Cantabria is the smallest region on Spain's northern coast, wedged between Asturias to the west, the Basque Country to the east, and the Picos de Europa and Castilla y León to the south. Small as it is, it contains an astonishing range of landscapes, some of Spain's most significant prehistoric art, a stretch of Atlantic coastline with exceptional beaches, and a capital city that's widely considered one of the most enjoyable in the north.
Most travelers pass through Cantabria on their way somewhere else. That's their loss — and your gain.
Santander: The Elegant Bay City
Santander sits on a long peninsula jutting into one of Spain's most beautiful natural bays. The city is airy and open, with a broad maritime promenade, excellent beaches — El Sardinero is the most famous, a long sweep of golden sand that faces the open sea — and an easy, unhurried atmosphere that's uncommon in major Spanish cities.
The Magdalena Peninsula, jutting into the bay, was once the site of a royal summer palace and now houses the International Menendez Pelayo University. Its gardens and clifftop paths offer extraordinary views across the water to the mountains of the Picos de Europa on clear days — a combination of sea and high peaks that's uniquely Cantabrian.
The city was largely destroyed by a catastrophic fire in 1941 and rebuilt in a style that blends early 20th-century architecture with postwar functionalism. This gives Santander a slightly different character from other northern Spanish cities — more open, less medieval — but the old harbor area and surrounding streets still have genuine charm, and the seafood market by the port is outstanding.
Santander sits just west of País Vasco — the two regions share the Cantabrian coast and a food culture that runs along the same latitude. San Sebastián is about two hours east by car, making a combined trip natural.
Altamira: The Sistine Chapel of Prehistory
No trip to Cantabria is complete without a visit to Altamira, near the town of Santillana del Mar. The original cave — discovered in 1879 and containing paintings of bison, horses, and deer up to 36,000 years old — is closed to protect the art, but the Museo de Altamira contains an exquisitely faithful replica (the Neocueva) that conveys the full impact of the originals. The ceiling paintings are among the greatest achievements in the entire history of human art.
Santillana del Mar itself is one of Spain's most beautiful villages — a perfectly preserved medieval town of golden stone, with cobbled streets, Romanesque churches, and aristocratic palaces. It's been called 'the town of three lies' — not saintly (it was named for Santa Juliana, not a saint), not flat (it's on a hill), and not by the sea (it's two kilometers inland). Jean-Paul Sartre apparently called it the most beautiful village in Spain. That's worth investigating.
Tickets must be booked in advance through the official Altamira Neocueva website — entry to the replica cave (the original is closed to the public to preserve the paintings) sells out regularly, especially on summer weekends.
Cantabria has some of the finest beaches in Spain — broad, clean, backed by green hills rather than concrete developments. Playa de Oyambre is a long wild beach within a natural park. Playa de Langre sits at the base of dramatic red cliffs. The beaches around Castro Urdiales, near the Basque border, are sheltered and excellent.
San Vicente de la Barquera is one of the most striking towns on the entire north coast — a medieval fishing port with a castle, a Romanesque-Gothic church, and an estuary view that's been painted by artists for centuries. The seafood here — particularly the merluza en salsa verde (hake in green sauce) — is exceptional.
One more surprise on this coast: just inland near Cabezón de la Sal is a forest of nearly 850 giant redwoods and sequoias, planted in the 1940s and now among the tallest trees in Europe. Walking through it feels completely transplanted from Northern California — a strange, quiet grove that has nothing to do with the rest of Cantabria's landscape, and one of the more surreal short detours on this coast.
The full Atlantic coastline — from the Basque Country through Cantabria and Asturias to Galicia — is one of the great road trips in Spain. The 10-Day Northern Spain Road Trip covers the full route with logistics.
The Picos de Europa: Cantabria's Mountain Wall
Cantabria shares the Picos de Europa with Asturias and Castilla y León. The Cantabrian face of the mountains is accessed from the Liebana valley — a particularly beautiful area, warmer and more sheltered than the Asturian side, where the microclimate allows the cultivation of wine grapes. The Parador de Fuente Dé, at the foot of a 800-meter vertical cliff accessible by cable car, is one of the most dramatically situated hotels in Spain.
The cable car at Fuente Dé rises in four minutes to the high alpine plateau above, where walking trails lead through extraordinary limestone landscape to views that stretch on clear days all the way to the sea. It's one of the most dramatic ascents in the country.
The Picos de Europa straddle three regions — Cantabria, Asturias to the west, and Castilla y León to the south. The southern approach through León gives a completely different angle on the same mountains.
The Valley of Liebana and Potes
The Liebana valley, in the southern reaches of Cantabria, is one of Spain's lesser-known treasures. The small town of Potes is a charming base for exploring the area, with medieval towers, a lively market, and restaurants serving the valley's famous orujo (a fiery grape brandy) and the exceptional Picos de Europa cheese.
The Monastery of Santo Toribio de Liebana, above Potes, is one of Christendom's great pilgrimage sites — it claims to hold the largest relic of the True Cross in the world. In Jubilee years, pilgrims flock here as they do to Santiago, making the Camino Lebániego one of Spain's secondary pilgrimage routes.
What to Eat and Drink in Cantabria
Cantabria's food is defined by the sea and the mountain. Anchovies from Santoña are among the best in the world — packed in olive oil, they bear no resemblance to the tinned anchovies you've had elsewhere. Bonito del Norte, the white tuna caught in summer off the Cantabrian coast, is another staple. Eat it fresh when you can.
From the mountains: cocido montañés, a hearty stew of white beans, cabbage, and pork that belongs to the cold-weather interior. Sobao pasiego and quesada pasiega are the sweet baked goods of the Pasiegos valleys — butter-rich, dense, and worth bringing home.
The dairy here is exceptional. Cantabria produces some of the best butter and cream in Spain, and the cheeses — particularly the smoked Quesucos de Liébana from the valley near Potes — are outstanding. Orujo, the grape spirit of the Liébana valley, finishes most meals in the mountains.
In Santander, the market and the old fishing quarter around the port are the places to eat. Order whatever came in that morning.
The orujo of the Liébana valley is Cantabria's answer to grappa — distilled from grape skins, served after dinner in the mountain towns. The broader story of Spain's regional drinks is covered in Spain's Wine Regions guide — including the Atlantic wine culture that extends from Cantabria through Asturias into Galicia.
A car is the only practical way to explore Cantabria properly — the coast, the Picos, and the valley towns are all spread across narrow mountain roads. What to know before you drive in Spain covers the rules and what's different from driving in the US.
For official visitor information and travel resources for Cantabria, the Turismo de Cantabria is the best starting point for itineraries, events, and local guides.

Just over the mountains from Asturias's Vaqueiro cattle herders, Cantabria has its own ancient pastoral tradition in the Pasiegos of the Pas valley — seasonal cattle herders who built a whole culture around following the grass between mountain altitudes. A guide to the Pasiegos is coming to Travel-Casa shortly.
The mountains of Cantabria are home to one of the most extraordinary pastoral traditions in Spain. The Pasiegos of the Pas valley are semi-nomadic cattle herders who spent centuries moving their families and animals between stone farmhouses at different altitudes, following the grass. Their valley, about an hour south of Santander, is one of the most beautiful and culturally distinct corners of the north, and the sobao pasiego, their buttery sponge cake, is one of the best things you will eat here.
