In reply to s2122:
‘The valley is pretty dark though and Alagna is quite expensive. Don't think there is much camping in Gressoney valley, but haven't been for a while.’
Really surprised to read that Alagna is expensive, it’s certainly not Chamonix expensive or expensive by Italian tourist trap standards.
Theres a free car park in Alagna in which you can leave the car with no issues.
Camping up high is tolerated, using the lift to transport all the gear & food is accepted.
The big issue between Gressoney & Alagna is the drive time & depending if you’ve traveled down the Aosta valley or approaching from the Simplon?
There are campsites lower down the Valsesia valley if the Alagna one is unsuitable.
Feel free to msg me if any more information is required, I’m usually resident in Alagna when not working.
