Old Military Garrison Ruins with View of Castro Urdiales Bay

Highlight • Historical Site

We went off the camino today, wanting a coastal walk and enjoyed the various stopping points we found overlooking the busy port. The next stretch towards Pobeña became quite steep in parts, especially downhill when the dust became slippy. Take care! There are caves along the top and old military garrisons, including a canon.

View from Mirador de San Juan (Monte Serantes)

Highlight • Viewpoint

Serantes is a very beautiful and easily accessible mountain, the view is great when the air is clear (on one side the Spanish countryside and on the other side the port of Bilbao + Atlantic coast). However, some paths are a bit overgrown, so watch out for ticks and snakes!

El Mazo Ruins

Highlight • Historical Site

Old ruins in the middle of a freely accessible cow pasture, which now shelter the cows. If you are not afraid of cows, you can also visit the ruins from inside.
