The D119 from Mont Louis to Axat is a great road too.
The C roads going east from Tremp across to Berga are superb too (C1412, L511, L401, LV4241), if the weather is good and you like your roads twisty
We're heading over this area in late June.
Another vote for Jaca here, although I have some bad memories of a late night bar that we were later told was a nockin shop :|
