In reply to Jeromecooper:
Years ago had a couple of weeks in Gavarnie in march. Did Monte Perdido and the traverse of the top of the cirque from the Sarradets Hut, plus the Taillon and nearby tops. Also the traverse of the Vignemale from a bivvy. All these were superb. Then a big storm dumped loads of new snow and put things out of commission for a couple of days. Finished by wading up to a bivvy hut above Gedre and doing the Maou and Lentilla Aretes and Pic de Campbieil. All PD/AD, so lots of Scottish I/II, with a few bits that might be III (top of the Maou Arete for a start, scary loose wall). Sometimes hard work approaching the routes in deep snow, but good neve high up and about thirty 3000m summits over the 2 weeks. Brilliant trip. (and there's always the big ice routes, of course, and the Couloir de Gaube on the Vignemale).
Have fun wherever you go,
Iain
