In reply to minty1984:
I've spent 3 of the last 4 summers in that area of the Pyrenees and would agree with what's been said above. Ordesa is stunning but get an early shuttle bus as the number of visitors per day is capped, once it's full you can't get in. There is some via ferrata in the valley, it's on a steep walk out of the valley in the direction of the Breche Roland, can't remember what it's called off the top of my head.
The VF mentioned above in the Gavarnie valley is quite short, you can do it in not much more than an hour but it is quite technical as VF go but if you can climb 6a+ it's nothing to worry about, unless you don't like exposed, wobbly suspension bridges.
I think there's another, shorter more technical one still lower down the valley but I'd have to check.
There's probably much more climbing to do at your grade on the French side. This is the book to get

It's in French and Spanish but it's pretty user friendly for non speakers. There's everything from long multi pitch Alpine style rock climbs to single pitch, almost roadside sport cragging with everything in between.
If you're staying in the Gavarnie valley vehicle access to the village itself is restricted, with multiple car parks on the edge of the village, not free but not expensive. The later you arrive the further you have have to park from it. Lots of camper vans overnight there so can keep your space but its not the nicest spot to stay. Further up hill on the road to the Col des Tentes there's another camper van spot but with no facilities (perhaps a toilet waste disposal site?). There are several camp sites strung out down the valley, probably the best is Camping Toy in Luz. It has the facilities you want without being being flash and it's pretty cheap. It's just off the town centre square so all the town's facilities are walkable. Luz has a decent supermarket, banks, gear shops, bars etc without being too big and its very central for getting out in multiple directions.
One thing I've found whilst there is that in general the weather is a lot better than the Alps but there are a lot of cloud inversions. If the forecast for the mountains is good but you seem to be stuck in misty clag, don't be put off. Drive uphill and at some point you'll emerge above the clouds and into the sun.
If the weather in the mountains really is bad, drive downhill (north) until you escape it. The guide book has crags all the way to Lourdes so something should be dry.
If you want any more specific advice, just ask.
