Booking the GR20 refuges: a practical guide
On the GR20, bookings are not just an administrative detail: they shape how you split the route, your budget and your ability to change the plan if the weather or your body decide otherwise.
Key points
What matters before you book
Official update 2026: the PNRC states that the PNRC refuges are staffed from 16 May to 4 October 2026 and that overnight stays must be booked, whether you choose a bivouac, a PNRC tent or a bunk. This information can change: always check the official page before paying.
New for 2026: the official platform pnr-resa.corsica opened bookings on 20 January 2026. The most sought-after refuges — Ortu di u Piobbu, Carrozzu, Usciolu — go first: book as soon as your plan is set.
Accommodation
Refuge, tent or bivouac
Bunk
You sleep inside the refuge, where this option exists. It's convenient logistically, but more dependent on the beds available and the communal atmosphere.
PNRC tent
You rent a tent already pitched on site. The PNRC specifies that its tents are designed for two people with mattresses, but you have to carry your own sleeping bag.
Bivouac
You sleep on the designated areas, with your own tent if you have booked this option. Bivouacking outside an authorised area is to be avoided and can pose a real problem for protecting the site.
Good to know
The details that avoid nasty surprises
Your tent counts per person
Even with your own tent, the bivouac pitch is booked per person: for two of you, that means two bivouacs to book, not just one.
Ortu di u Piobbu & Asinau
These two refuges don't offer bunks: only the bivouac or a rented tent. Worth anticipating if you were counting on sleeping indoors.
Meals are ordered on site
The online booking covers the overnight stay, not the meals. Dinner, breakfast and a packed lunch are ordered from the warden — arrive before 6 pm for the evening meal, and carry cash: cards aren’t accepted everywhere at altitude.
Bed held until 7 pm
Your booked overnight stay is held for you until 7 pm. After that, it depends on availability: let the refuge know if you're arriving late.
Get it right
PNRC refuges or private accommodation?
The whole GR20 isn't managed by the Park. Most nights are spent in the PNRC's staffed refuges, booked through the official booking system. But on certain sections, you sleep in private establishments that are booked directly, by phone or on their own website. Mixing up the two means risking finding yourself with no solution on a given stage.
The PNRC refuges
Ortu di u Piobbu, Carrozzu, Tighjettu, Ciottulu di i Mori, Manganu, Petra Piana, L'Onda, Prati, Usciolu, Asinau, Paliri… These staffed refuges are all booked through the Park's official booking system, by date and by location.
Private accommodation
At Vizzavona (hotels and gîtes), at E Capanelle (the U Fugone gîte) or on the Cuscionu plateau (the Bassetta, Matalza and I Croci shepherds' huts), you book directly with the establishment, not via the PNRC.
Why it matters
Work out in advance which nights are PNRC and which are private, depending on how you split the route. You then book each type in the right place, with no nasty surprise once you're on the trail.
The booking system
Booking through the official system
The Park's refuges are booked through the PNRC's online booking system. The booking is made by date and by location, it is in your name, and the confirmation must be shown to the warden on arrival.
A single platform
The Park's GR20 booking system brings together the overnight stays in the refuges: it's the official point of entry for the bunk, the PNRC tent and the bivouac on the designated areas.
By date and by location
Each night corresponds to a specific refuge and a specific date. You build up your sequence of nights stage by stage, in the real order of your progress.
Book early
In high season, beds go fast, especially in July and August. The earlier you book, the more you stay in control of how you split the route instead of having it forced on you.
Official 2026 rates (booking system T&Cs, per person per night): bivouac €12 · dorm bunk €20 · PNRC tent €27 alone or €39 for two (2-person tent, mattresses included). Online payment is by bank card only, and the confirmation e-mail is your receipt to show the warden. Rates are revised every season: the booking system is the reference.
Method
Booking without tripping yourself up
1. Set your direction
North–South and South–North don't give the same sequences, nor the same efforts at the same moment. Start by locking in your direction of travel.
2. Choose your pace
A 12-day split needs fewer nights, but each mistake weighs more heavily. A longer split makes the bookings and the recovery easier.
3. Book by the real date
Each night corresponds to a date and a location. Avoid booking "roughly", thinking you'll easily adjust on site.
4. Keep your confirmations
The PNRC states that the invoice or confirmation must be shown to the warden. Save it offline, with battery and a paper copy if you want to sleep easy.
Margin
What if you change your itinerary?
The classic trap is feeling strong one morning, doubling up a stage, then discovering that the evening's booking doesn't automatically follow. The PNRC states that a booking is in your name, tied to the refuge and date you chose, and that any change must be modified beforehand according to the available conditions.
In practice: if you want to keep the freedom to double up, build your plan in advance with realistic options, not just with optimism.
Change & cancel
The 2026 rules, in black and white
Before paying for a dozen nights in advance, it helps to know what you can change. According to the 2026 terms and conditions of the Park’s booking system:
Changing a night
Changing the date or the refuge stays possible up to 2 days (48 h) before the stage, subject to availability. The type of accommodation (bunk, rented tent, bivouac), however, can’t be changed: you have to make a new booking.
Cancelling & refunds
A full refund is possible up to 2 months before the start of the hike, with no justification needed — date to date: for a 28 July start, cancel by 27 May at the latest. Beyond that, no refund, except for a prefectoral ban (on the days and refuges affected).
If illness or injury strikes
No refund, but a credit valid the following year — request it with proof at least 10 days before departure. Enough not to lose everything to an injury.
Date changes can’t be made on site: everything goes through the booking system, in advance (☎ +33 4 20 06 12 00 or +33 4 95 51 79 06, Mon–Fri 8:30–12:00 / 13:30–17:00 · [email protected]). On site, the warden can only change the accommodation type, subject to space — never the date. One trap to know: a booking whose date has already been changed is no longer refundable. The booking system’s T&Cs are the reference.
