Le Morne Brabant on the southwest coast of Mauritius has a cool optical illusion offshore: water flowing between two reefs pulls sand out to sea, giving the appearance of an underwater waterfall.
YouTuber RubenMRU says:
So the day after my birthday this year saw one of my dreams come true… Vassen Kauppaymuthoo of Delphinium Ltd took me out on a boat trip to the south west coast of Mauritius and we've captured the now famous Underwater waterfall of Mauritius… Now it's not really a waterfall, it only appears to be one from above – this illusion is caused by the trails of sand on the sea floor, being dragged away by water going between the opening in the reefs
