From Isaba turn North and head for the Col de la Pierre Saint-Martin. This is a nice fast as you dare section along the valley floor. It´s not totally open however so it´d be prudent to just cruise it rather than race along it. There´s also a strong crosswind in places which has bent the bushes and trees over so i´m guessing it´s regularly windy here. No traffic to speak of, and a great climb awaits you at the end of this stretch that takes you over the border via a 300 degree right hander. I kid you not :)
