Route
The GR20 consists of two parts:
1. The northern part starts in Callenzana and ends in Vizzavona. It covers the roughest terrain, due to the steep and rocky paths, but it is the most scenic part.
2. The southern part from Vizzavona to Conca is “easier” and less spectacular. The Coscione plateau and its green meadows is one of the highlights.

The GR20 crosses Corsica diagonally from the north to the south. Its length is approximately 170 km and it can be walked in 15 days. It involves ascending a total of 11,000 metres, though climbing skills are not required. Nevertheless, a perfect physical condition and some hiking experience are necessary to cope with the rough terrain. The number 20 in GR20 stems from the time when the island was assigned this department number by the French government. Today, Corsica is divided into two departments, namely Haute Corse (2b) and Corse-du-Sud (2a).
