The terrain rises from the coastal plains to the central plateau, where it reaches an altitude of 670 meters. The island’s highest peak, Piton de la Petite Rivière Noire at 828 meters above sea level, is located in its southwestern part. It forms part of the Black River mountain range.
There are two other mountain ranges in Mauritius: the Moka-Port Louis and Grand Port-Savanne. The Moka-Port Louis range includes the peaks of Pieter Both (820 meters above sea level) and Le Pouce (811 meters above sea level), the second and third highest peaks respectively. Both are more famous than the Piton de la Petite Rivière Noire in the southwest.
