On the GR20, you can no longer set off without a booking. Every refuge run by the Corsica Regional Nature Park (PNRC) has a maximum quota of hikers per night, and booking is compulsory for every option, bivouacking included.
The official platform
All nights in the Park’s refuges are booked through the Park’s booking platform, pnr-resa.corsica, online only and by bank card. There are three options (2026 prices, per person per night):
| Option | 2025 | 2026 |
|---|---|---|
| Sleeping platform in a dormitory | €17 | €20 |
| Bivouac with your own tent | €9 | €12 |
| Rented 2-person tent (1 person) | €22 | €27 |
| Rented 2-person tent (2 people) | €31 | €39 |
Meals cannot be booked online: order them from the hut warden as soon as you arrive, before 6 pm for dinner (around €20 for the evening meal and €10 for breakfast or a packed lunch, according to the Park).
Ortu di u Piobbu and Asinau: in 2026, neither site had a building with a dormitory. You sleep there either in your own tent or in a rented one, and meals are still served.
When do bookings open?
For the 2026 season, the platform opened on 20 January 2026 (15 January in 2024). The 2027 date had not been announced as of November 2026: an opening some time in January 2027 is likely, but not confirmed. The first weeks of June and September are the most sought after, and the refuges at Ortu di u Piobbu, Carrozzu and Usciolu are the first to fill up.
The rules you need to know
- Online bookings must be made at least 48 hours before the night in question.
- Your place is guaranteed until 7 pm; after that, you will be given a bed subject to availability.
- Dates and refuges can be changed online up to 2 days beforehand, subject to availability, but not the option you chose (dormitory ↔ tent).
- On site, the warden cannot change your dates: a night brought forward or put back has to be paid for again at the on-site rate.
Cancellation
- Full refund up to 2 months before the start of your trek.
- For medical reasons: no refund, but a credit note valid the following year (apply with supporting documents at least 10 days beforehand).
- If the prefecture orders a closure (because of a fire, for example), only the days and refuges affected are refunded.
The terms and conditions recommend taking out private cancellation insurance.
Private accommodation
Some stages end away from a Park refuge. Since 2026, the official website has listed their contact details: the Gîte U Fugone at E Capannelle, the Bergerie de Bassetta, the Gîte de Matalza and the Bergerie d’I Croci on the Cuscionu plateau, as well as places to stay at Castel di Vergio and Vizzavona. These are booked directly. You will find them all in our accommodation list.
Our approach
- Choose your itinerary and dates before bookings open, with a plan B a few days either side.
- On opening day, book Ortu di u Piobbu, Carrozzu and Usciolu first.
- Then book the private accommodation, which is not part of the shared quota.
- Keep an offline copy of your confirmations: mobile signal is scarce along the route.
