I've got the cicerone book that Ivo linked. It's a great place to start.

There is information but most of it is in French but there are plenty of ascensions to be done in 1 day.

This site has lots of walks on it.

Le Taillon is easy and is a lot of peoples first 3000, but be careful going up to the breche de roland at that time of year it could get cold and crampons MAY be needed to cross the glacier

Summitpost has quite a number of good descriptions.

This is a peak that I particularly enjoyed :

Maybe you knows....(before you buy a map)

 For planning your trips..

There is a on-line map for france

The French IGN maps do exist and can be purchased for memory map at a scale of 1:25 000. I would also advise looking at the 1:50 000 maps from Rando Editions because these have more of the paths and ascensions marked than the IGN version.

The IGN maps often only show waymarked routes, whereas the Rando Rditions which are based on IGN show other routes which exist.

two peaks with great views.
the l'escuzana (gavarnie) is too far from Aramits i think
