The GR20 Corsica Traverse is one of France's great hiking classics. This 167.4 km route connects Calenzana to Conca in 8 to 12 days, crossing the mountainous heart of South Corsica. With a cumulative elevation gain of 10,072 meters and a maximum altitude of 2,383 meters, this trek offers complete immersion in Corsica's most varied landscapes: rocky peaks, dense forests, alpine lakes, dizzying cliffs, and natural caves. Hikers discover contrasting panoramas, from exposed ridges to forested valleys, passing through traditional mountain huts. The GR20 remains accessible without a car: the starting point at Calenzana is served by ferry, train, and flights to Calvi, followed by a 30-minute bus ride. Upon arrival at Conca, a shuttle to Porto-Vecchio allows connection to public transport toward Figari or Ajaccio. Note: seasonal transport services require advance planning.
