After Tarrueza the camino crosses back over the A-8 and at a large roundabout junction with the N-634 it leaves the busy road for a side road uphill. There is only one clear way across this large roundabout, to your right, and the road uphill is the first obvious choice. The road takes you towards an unsightly tower. Immediately after it turns left downhill to cross directly over the N-634 to a set of stairs. These stairs descend through the Puerta de San Lorenzo directly into the old town of Laredo.
