Camino del Norte
12.9 km, 141 m up and 191 m down, through 1 place. Where you stop is up to you.
Every place on the path in order, with the distance from Portugalete. Most are too small to sleep in — a fountain, a chapel, a bar that may or may not be open — but they are what the day is actually made of.
The route from Portugalete to La Arena is almost entirely on paved surfaces, and getting out of the expanses of the city require twisting and turning your way around and under the complex network of highways that crowd out green space. Much of the trail is along a dedicated bike path, separated from the highway by a tall glass divider and decorated with the silhouettes of birds. This bike path is part of a larger network of paths that connect many of the suburbs, so pay close attention at every junction. See notice below for possible confusion near La Arena.
The camino follows the boardwalk in La Arena, where it eventually joins a new foot bridge over the small estuary and into Pobeña. After crossing the bridge you have the option of going across the parking lot to the town, where you will find the albergue and several restaurants.
Just prior to arriving in La Arena, you may notice old arrows directing you to your left. They occur shortly before passing under a bridge and should be ignored. Continue straight into La Arena.
To keep on the camino, do not cross the parking lot. Instead look to your right; just past the Residencia Pobeña is a narrow path that takes you uphill for a beautiful walk along the headlands.The camino turns inland and passes under the A-8 just before arriving into Ontón, and along the way you cross into Cantabria.
Distance, climb and descent are measured along the GPS track for this camino — 237 recorded points across this span, the same track the app carries. The town-to-town figures in my data put it at 12.1 km.
