The 16 Stages of the GR20 — Distances, Climb & Times
The GR20 across Corsica is classically walked in 16 stages over 177.5 km, from Calenzana in the north to Conca in the south. The northern half (Calenzana → Vizzavona, ~92.5 km) is the rockier, more technical part of the trail; the southern half is greener and slightly gentler. Below you find every stage with distance, ascent, descent and a realistic walking time. The RandoNav planner can re-split these stages into any number of days to match your own pace.
