A simple walk through an open landscape. A 500 m. dark tunnel may seem a bit frightening, but it is easy and safe walking. So far, the San Olav shares the path with the Vias Verdes, but at Modubar de Emparedada they separate. Pay close attention to the sign at the crossing: San Olav is down to the right.
After 100 m., there is a working fountain for filling up your water.
