More widely known as Tristan, Tristan da Cunha is one of several beautiful volcanic islands in the south Atlantic ocean. They're famous for their remoteness. In fact, as of 2014, Tristan only had a population of 297, and it doesn't even have a runway to facilitate air transport. The only way to get to this island is by boat, which reportedly takes as long as six days from South Africa!
Tristan da Cunha is said to be the most remote archipelago in the world - so, needless to say, if you're looking to get away from it all, this is the place to be!
