Thanks for your reply!

I'm not proficient in winter camping, but I've camped about 10 times in winter in the mountains, I have the right gear and know how to use it.

The info I'm looking for is particularly the weather: the temps, the amount of snow, avalanche danger and which treks to choose to avoid it.

If you've camped there in the winter, I'd be interested in which trips you've done, the conditions you encountered, etc.
