The 16 official GR20 stages
From Calenzana to Conca, the GR20's official split runs to 16 stages, refuge to refuge. Distance, elevation, difficulty, walking time and GPX tracks — to set your own pace, whether you follow all 16 days or group some stages together.
Understand
How to read this split
This 16-stage split follows the route's PNRC refuges (plus Vizzavona, E Capannelle, A Matalza and Conca, off the refuge network) — the most common pace among hikers doing one night per stage. The figures come from the same OpenStreetMap track as the rest of the site (182.4 km in total): they can differ by a few metres from the total shown elsewhere on the site (segment-by-segment calculation method, normal variance <1%%). Each stage has its own page: distance, elevation, difficulty, estimated walking time, and GPX tracks to download in both directions.
