CORSICA
CHALLENGE 9
WALK THE SPINE OF CORSICA
WHAT YOU'LL DO IN THIS CHALLENGE
Trek 180km along the mountainous spine of Corsica on one of Europe’s most demanding long-distance trails. The GR20 takes you from the island’s northern highlands to its southern forests across knife-edge ridgelines, alpine lakes, and remote mountain passes. It’s a bold crossing that has over 11,000m of elevation over the route.
You begin by meeting your experienced guide at the first gîte where you will receive a brief on the route and prepare your equipment for the route. This is more than just packing right; it’s about stepping off on the challenge with confidence, clarity, and the right mindset. The next day, you start with a baptism of fire, with 1,360m of elevation gain over the first 11km. This is the first sign that this is not a guided stroll.
Over the following 12 days, the route climbs and drops relentlessly, with a total elevation gain that surpasses the height of Everest. You will link high refuges with exposed paths, boulder fields, and steep ascents. From Monte Cito to the Forest of Vizzavona, every section of the route is a new story and asks something different of you. On the trail, nights are spent in mountain dormitories or tents.
