Valfrejus has lots of ski touring nearby. So far I’ve only done Pointe des Sarrasins last March. I read about it in the Olizane guidebook (in French) for ski randonnee Savoie.
I was not staying or skiing at Valfrejus, just drove up one morning, parked and starting heading up the GR 5. After about half an hour of quietness, I discovered that in winter it is actively used as a ski piste. (So if you have a week lift pass at Valfrejus, might save you some time getting to some tours).
My guess is the main problem you’re having in finding info is that ski touring desciptions and reports are typically indexed by the name of the summit and aspect—and you don’t yet know which summits are in which of these categories: (a) peaks in the same region, but not reachable by Valfrejus as a daytrip; (b) peaks near Valfrejus that have a lift to (or near) the top; (c) peaks + ridges within daytrip range which do not have a lift.
So it will help a lot to just order a paper map (or a digital map, like the IGN 1:25000 maps for that region are available on DVD). The ski touring region containing Valfrejus is often Thabor - Cerces - Mt Cenis. My perspective is that I wish I’d done more tours in around there (and in the nearby Haute Maurienne)—and I own the Guide Blanc—but in reality I almost always end up doing some other good tour closer to the population centers. (so finally I gave up on bringing the Guide Blanc with me on the airplane to France—rely on the Olizane guide and usual websites instead).
Next it will help to learn some French. Lots of popular ski stations have English-language guidebooks for skiing off-piste. Valfrejus is not one of those. Maybe that’s why you chose it?
For ski touring, there are now some detailed English-language guidebooks for two regions closest to the Geneva airport. Hint: Valfrejus is nowhere near these regions.
I predict it will be a long time until there’s much info in English about ski touring around Valfrejus. One of the most popular French ski guidebook does not yet even have tours for that area in French.
. (Mt Thabor is a known goal for English-speaking ski tourers, but as a multi-day trip, and that’s in one of the English language guidebooks)
My feeling is that you’ve chosen a good location for less-crowded ski touring, and chosen a good time go there for ski touring. Now you just need to take the next step of getting a map and some guidebooks—and learning to read French.
