Andeor

The underwater waterfall of Mauritius

Off the Le Morne peninsula, the seabed seems to plunge over the edge of an underwater cliff. It is an illusion created by sand and silt flowing off the island's shallow shelf into deeper water, and it only reveals itself from the air.

Good to know

What you are looking at

Mauritius sits on a shallow ocean shelf. Around Le Morne, currents drag sand and silt off that shelf towards deeper water, and from above the moving sediment reads as a waterfall pouring into the deep.

Why a boat is not enough

The effect depends on looking down through the water from altitude. From the surface the same spot is simply a beautiful stretch of lagoon edge, which is why every viewing is a flight.

Your two options

A helicopter circuit from Bel Ombre reaches the waterfall in a flight of about fifteen minutes. The seaplane from Grand Gaube reaches it on its hundred minute journey around the east and south coasts.

Common questions

Is the underwater waterfall real?

There is no actual waterfall under the sea. The image is created by sand and silt flowing off the coastal shelf into deeper water. The illusion itself is genuinely there and reads clearly from the air.

Can you see it without flying?

No. Satellite images show it, but from a boat or the beach the angle is too flat. Seeing it in person means a helicopter or seaplane flight.

Where exactly is it?

Off the Le Morne peninsula at the south west corner of Mauritius, just beyond the lagoon that surrounds the mountain.
