GR 20 In 12 days (in august) - my experience
I, my name is Andrea and i'm italian, from Milan.
Due to the large amount of email i received about an old topic i wrote on this forum, i chose to post my experience with gr 20 in 12 days, because i find useless reply to different people with mails on the same object ;)
so i'm copying one of my last reply and i really hope to be helpful.
if you want to do the complete trail, you need 15 days (there are 15 stages) and you have to add a couple of extra days for the trip.
But if you want to do it faster, you can "double" some stages.
I suggest you to study every stage before leaving to Corse, and, by my side, i can tell you my experience:
I walked gr 20 in the standard way, from north (Calenzana) to south (Conca), in the first 12 days of august 2008.
I brought a big backpack (85 litres), with tent and food for 15 days.
I always slept in my tent, except in Haut Asco, at the end of stages 3. In Haut Asco there's a big refuge where you can sleep in different rooms (from 2 to 6 bed, but i'm not sure about it) for 10 euro.
For the rest of the trail i slept in my tent, just placing it near the refuge (about 5 euro for the place... you can't place your tent away from the camping area...it's strictly forbidden).
In august it's very hard to reach below zero temperatures, so i used a sleeping bed for 10 °C. In Pietra Piana (about 2000m), one of the coolest areas where you can sleep, in the night the temperature was about 5 °C.
On the food: i brought some energetic snacks for the day (and energetic powder to make isotonic drink, with minerals and carbohydrates) and in the evening i cooked my own meals with a little gas cooker.
At dinner, I used to eat pre cooked meals like pasta, rice and soup.
If you don't want to bring all the food with you (my backpack was about 25 kg), you can eat at the refuges, at every stages. it's a little expansive (about 25 euro for dinner), but you can go lighter.
Furthermore, i can tell that i was a little fed up with snacks bar, so two or three times i bought fresh cheese and bread at the refuges, in order to carry with me a little fresh food for lunch.
But in the 80% of the time, i ate my own food.
Water: it's hard to find during the trail, so i suggest you to load your bottles (i used a waterbag, it's more confortable) at the refuge in the morning. I started with 3,5 litres every morning (in august it's very hot and you need to drink a lot), and every refuge you met on the way has drinkable water.
I walked gr 20 in 12 days, so i doubled 6 stages as they were 3.
I doubled the following stages:
_ #8 + #9, PIETRA PIANA - refuge de l'onda - VIZZAVONA: from Pietra Piana i walked until "Refuge de L'Onda" (wich is the end of stage 8) and then, after a little rest, i walked until the end of stage 9: Vizzavona (this spot is the one that separate gr 20 north from gr 20 south, there is some restaurant, hotels, place for tents and the train station).
_ #10 + #11, VIZZAVONA - bergeries de capannelle - BOCCA DI VERDI: from Vizzavona i walked until Bergeries de Capannelle (wich is the end of stage 10 ) and then i walked until the end of stage 11: Bocca di Verdi.
_ #14 + #15, REFUGE d'ASINAO - refuge de paliri - CONCA: from Refuge d'Asinao i walked until Refuge de Paliri (wich is the end of stage 14) and then, after a little rest, i walked until the end of stage 15 (wich is the end of gr20 too): Conca.
For doubling up the stages i chose easy parts, where you have to walk a lot of Km but your knees can rest because theese parts are not to heavy (they're a little smoother then other, so you have to walk for a lot of hours but the vertical meters are not too much, so don't get too "up and and down").
Every doubled stage took at least 8-9 hours walking, and in the last one i walked about 10 hours.
That's all, if there's something not clear, just write here and i will be pleased to answer.
Andrea.

Hello Andrea, thanks for your report (by the way, I'm Italian too :) )
Some friends and myself are planning to walk the northern section of the GR20 (Calenzana-Vizzavona) starting probably either June 26 or July 3 (yet to be confirmed). I have some questions if you don't mind.
Is the booking system absolutely mandatory for either tents and refuge?
Is there a campsite in Calenzana where to set up our tents the night before we start?
Are there any guarded parking lots/garages in Calenzana where to leave the car?
We also want to carry our own food. Can we buy food supplies at every refuge or do we have to carry for 3-4 days? In this case in what locations can we positively buy food? (this is very important because - as you experienced - food weight is critical).
Thanks for your help

Andrea will not be able to respond to your query reference booking . She walked in 2008 before it was implemented. Is it mandatory? The system is untried so no one knows. Last year it was mandatory but ignored !
Yes there is a place to camp in Calenzana - next to the gite.
I don't understand your food query. If you want to carry food there is no need for food supplies at all locations. Food is available at all locations but may be limited in quantity and type.

Pedro,
Thanks for your reply. Sorry I didn't answer sooner.
I will be arriving on the island Sat 3 at 22.30 in Bastia with 2 other friends.
We would like to camp in Calenzana but we don't know if we find the reception open so late. Do you know where I could find such information? I tried sending an email to the Calenzana gite d'etape communal email address but they never replied :(
We also would like to leave the car in a guarded parking place.
Finally the food question. I was asking if we could buy food supplies at all locations because we wish to carry as little as possible.
Thanks for your kindness.
Michele

Hi michele!!
as Pedro said, i don't know about the refuges reservation, but it's seems to be not mandatory because nobody use it!
in my opinion, if you go with your tent, there will be no problem for sleeping near the refuges.
for the Calenzana reception closing time i can't help you...we arrived at 20 o'clock and so we had no problems!
about leaving the car in guarded parking place, we have the same problem...i'm planning to do a small part of the trail (5 stages in the middle) and after walking we want to tour the island with our cars...but we don't know where leave the car!
about the food: every refuge has food (cooked and fore sale) that you can buy, from fresh food (bread, cheese, wine) to non-fresh food as can food and pre-cooked meals, but my suggestion is to bring something with you like precooked pasta and energetic snacks to eat during the day ;)
p.s. if you need more infos you can mail me at beach82@tiscali.it (e poi possiamo anche parlare in italiano :D)

We just got back from the GR20 northern half (13-24 June).
Dinner at the refuge can be bought ~EUR15-18 - usually consisting of a hot meal (lentils, pasta, sausage) & a dessert (fresh fruit, preserve fruit or cake).
The exception was Refuge de Carrozzu which included soup as a starter!
Breakfast ~EUR7 (bread, jam, butter, juice and hot drink of choice)
Sandwiches (with cheese, sausage or both) ~EUR7
You should book your dinner/breakfast as soon as you arrive with the guardian.
