Q & A

  • What would you have changed?

    The weather because the rain was making the hikes very dificult ! Except that, everything was incredible : the landscape, the peaople I've met, the atmosphere of the mountains, the kindness of huts' caretakers...

  • Anything go wrong during the trip?

    No :)

  • How was the food?

    I didn't stayed at Petra Piana's hut but I took a very goog lunch over there. The restaurant owners are very sweet !

  • What tips would you give a friend?

    Carry your own food in your backpack for this hike because as all the huts were very remoted and the food was very expensive ! To restock, you will find a little food store in the Vizzavona camping.

  • Packing tips?

    Sunscrean, rain poncho, bring reusable water bottles that can carry at least 3 liters.

  • Transportation Tips?

    If you are in France before, take a ferry boat instead of the plane :)

  • Booking details?

    Here is the official website where you can book your nights in the huts. If you want to camp next to the hut, it's possible and it's cheaper :) You can either camp with your own tent (7€) or rent one directly on site. https://pnr-resa.corsica/
