North → south or south → north?
The vast majority of hikers walk from Calenzana to Conca: it is the direction used in guidebooks and in the official stages. Walking the other way lets you start with the south, which is slightly less technical, and meet groups instead of following them. The Park publishes stage times in both directions.
The full GR20 or just one half?
The GR20 splits naturally at Vizzavona, served by the Ajaccio – Bastia train. Walking just one half is an excellent way to discover the trail in a week. See our north or south comparison.
