The life of Castro Urdiales still revolves around the Puebla Vieja, or old village. It is here that you can explore the most impressive and oldest monuments.
Make your way down to the harbor (a short distance from the camino) to visit Iglesia de Santa Maria perched up high. Nearby is the Faro y Castillo de Santa Ana, the Medieval Puente Romano, and the Ermita Santa Ana. When you are done exploring hustle back to the Plaza Del Ayuntamiento for a fill-up.

Castro Urdiales was settled first by the Romans, who used the location more for its iron than the sea. It prospered under the reign of the Kingdom of Castile right up until 1813 when the French Army destroyed the city. It was quickly rebuilt and fortified.
The camino through Castro Urdiales follows the N-634 but it is possible to walk the coastline, a route which is a great deal more scenic. It can be followed as far as the beach at which point you will need to turn back towards the main road. A short distance later the camino turns left towards the Plaza de Toros; the municipal albergue is located at this end of town behind the bull ring.
After passing the Plaza de Toros (on your right) the camino arrives at a tunnel under the A-8; large signs for CAMPING let you know that you are on the right track. Eventually, you will pass the camping, and a short distance afterward, Allendelagua.
