About this converter
This page compares GR20 Corsica stage distances in kilometers. The GR20 runs about 180 km from Calenzana in the north to Conca in the south across 16 official stages. This list shows the first 12 stages in north to south order, from Calenzana to Ortu through Col de Verde to Usciolu. Short stages like Carrozzu to Haut Asco are about 6 km. Long stages like Ciottulu to Manganu are about 25 km. Time on trail matters more than flat length because climb and rock slow most walkers.
How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Start with a short stage and a long stage to feel the range. Switch the unit row between kilometers and miles to plan maps. Add climb, water stops, and refuge nights when you set a daily plan.
Distances come from GR20 trail stage profiles and refuge to refuge track data. Totals vary from 180 to 189 km by source because GPS method, start points, and detours differ. The Parc Naturel Regional de Corse sets the refuge stages and walk times. Walk times here use 6 km for Haut Asco and 25 km for Manganu as listed in north south profiles. Check current refuge status and weather before you go. Four more stages run on to Conca in the far south.
