Antarctica
Antarctica is a continent, not a country. This frozen place a little smaller than 2x Australia has mountains, deserts and a whole lot of snow and ice. Different countries claim parts of it, but very few people live there. The only real inhabitants are penguins.

You can reach Antarctica by ship from Tierra del Fuego, Argentina.
