Hello All,
I’m considering taking 10-14 days to hike the GR20 in mid-October 2023 and have a few questions pertinent to doing the trek in the offseason.
From the info I’ve gathered, all the refuges and gites will be closed for the season so I’ll need to be self-supported. I’d prefer not to carry all the food for the entire trip, so I’m wondering what are my re-supply options on the trail. One blog I read mentions being able to “supplement your supplies at Asco Stagu, Castel di Verghio, Bavella and do a full resupply at Vizzavona.” However, aside from Vizzavona, the above locations appear to pretty small with minimal services.
Can anyone provide some information on where I could potentially re-supply along the route and what kind of food supplies might be available? I plan to bring some freeze-dried meals, dried foot, bars, etc. from the U.S. The quantity of the latter will depend on food availability en-route, but it would be nice supplement with some local sausages, cheeses, and bread regardless. If resupply en-route is not an option, then I may follow a suggestion from this forum and rent a car and attempt to stock my own re-supply caches, so that is an option.
Also, despite the refuges being closed, my intention is to sleep in their bunkhouses, which I understand remain open throughout the year. I plan on carrying a sleeping bag and pad (and a bivy or tarp just in case). In addition to using the bunkhouse, I’m hoping to use the common cooking facilities at the refuge. Does anyone know if these facilities remain open and useable? If so, what is provided? If the cooking facilities aren’t serviceable or reliable during the offseason, what are my options for obtaining camp fuel in the larger towns (e.g., Calvi)?
I’ve read that public transport in the offseason is unreliable. Will there be any difficulty reaching/leaving Calenzana or Conca?
Finally, I’ve checked the satellite imagery for the last five years, which indicates snow cover should not be much of an issue until November, but if anyone has personal experience that differs from this I would appreciate hearing that.
Thanks,
Brand
