Costa Cantábrica Travel Guide: Cantabria's Atlantic Coast and the Gateway to the Picos
Updated: 6 days ago
Most visitors to northern Spain pass through Cantabria on their way between the Basque Country and Asturias. The ones who stop discover one of the most quietly extraordinary coastal regions in the country: wide Atlantic beaches, a medieval village so well-preserved it barely seems real, the oldest known art made by human hands, and the Picos de Europa rising directly from the coastal plain within an hour's drive of the sea.

The Costa Cantábrica runs for about 150 kilometers along the southern shore of the Bay of Biscay, and it belongs to España Verde, Green Spain, in the fullest sense. The hills behind the coast are dense with oak and eucalyptus. The light is Atlantic, clear, and changeable. The beaches are wide and the sand is pale and fine in a way that the rocky northern coast does not always produce.
Cantabria holds 11 Blue Flag certified beaches in 2026, concentrated on the broader sandy beaches around Santander and the eastern coastal towns where the infrastructure meets the demanding Atlantic certification standard.
Most Famous Places
Santander is the regional capital, a graceful port city on a broad bay that has been a summer destination since the Spanish royal family adopted it in the early 20th century. The Magdalena Peninsula, jutting into the bay, holds the summer palace of Alfonso XIII and offers views across the water to the city and the Cantabrian mountains behind it. The city's beaches, particularly El Sardinero, are wide, well-maintained, and significantly less crowded than any Mediterranean equivalent of comparable quality. The old town has good markets, solid restaurants, and a relaxed urban rhythm that feels genuinely unhurried.
Santillana del Mar is one of the most perfectly preserved medieval villages in Spain and genuinely implausible in its completeness. Stone mansions from the 15th and 16th centuries line cobbled streets that have been largely unchanged for centuries. The collegiate church of Santa Juliana contains Romanesque carvings of exceptional quality. The town is a UNESCO World Heritage monument and earns it fully. Go on a weekday morning in the shoulder season to experience it without the day-trip crowds.
Castro Urdiales, at the eastern end of the coast on the border with the Basque Country, is one of the finest medieval port towns in northern Spain. The Gothic church of Santa María de la Asunción rises directly above the harbor and the old quarter below it has been well preserved. The fish restaurants around the harbor are consistently good and the weekend market brings the town alive.
Beaches by Train
The rail connection along the Costa Cantábrica is limited compared to the Basque coast or the Mediterranean, but Santander is well connected to the national network and several coastal towns are reachable from the capital by regional services. Our guide to the best website for train travel in Spain covers all operators and routes.
Santander — direct from Madrid by high-speed train in about 4 hours. From Bilbao by FEVE narrow gauge railway in about 3 hours, one of the most scenic train journeys in northern Spain.
Torrelavega — 30 minutes from Santander by regional train. The largest inland town of Cantabria and a practical base for reaching the Picos de Europa and the cave sites.
Liérganes — about 40 minutes from Santander by Cercanías, a small spa town in the Miera valley with a well-preserved historic center and thermal baths.
For exploring the coastal towns east and west of Santander, a car gives significantly more flexibility than public transport.
Secret Spots by Car
The best of the Costa Cantábrica beyond Santander and Santillana requires a car and rewards every kilometer of the drive. Our guide to driving in Spain covers the A-8 Atlantic motorway along the northern coast, tolls, and the mountain roads that lead into the Picos.
Comillas is a small coastal town about 45 minutes west of Santander that should be far more visited than it is. The Catalan Modernista architect Antoni Gaudí built El Capricho here in 1885, one of his earliest works and one of the most extraordinary small buildings in Spain: an orientalist summer villa with a tower, ceramic tile sunflowers, and decorative detail that makes the building look like it arrived from a different planet. The architect Joan Martorell built a fantastical neo-Gothic palace, the Sobrellano, in the same town. The combination of two of the most significant Catalan architects working simultaneously in a small Cantabrian fishing village is one of those historical accidents that should be better known.
