The GR20 North

Finally, try the experience of the GR20 North, the most mineral part of the GR20, over 7 days!

Welcome on Saturday at 2pm at Ajaccio airport.
End of the course on Saturday and return to Ajaccio around 9 a.m.

The northern slope of the GR20 promises an unforgettable experience to any experienced hiker, both for the splendor of its landscapes and for the sporting challenge it represents. Indeed, it is the most difficult hiking trail in Europe. This very mineral route will take us in particular to cross, by the highest passes, the massifs of Monte d’Oru, Rotondu, Paglia Orba or Cintu, the highest peaks of Corsica.

Due to its diversity, the GR20 North will also take you through magnificent beech forests, Larici pine forests and on high-altitude plateaus where you can discover the famous pozzines and the no less essential Lake Nino. It is also known for its wild horses in freedom and its exceptional scenery.
