The GR20 is a fun and challenging trek that traverses the island of Corsica from north to south. Often billed as the hardest trek in Europe, it’s an accolade the route probably deserves. Dramatic scenery, rugged paths, airy ridges and steep drops make this one of the most spectacular and varied treks in the world. You’ll need to be fit and have a head for heights. There’s a lot of scrambling, along with a few chains and ladders.
