I've done the 3 Conseillers ridge over 20 times. My favorite for an introduction to Alpinism when I was leading for my local French Alpine Club group. Note the spelling It's short and not very difficult ( I've soloed it 3 times) but good solid granite and the summit has one of the best views in the Pyrénées. If you're fast, you can couple it with the Ferbos ridge on the Pic 3 Conseillers, which is much longer but no more difficult.
You mentioned yourself the Salenques- Tempestades. It's a very long day, I usually do it with a bivouac for 2 nights at the lake below the Col de Salenques. Nice having the summit of Aneto to yourself in the late afternoon and knowing that there are a few beers chilling in the lake !
Another favorite of mine is the 'Piton von Martin' route on the Pic Palas. At just under the magic 3000m, the view from the summit IS in MHO the finest in the whole range. Most of the difficulties are concentrated on the Piton ( IV). Descend by the Geodesiens ridge. A night at the Arremoulit hut is always a pleasure. I usually bivvy by the lake but have a meal in the hut. The food is good !
If you're in the Ossau valley you might as well go and do a long route on the Pic de Midi ! There are so many to choose from, I wouldn't know where to start ! Something a bit out of the ordinary would be the West Face of the Petit Pic and traversing to the Grand Pic . Again a long day, difficulty D. There is one memorable 'step' when there are hundreds of metres of 'vide' under your feet on the North Face of the Petit Pic !
Lastly, how about the North Face of the Vignemale ? It's 850m of easy climbing, but 850m ! It's amazing the number of people who aren't fast enough and spend the night on the route ! Just the once, I did the Direct Sortie to the summit. This involves a little (V) and believe me, when you get that far you are already truly knackered! The Oulettes hut is too big and busy for my taste but there are some great places to pitch a tent nearby. Again it's great to spend 2 nights there and enjoying a great feeling of satisfaction waking up on the second morning, seeing what you accomplished !
Want to know anything else-just ask !
