In reply to sheelba:
Visited French Pyrenees several times by self and with friend over 35-45 years ago.
Then used the Guides Ollivier which comprehensively covered walking and climbing and which could easiest be bought in eg local newspaper/book shops. you could probably ask the various UK 2nd hand mountaineering bookshops if they have guides. Bellefon's Les Pyrenees 1976 covered best routes of all grades grades(coffee table book in French). Battagel's and a Cicerone easy route guides were also useful. There are probably many more recent books. There have been at least 2 English selected climb books.
Can't remember names or peaks much. Some classic routes in the Cirque de Gavarnie were the Voie normale (lower tier) and Grand Diedre (2nd tier). Also ridge of Astazou (prob all AD) can continue round upper Cirque to Breche de Roland inc Marbore, Cylindre. Main face of Pique Longue on Vignemale (D) 800m, Arete de Gaube (AD). Routes all grades on Pic du Midi d'Ossau (granite) to W inc traverse of all peaks. Cirque de Troumouse, long ridge prob PD/AD. PD varied route on Mt Perdu from Ref de Tuquerouye. Did various easier routes to E of Gavarnie inc one on Spijeoles (all good).
Only once used crampons on approaches (R Tuqu) in summer though an axe was often invaluable (but went later than June...however glaciers may have receded. Remember pegs (usually in place) were invaluable on the limestone above AD...I find that a large stone is usually sufficient to place a peg but not to remove one (could take one tool with a pick and hammer head rather than an adze?) .
I walked back down to Bagneres from a hut in the Pic des Spijeoles area but it was a long day. There are quite a lot of unwardened shelters inc shepherd's huts in the Pyrenees (Ref Tuquerouye was an unwardened ref) and would suggest bivi bags etc rather than tents as weather often good in summer.
Look on internet...there were eg buses to Gavarnie and Cauterets from Lourdes.
I do have several old French guidebooks but hope to use them myself one day....let me now if you really can't find anything nearer your trip.
