The hike from SS to Pasaia starts at the base of Mounte Ulia to the east of the city. It begins with a steep climb up lots of steps but the reward at the top is stunning views back across the beaches, city and mountains of SS.
The path is very well sign posted and where there is a junction the correct way is marked with a symbol of red, white and green stripes while the incorrect way has a red and white cross.
Some of the pathway is covered in vegetatian while in other places it is open with views across the Bay of Biscay and the rugged coastline below.
Along the way we passed a 19th century, three story lighthouse which is still inhabitated and has the appearance of a castle perched high on the hill. We also saw remnants of a viaduct which once carried water to the city.
This 7km section is part of the well known Camino de Santiago trail, an ancient pilgrimage route which streches for hundreds of kilometres between France and Santiago de Compostela in the far north west of Spain.
We enjoyed the walk but opted to ride back to SS on the local bus rather than do a circuit!
