In reply to SWclimber:
Crag Climbs in Chamonix or Climbs in the Aiguilles Rouges by Piola - but expensive for a single day. There are various topos on line and you may be able to do some photocopying of routes in the Guides Office near the town centre.
Popular valley crags like Les Gaillands will often have people with guidebooks you can ask to borrow if it's only for a day.
