The Piton des Neiges, once an active volcano, poured lava flows which retreated to create a cliff that is now the region of the Pointe au Sel.
Just outside of Saint-Leu, located on the coast of the town, there is a very popular natural curiosity: the blow hole. Under the pressure of waves, a strong jet of spray several metres high ejects through a small funnel-shaped collapse in the arch of this underwater cave. The magmatic particularity of the coastline is at the origin of this impressive phenomenon. During strong storms of extreme intensity, it is a place of grandiose natural spectacle. To get there, go south towards Saint-Leu where a sign will indicate Le Souffleur (The Blower), on National Route 1.
You can get there by car: parking has been arranged for visitors and a staircase will allow you to access the site.
