In reply to shaun walby: I would 2nd or 3rd... the Aig Moine, if your happy at E1 as you're profile says you'll be fine up and down the easy route. You can do it without a rope, or take a rope so when almost at the bottom you can ab off slightly early down onto the snow, in case there is rimaye where most people congregate before heading off on the 2 main route choices. Courvecle Hut is good too, great views of the Jorasses, or walk up around the corner to see more of the Verte. You can follow part of the balcony to get to the hut, or just head up the glacier (dry) and do the ladders
Northside of valley get the La Flegere tele(La Praz), then walk up the hills behind the Index (limited old snow), follow the ridge and little peaks as far as you like before dropping back into Chamonix itself. Some good scrambling to be had along the way.
