Thank goodness the legs are still okay, as it is obvious that the memory has gone! After Oloron on my way to Somport I remember Sarrance, I remember Borse, but no Accous! As for the width of the road I spent 6th April 2008 walking from Sarrance to Somport via the road. I did not think it especially narrow, and I never felt in danger from traffic. It is also not especially steep, or I would not have been able to manage 4o km, mostly uphill. It was still ski season at Somport, and I was lucky to get a bed for the night.
