In reply to marcusinbristol:
i live in the vallouise valley near the ecrins, about an hour from vars,
there are a few ski resorts that would suit you here, puy st vincent is my local one, just voted cheapest of the resorts in france, (out of the top 20 resorts)
the climbing here is amazing to 85 sports crags in the area and every grade to go at on four or 5 rock types, i moved here for the climbing.
your plan sounds fun, at that time of year i switch between ski touring and craging and love it, the weather is normally nice then, as always when you try and do two activities on the limits of their season you can be disappointed, by weather and conditions, but the last few years your plans would have been easy posable,
if you are staying further south there are a few little french type resorts, and some lower ones near gap, but they may struggle for snow that time of year,
if you like get in touch and i can fill you in on the resorts and maybe climbing here
cheers Rob
