I agree-- this is the part of the Camino where ankle-height boots are a blessing from heaven. I saw people on hiking sandals on that stretch that had to go really, really careful because even if stepping right, the stones and incline were very tricky to maneuver without exerting higher stress on hips and knees.
@gerardcarey : the road eh?
Well you better be prepared to be looking over your shoulder for the cars coming down and trucks coming up. You just need to take it slow and steady particularly if its wet.
@gerardcarey - The first time I took the trail all the way to Molinaseca it literally kicked my butt. It was a dry day too. So the last two times, after reaching Acebo, I have walked on the road facing traffic. Fortunately traffic was very light and I never felt like I was in any danger.
