the flowing sand creates a visual effect that resembles a massive waterfall cascading down a submarine cliff.
The formation lies near Le Morne Mountain, which held refuge for escaped slaves during the 18th and early 19th centuries. The coastal region's geological features have evolved over time through natural ocean processes.
Local communities maintain oral traditions about the geological formation, connecting it to stories of marine navigation and environmental patterns.
Helicopter tours are the best way to view this formation, as it is only truly visible from above where the optical effect becomes clear. Early morning flights tend to offer the clearest visibility and the best lighting conditions for seeing the sand movement patterns.
The sand flows over a submarine cliff edge that drops steeply into the Indian Ocean, creating an optical illusion so convincing that visitors often mistake it for an actual waterfall. The effect changes depending on the time of year and the strength of the ocean currents.
