Hello
@Coverbid and welcome to the forum. And thanks to
@ivar for moving your question to a prime site!
Do feel free to ask questions and people will be very willing to give replies. You will see a link above to my own experience and advice about crossing the GSB.
Strangely, to answer your specific question, getting lost on the path up to the GSB and down to Aosta is "almost impossible" - in good weather. All the way up and all the way down you are on very well waymarked footpaths. So getting lost is not your problem. In the summer season you will be meeting recreational walkers in that area. And also, despite the fact you are heading to the highest point of the whole journey, the climbing as such, will not be a great problem. It is
relatively gentle on these stages, perhaps more difficult coming down steeply on the Italian side than ascending on the Swiss side.
The important proviso is the weather as you will see in the above-mentioned thread. If you cross between June and September, you should not have (much) problem with snow, and the authorities will be keeping the road open if it were to snow.
BUT
I think there are many other issues you need to bear in mind. The effects of the pandemic on travel and transport and government regulations and the ongoing requirements for social distancing are I think, and again I say paradoxically, much more of an issue. Very small numbers completed the VF last year and at present I think in simple terms recreational travel in France, Switzerland and Italy are still suspended.
I would very much recommend you to refer to the website of the Confraternity of Pilgrims to Rome (CPR), as well. The CPR is
here. There is a large amount of information on this very active site including
this guide to planning. There is in addition a FB
group.
This present subforum is also helpful and will usually elicit a quick and helpful reply.
Wishing you success....eventually. Tim
