The questions we get asked.

How many kilometers long is the GR20?
According to our calculation based on the waymarked route mapped in OpenStreetMap, the main route is about 184 km long from Calenzana to Conca, with about 11,100 m of ascent. Published sources give between 177 and 185 km depending on the variants taken.
How many days does the GR20 take?
The Park's official itinerary has 16 stages. Most hikers complete it in 15 or 16 days; the fittest in 12 or 13 days, and fastpacking trail runners in 7 to 9 days. Many only do one half: the north (Calenzana – Vizzavona) in 6 to 10 days, or the south (Vizzavona – Conca) in 5 to 8 days. See our itineraries.
What is the highest point of the GR20?
The Pointe des Éboulis (2,607 m), on the Haut-Asco – Tighjettu stage, since the route no longer goes through the Cirque de la Solitude. Monte Cinto (2,706 m), the highest summit in Corsica, can be climbed as a return trip from this point.
Do you need to book the GR20 huts?
Yes: booking is compulsory for every night, including bivouacs, on the Park's platform (pnr-resa.corsica). Each hut has a nightly quota. Details in our booking guide.
When do GR20 bookings open for 2027?
The 2027 date had not been announced as of November 2026. In 2026, the platform opened on January 20 (January 15 in 2024): bookings will probably open in January 2027. The Ortu di u Piobbu, Carrozzu and Usciolu huts are the first to fill up.
How much does a night in a GR20 hut cost?
In 2026: €20 in a dormitory, €12 to bivouac in your own tent and €27–39 in a rental tent. Allow about €20 for dinner and €10 for breakfast. See the budget guide.
