Mont Ross is the highest peak of the Kerguelen Islands in the southern Indian Ocean and the highest point of the French Southern and Antarctic Lands, rising to roughly 1,850 metres. It is a prominent, glaciated volcanic massif within the Kerguelen archipelago.

The mountain is notable for steep, ice-covered slopes and cirques rather than developed visitor facilities; its scale and glaciation are the main natural features of interest. There are no regular tourist services on the island, so landings and climbs occur only as part of organised scientific or expedition trips.

Mont Ross is a volcanic massif formed as part of the Kerguelen Plateau volcanic province. Its present shape reflects volcanic building and subsequent glacial erosion.

Geographically it sits on the main islands of the Kerguelen group in the southern Indian Ocean. The nearest permanent settlement is the French research station Port-aux-Français on Kerguelen.

  • Height: Elevation is about 1,850 metres, making it the highest point of the Kerguelen Islands.
  • Access: Very remote and glaciated - access is normally by organised scientific or expedition voyages to the Kerguelen archipelago.
