Church of San Julián de Santullán

Highlight • Religious Site

The church of San Julián is from the beginning of the s. XVI. Several reforms have been carried out, although it keeps its old Gothic layout. Inside we can see in the apse a sculpture by Juan de Garay from the s. XVII. The former presence of an image of Santiago links this church to the Jacobean route.

Old Castro-Urdiales Railway Tunnel

Highlight • Structure

The old railway tunnel that linked Castro-Urdiales and Translaviña was an enormous project in its day.

Today it serves so that you can enjoy a spectacular tour among nature on wheels.

Valverde Tunnel

Highlight (Segment) • Structure

A 400-meter tunnel that connects Mioño with Castro Urdiales, crossing the slopes of the Cueto hill. It is used by both pedestrians and cyclists. From Castro Urdiales to Mioño there is a slight climb, but without problems. Around there is a thick vegetation where ferns and mosses are good indicators of the humidity that surrounds this natural environment.
