I wonder about the Alps.
True. I was baseing my comments on the suggestion form the original poster that he hasnt got his PPL yet. Moreover as we know it is the PPL with maybe 200 or 300 hours (no other ratings) that are probably the ones that give up most.
I think the French Alps are very doable - but not if this is you. IMHO for most just to much to cope with, particularly in the winter.
I would have thought with maybe a couple of hundred hours experience including some varied flying, time to wait for the "right" weather the Alps are quite possible in just about anything during the better months of the year.
In the winter with a schedule to keep I would have thought it is an IR, a capable airways aircraft which is deiced, probably at least 500 hours experience, and maybe still the possibility of having to add an extra day to your schedule! Unfortunately just not the realistic territory of your average PPPL.
