The Formica Leo is small a volcanic Cratère located at the foot of the Piton of the Furnace, the active Volcan of the island of the Réunion.

Below located the No Bellecombe in the Enclosed Fouqué, the crater owes its name with its resemblance to the holes dug by a species of Fourmi.

Culminating with 2.202 meters of altitude, Leo Formica was born from a eruption of 1753.
