Castro Urdiales

A historic fishing port town with a striking Gothic church and medieval castle-lighthouse perched over the harbor. Its atmospheric old town and lively waterfront make it one of Cantabria's most scenic coastal towns.

Things to do

• Iglesia de Santa María de la Asunción — This imposing Gothic church, built in a style echoing Burgos cathedral, sits dramatically on the rocky point above the harbor.
• Castillo-Faro de Santa Ana — Climb this medieval castle turned working lighthouse for sweeping views over the bay and old town rooftops.
• Puente Medieval — Stroll across this graceful stone footbridge linking the old fishing quarter to the town center.
• Walk the Paseo Marítimo — Follow the palm-lined seafront promenade past colorful fishing boats and cafes buzzing with local life.
• Relax at Playa Brazomar — This sheltered urban beach with a natural rock pool is a favorite spot for families and swimmers.
• Explore the Old Town lanes — Wander the narrow medieval streets around Calle Ardigales, lined with old fishermen's houses and tucked-away plazas.
• Visit the Roman ruins of Flaviobriga — See remnants of the Roman port town that once stood here, visible near the harbor area.

Food to try

• Rabas — Castro Urdiales is famous across Spain for this local style of crispy fried squid rings, best enjoyed with a cold beer at a harborside bar.
• Anchoas del Cantábrico — Try the region's prized cured anchovies, salted and packed by hand, often served simply with bread and olive oil.
• Sorropotún (marmite de bonito) — A hearty fishermen's stew of bonito tuna, potatoes, and peppers that reflects the town's deep-rooted fishing traditions.
• Cocido montañés — A warming Cantabrian bean stew with cabbage, chorizo, and morcilla, perfect after a day exploring the coast.
• Sardinas asadas — Grilled sardines served at waterfront chiringuitos are a simple, smoky summer favorite.
• Quesada pasiega — Finish a meal with this traditional Cantabrian cheesecake-like dessert, dense and lightly citrus-scented.

Local customs & good to know

• Attend El Coso Blanco — If visiting in early July, don't miss this beloved night parade of illuminated floats, a major local festival dating back over a century.
• Respect church visiting hours — Santa María church has specific opening times for tourists outside of Mass, so check before planning your visit.
• Expect late dining hours — Like much of Spain, restaurants typically serve dinner from 9pm onward, with tapas bars filling the earlier evening gap.
• Harbor life starts early — For an authentic experience, visit the fish auction area near the port in the early morning when boats return with their catch.