San Vicente de la Barquera is a medieval town on a ria, an inlet, with a 13th-century castle above it and views across the water to the Picos de Europa that are genuinely extraordinary on clear days. The town is small, well-preserved, and has excellent fish restaurants. The bridge across the inlet approaching from the east is one of the most photographed views in Cantabria.
The Liébana Valley and Potes sit in a mountain valley 70 kilometers south of Santander, surrounded by the highest peaks of the Picos de Europa. Potes is a small medieval town in the valley floor with good restaurants and a relaxed mountain atmosphere. The Monastery of Santo Toribio de Liébana above the town claims to hold the largest fragment of the True Cross in existence and is one of the four holy sites in the world granting full indulgence to pilgrims. The orujo liqueur made in the valley from pressed grape skins is the local spirit, produced in small family distilleries and genuinely worth trying.

Hiking
The Picos de Europa, shared between Cantabria, Asturias, and Castilla y León, are among the most dramatic mountains in Spain. The Cares Gorge trail, running for 12 kilometers between sheer limestone walls 1,000 meters above a river, is one of the finest walks in the country. The Fuente Dé cable car rises 753 meters in four minutes to the top of a limestone massif, opening access to high alpine terrain directly above the valley. Routes from the cable car station into the high Picos are well marked and range from short walks to serious full-day routes.
Closer to the coast, the cliffs between San Vicente de la Barquera and the Asturian border offer coastal path walking with Atlantic views. The Parque Natural de Oyambre near Comillas has trails through coastal dune terrain and protected wetland.
Food and the Cantabrian Table
The food of the Costa Cantábrica is built on exceptional dairy, Atlantic seafood, and mountain produce. Cantabria produces some of the finest butter and cheese in Spain, most notably the Quesucos de Liébana from the mountain valley and the fresh cheeses of the coastal farms. The milk from Cantabrian dairy cattle grazing on the green Atlantic hillsides has a richness that shows in the products.
The seafood of Santander port, particularly the fresh anchovies, sardines, and merluza, forms the foundation of the coastal cooking. Anchovies from Santoña, just east of Santander, are considered among the finest in Spain and are exported across the country and to serious restaurants internationally. The process of salting, pressing, and packing them by hand in olive oil is a tradition maintained in family operations in the town.
Sobaos pasiegos, the small buttery sponge cakes from the Pas valley, and quesada pasiega, a fresh cheese tart, are the signature sweet products of the region and sold at every market and bakery along the coast.
Something Unusual to See
The Altamira cave, discovered in 1879, contains paintings produced 36,000 years ago by humans whose artistic sophistication still challenges every assumption about the intelligence and creativity of our distant ancestors. The bison painted on the cave ceiling, in shades of red and black, are not primitive marks. They are sophisticated representations that use the natural contours of the rock as form, produced by people who thought about what they were making and how the firelight would animate it. The original cave is closed to protect the paintings, but the Museo de Altamira contains a full-scale replica that reproduces the experience with extraordinary fidelity. The replica is not a consolation prize. It is one of the most moving experiences available in northern Spain.
Comillas has the second unusual thing on this list. El Capricho by Gaudí, his first major independent work and one of the earliest examples of the visual language he would develop across his career, sitting in a small Cantabrian coastal town. For anyone interested in Gaudí beyond the Sagrada Família, seeing this early building and understanding that it predates his Barcelona masterworks by a decade is genuinely revelatory.
Stargazing
The Cantabrian mountains behind the coast provide dark sky conditions significantly better than the coastal strip. The Picos de Europa area, with its high altitude terrain and minimal light pollution, offers exceptional conditions on clear nights. The valley around Potes and the high plateaus above the Fuente Dé cable car station are among the darkest accessible areas in northern Spain. The Atlantic weather pattern means cloud cover is a real consideration but the clear nights when they come are extraordinary. For certified dark sky destinations across Spain, our complete stargazing guide covers all regions.
