In reply to Alex_Handhold:
Your profile suggests you have mostly top roped single pitch climbs and soloed some Mods and Diffs. Have you climbed any snow / do you have the equipment for snow? So whilst all the climbing routes mentioned above are great I cannot recommend them for you. The Crochues Traverse has only a short section of climbing around Diff / V. Diff but lots of extremely exposed scrambling ground and depending on when you go may have snow in some sections.
Alternatives could include:
-Le Buet, a lovely 3096 metre easy peak
-Take the train to Montenvers and descend the ladders ( can use via ferrata kit if not comfortable soloing them ) and then explore the dry Mer de Glace glacier.
- Le Belvedere has only a very short section of climbing around Mod / Diff ( likely to be some snow on the approach )
- Do the Crochues in reverse, starting from the col de Dards, and turn around when required ( likely to be some snow )
- Walk up to the spectacular Albert Premier hut and explore the ground behind the hut ( snow patches at the start of the season )
- Take the lift to the Brevent and do some of the spectacular little scrambles along the ridge heading towards the Index ( snow patches early in the season )
