Among Earth’s most isolated territories, the Kerguelen Islands are a sub-Antarctic archipelago of stark beauty and extreme conditions, administered by France and home only to scientists and military personnel.
At a glance
The Kerguelen Islands—also called the Desolation Islands—comprise Grande Terre, the main island at 6,675 square kilometres, plus roughly 300 smaller islands and islets. Together they form an archipelago of 7,215 square kilometres in the sub-Antarctic region. The nearest inhabited territory, Madagascar, lies more than 3,300 kilometres away.
History
The islands form part of the Kerguelen Plateau, a large igneous province mostly submerged beneath the southern Indian Ocean. They are administered by France as part of the French Southern and Antarctic Lands, alongside Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and the Scattered Islands. No indigenous population has ever settled here.
What you see
Grande Terre dominates the archipelago—roughly three-quarters the size of Corsica. The landscape is shaped by relentless geography: a harsh climate with frequent high winds year-round, rough surrounding seas that remain ice-free, and an environment of pronounced isolation and desolation.
Cultural significance
The Kerguelen Islands represent one of humanity’s most extreme outposts. France maintains a permanent presence of 45 to 100 soldiers, scientists, engineers, and researchers who conduct work in this remarkable environment. The islands stand as a symbol of remote scientific endeavour and geopolitical presence in the Southern Ocean.
