The GR20, also known as fra li Monti, is a GR (Grande Randonnée) hiking trail that crosses the Mediterranean island of Corsica and runs roughly from north to south. The whole route is about 180 km long with an altitude difference of 12,000 m. This GR route is considered one of the toughest of all GR routes. Are you ready for it?
Why both ways?You can walk the GR20 in either direction, north to south, or south to north. The most popular route starts in Calenzana, in the north, and ends in Conca, in the south. However, if you want to enjoy a quieter route and encounter fewer people, we recommend starting from the south. It's up to you (or the availability of the huts) which direction you choose.
Camping: during this trek, you can also spend the night at camping sites. Contact our trekking experts to find out more about this option!
