About Mont Ross#
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.

There are no regular tourist services on the island, so landings and climbs occur only as part of organised scientific or expedition trips.
