Full-Day Guided Tour of Bilbao & Castro Urdiales from Santander

Bilbao and Castro Urdiales Day Tour from Santander

Two iconic destinations, one unforgettable day along the Cantabrian coast

This Bilbao and Castro Urdiales day tour from Santander combines a guided walk through Bilbao's storied Old Town with an afternoon in the medieval harbor town of Castro Urdiales, offering two distinct sides of northern Spain in a single, well-paced itinerary. The tour is rated Easy and suits a wide range of travelers looking to explore Basque and Cantabrian culture without the hassle of self-organizing transport.

Bilbao's Old Town, known as the Casco Viejo, rewards slow exploration. A 1.5-hour guided walk introduces the Gothic Cathedral of Santiago, the ornate Teatro Arriaga, the riverside Mercado de la Ribera, and the animated Plaza Nueva, giving context to a neighborhood that has evolved over seven centuries. After the guided segment, nearly four hours of free time allow visitors to step inside the Guggenheim Museum, take a river cruise along the Nervion, or simply settle into a pintxos bar at their own rhythm.

Castro Urdiales offers a quieter counterpoint to Bilbao's urban energy. Its compact medieval center clusters around the dramatic Santa Maria de la Asuncion Church, a Gothic structure perched above the sea, alongside a working lighthouse housed within a historic castle and a stone bridge that has connected the town's maritime and mercantile quarters for centuries. The coastal scenery alone makes the short drive worthwhile.
