10. Territory of the French Southern and Antarctic islands
These islands in the Indian Ocean are mostly French-owned islands (there's also a narrow strip of Antarctica known as Adelie Land). The Southern Lands consist of two near-polar archipelagos, Crozet and Kerguelen, and two volcanic islands, Amsterdam and Saint-Paul, also in the southern Indian Ocean, that have no permanent inhabitants and are visited for several months at a time only by researchers studying the native fauna.
There are no airports, harbours, or permanent populations; Kerguelen has a small hospital. There's no public accommodation, but the Marion Dufresne, an oceanographic and supply ship, visits them four times a year from Reunion Island, and you can travel on it as a paying passenger. Courtesy: Quora
