The first day of my Camino, I started from Bilbao at 10. Small bike service in the morning and on my way. A nice wide bicycle path leads to Barakaldo, then a very decent gravel road along the highway. The terrain is very undulating and there was no boredom. The country road along the coast is very calm with little …

From the halfway point I only rode on well-developed and wide bike paths with a view of the sea. Shortly before Bilbao I had the opportunity to wash my bike …

The last 15km of the coastal cycle path before Bilbao is really great, Bilbao itself has not …

It goes up and down but it’s very beautiful! The exit from Bilbao by cycle path was incredible in terms of quality and safety for the cyclist! Very nice outing. Some hazards regarding going uphill steps with the loaded bike, I gave up and changed route.
