Le Donjon, Mountain summit in Kerguelen Islands, French Southern and Antarctic Lands.
Le Donjon rises 594 meters above sea level in the southern Indian Ocean, featuring steep rocky slopes and exposed surfaces shaped by strong winds.
The summit received scientific attention during the first French expeditions to the Kerguelen Islands in the late 18th century for geographical mapping purposes.
Scientists from international research stations regularly monitor the summit area to study climate patterns and geological formations in sub-Antarctic environments.
Access to Le Donjon requires official permits from French authorities and specialized equipment due to extreme weather conditions throughout the year.
The summit area contains specific volcanic formations that provide geological evidence about the formation processes of the Kerguelen archipelago.
