The section between Linares and La Hermida will be a great surprise. It is a winding mountain road that will leave you with tired legs and a feeling of joy at being able to enjoy such unparalleled views. On the way down, I suggest you visit the Romanesque church of Santa Juliana, right at the entrance to the town of Lafuente.
