110 km
The day started with a relatively flat route, but a lot of up and downs of about 120 m height difference followed. In Santoña I had to use a small ferry again. It is not always easy fie cyclists to go on board or to leave the small ship. The destination was a beach with soft sand. The ferryman helped to get the bike over the plank to the beach and thn I had to move the bicycle some 100 m to a timbered pathway. Then a long cycle path along the Playa de el Salvé. The beach was fine, but the buildings near it were ugly apartment houses. In the city of Laredo the track inclined and I had a good view over the bay with the ugly buildings.
The next interesting town was Castro Urdiales with a big church near the harbor..
Some kilometers further the track was directly at the coast on a path that remained on RH same height. A local cyclist warned me in Spanish for stairs. I would have to choose another route. I asked him if the stairs go down or up. As he said down I took the risk.I continued this path and enjoyed the views to the ocean and the rocky coast. The stairs wire nit heavy to master in my direction: I just dismounted and used the brakes to get down step by step. In Zierbiena I had started the route to the next camping. I should have waited until the end of the track in Bilbao. Now my Garmin routed me to the harbour area and I was stopped by security people. They told me, I had to return for ad one kilometers and choose another way.
So I did and used the right road to Portugalete. There I crossed the river by means of an hanging ferry, the Puente Colgantede Bizkaia.
Now the track I followed ended and I routed again tot he target camping that I reached without high efforts.
The rest until Hendaye I have to route myself.

The camping was not quiet all night long people were walking, speaking and cleaning the toilets with hoses.
There were also a number of steep ascends that cost time.
Highlight of today was Santillana de la Mar a pilgrims town with a lot more tourists than pilgrims.
In the large town Santander I did not see much interesting buildings on my track. The most well known was the building of the Bank of Santander near the quai for the pedestrians and cyclists ferry to Somo.
From the ferry I had a view to a royal palace on a peninsula. In Somp I went to a camping, because the next camping would be too far (risk of steep hills).

From the heights there was a view to the coastline and some bays. I could see the humidity from the ocean drifting to the mountains.
Before crossing the Rio Sella to Ribadesella  detected some shipwrecks in the bed of the river. In the town some shops were opened on Sunday and I bought a fresh bread for my lunch later in Nueva. I saw many people in the restaurants and siderias, maybe to celebrate the special weekend of  Maria Ascension. After Niembru I was ay the sea level again. A church was built in a little peninsula in a small bay.
Llames was marked wit a star on my map and it had an old center. There was a festival going on and many people were dressed in local costumes. On the Pjlaza Parres Sobrino a folkloric group showed a dance and a lot of people were watching it.
After the crossing of the Rio Purón the cycle track came through a slowly ascending deep valley of Eucalyptus forest. It was like a part  of a jungle and there could be a group of monkeys in then next tree. As the valley ended I biked through an environment  like the Austrian Alps. Cows mowed and some had bells.
In Pesués I choose the quiet route national instead of the track, because I did not want to risk a steep part at the end of the day. It was the right decision, because I had a splendid view to San Vicente with a large church and a castle
