An extraordinary journey
A crossing of Corsica from north to south
The GR20 runs from the North to the South of Corsica , linking Calenzana to Conca . It is traditionally divided into two distinct parts:
- The northern part , the most technical and mountainous, where the cliff-side passages and steep climbs offer breathtaking panoramas.
- The southern part , a little less rugged, offers more rolling terrain, although still demanding, with plateaus, valleys and dense forests.
The GR20 crosses mountainous regions of exceptional beauty, including the Aiguilles de Bavella and Monte Cinto , the highest point in Corsica at 2,706 metres . This unique route is a true immersion in the wild nature of the island.
Technical and challenging stages
The GR20 is divided into 16 stages that vary in difficulty and duration. Some sections of the trail are extremely technical, with steep passages requiring great concentration and sometimes the use of ropes or ladders. The altitude, changing weather conditions, and rocky terrain increase the difficulty. This trail does not forgive mistakes and requires rigorous physical preparation.
