Overview
The GR20 traverses Corsica from Calenzana in the north to Conca in the south — 180 km through granite ridges, glacial lakes, and maquis scrubland in 15-16 days. It is widely regarded as the most demanding long-distance trail in Europe, with 12,000 m of cumulative ascent and multiple sections requiring chains and fixed ropes on polished granite. The northern section is the most technical; the southern is more Mediterranean in character. Book mountain hut bunks well in advance for July and August dates.
