CHALLENGE HIGHLIGHTS

This 180-kilometre traverse follows the mountainous backbone of Corsica, a route famous for its knife-edge ridgelines, alpine lakes, and remote high passes. With over 11,000m of elevation gain, the GR20 is a relentless test of stamina and spirit. 

 

The journey begins in the island’s northern highlands, where you meet your guide at the first gîte to receive a brief on the route and prepare your equipment for the expedition. You will pack for the following two weeks so that you can step off on the challenge with confidence 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 just a guided stroll. 

 

Over the following two weeks, 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. 

 

Across 13 demanding days of trekking, you will be boldly crossing one of Europe’s most iconic long-distance trails. An experience that will strip life back to the essentials and leave you with a lasting sense of achievement.

ENQUIRE
  • Is this for me?

    You do not need any alpine experience to take on the GR20, but you do need to be ready. 


    This is a physically and mentally demanding route. You will hike up to 10 hours a day over steep, rocky, and often exposed terrain. The trail is unforgiving in places, with significant elevation gain, rough surfaces, and minimal facilities. Strong fitness and a commitment to preparation are essential.  


    If you’re ready for it, completing the GR20 is something that few forget. It’s a real accomplishment earned with every ascent, descent, and hard-earned view.  

  • How fit do I need to be for Challenge 9?

    This expedition requires a solid base of general fitness and a readiness to spend several hours outdoors each day. You don’t need to be a pro athlete but strong walking stamina is required.


    The fitness plan will assist you in your training.
