Vale do Javari, Brazil
One of the most isolated parts of the world, according to Mental Floss, is Vale do Javari in Brazil, possibly because as many as 14 uncontacted Amazon tribes make their home in this region. It comprises an area about the size of Austria – or 86,000 square kilometres. An expedition was mounted by Brazil’s agency for indigenous peoples in March 2019, with the goal of easing tensions between two rival indigenous groups, reports The Guardian.
