The World's Most Isolated Islands, Where Residents Rely on 'Supply Ships a Few Times a Year' to Buy Goods

Located in the South Atlantic Ocean, the Tristan da Cunha archipelago is the volcanic island group furthest from any continental mainland inhabited by humans: It's a staggering 2,800 kilometers from the nearest continent, South Africa. The island has only about 250 permanent residents and absolutely no airport! For residents to leave the island or receive external supplies, they depend entirely on Antarctic research or fishing vessels that sail from South Africa only 8 to 9 times a year. If they miss a ship, they're stuck waiting on the island for another two to three months.
