Join us on an unforgettable GR20 trail running adventure in Corsica! 

The GR20 is one of the top trails in the world. It spans 180 km (112 mi) and crosses the stunning island of Corsica from north to south, as well as attracting many adventurous spirits that explore it either hiking or running.

Crossing the GR20 is no easy feat and requires proper training and guidance. On this 7-day challenge, we will have the chance to enjoy trail running on this world-famous route, which many consider Europe’s most difficult. You will receive a personal assessment, professional guiding during the tour, luggage transport, and more. You can find a detailed itinerary below.

Keep in mind that tackling the GR20 requires a very good fitness level. The terrain is rough and it is an up and down trail through the mountains. Therefore, you should not underestimate it and should prepare for the adventure adequately. Of course, we will be there every step of the way to help and guide you.

Le GR20 du Sud a été superbe et je suis revenu avec beaucoup de souvenirs grandioses. Je suis très heureux de mon séjour, de cette première approche du GR20 et de la découverte de la Corse « qui se mérite ». Je remercie Couleur Corse pour leur organisation et leur efficacité qui nous permettent de marcher sur un chemin mythique le GR20.

The GR20 (Sud + Nord) hike was stunning. Well organised (the stays at the refuges/bergeries and the food) and both guides (Paul for Sud and Julien for Nord) were excellent. It is not the easiest of hikes yet very fulfilling.

Super expérience avec un guide excellent (Serge). Expérience physique doublée d'une très belle expérience humaine.

I applied for an english speaking group. At least thats what i thought so it was a great surprise when i found myself as the only one in a french speaking group who did not understand a word whats going on. I bought a package, for my limited nimber of vacation days, where i wanted to enjoy myself, part of the package should be networking with other people in the group. Otherwise i would have gone into the Alps hiking myself, that is where i live. Also my dietary requirement was ignored. As a vegan i had a hard time trying to find dishes i can eat without ending up in a medical condition. Also it would have been nice to get a detailed description about the accomodations. It was a great surprise finding out i have to pay 40 euros extra to have a standard european level accomodation. Fortunately the guide managed to turn this initially very negative experience into a better one.
