In reply to mmmhumous:
Thanks all was picking folks brains over the weekend on a winter climbing course, and have settled on Garmisch-Partenkirchen.
We're going do the Zugspitze/Aplpspitze tour (up past the Hollentalanger Hut,spend the night at the Munich House then take the Jubiläumsgrat to Alpspitze and descend by the Alpspitze via ferrata and then cable car). After/before that (if folk have the energy, we'll do a bit of bouldering/sport climbing/tobogoning/spa-ing (the wet type not the MT type).
Will definately consider some of the options on here for next year (never even looked at going to the Ecrin area before).
