A journey deep into the origins of Spain
Northern Spain is a land of green mountains, dramatic coastlines and ancient landscapes. But some of its most remarkable stories are hidden beneath the surface.
Across Cantabria, Asturias, the Basque Country and inland towards Burgos, caves and archaeological sites preserve extraordinary evidence of human life stretching back tens of thousands, and in some places hundreds of thousands, of years. Here, the past is not simply displayed in museums. It is found inside mountains, beneath forests and along landscapes that have changed surprisingly little.
For travellers interested in history, archaeology and the origins of human culture, northern Spain offers experiences that go far beyond the traditional sights.
Altamira and the first great artists
Few prehistoric sites are as famous as the Cave of Altamira, near Santillana del Mar in Cantabria.
Discovered in the nineteenth century, Altamira became the first place where Paleolithic cave art was recognised as such. Its famous polychrome paintings, particularly the bison, demonstrated an extraordinary level of artistic skill and changed our understanding of prehistoric humanity. The cave became a UNESCO World Heritage Site in 1985.
But Altamira is only part of a much larger story.
The UNESCO designation was extended in 2008 to include another seventeen decorated caves across Cantabria, Asturias and the Basque Country. Together, they form one of Europe’s most important concentrations of Paleolithic cave art, dating broadly from around 35,000 to 11,000 years ago.
That makes the northern coast something of an open-air — or rather, underground — archive of humanity’s earliest artistic expression.
Beneath the Cantabrian mountains
Some of these caves offer a very different experience from the celebrated Altamira.
Caves such as El Castillo, Las Monedas and La Pasiega in Cantabria, or Tito Bustillo in Asturias, contain paintings, engravings and traces of prehistoric occupation. Their locations also reveal something about the people who lived here: the mountains, rivers and coastline provided shelter, food and natural resources, creating a landscape in which human communities returned to the same places over many generations.
Then there is El Soplao.
Unlike Altamira, El Soplao is not principally an archaeological site. Its importance lies in the extraordinary geological formations hidden inside the mountain, together with its history as a mining site. Natural galleries extend for around 20 kilometres, alongside almost 30 kilometres of mining galleries, creating an underground world of stalactites, eccentric formations and vast chambers.
It is a completely different way of experiencing the ancient landscape: not the traces left by humans, but the forces of nature that have been shaping northern Spain for millions of years.
Atapuerca and the story of humanity
Further inland, near Burgos, the story reaches much deeper into human history.
The archaeological sites of the Sierra de Atapuerca contain an exceptional fossil record extending back almost one million years. The discoveries here provide evidence of some of the earliest human communities in Europe and have made Atapuerca one of the world’s most significant archaeological sites.
And the ancient story continues further east. In La Rioja, particularly around Enciso and the Cidacos Valley, thousands of dinosaur footprints have been preserved in the landscape, offering a glimpse of a world that existed millions of years before humans appeared.
Together, these sites create an extraordinary sense of scale: from dinosaurs and early human populations to the first artists who left their mark on the walls of northern Spain’s caves.
Experiencing the ancient north
What makes these places particularly fascinating is their setting.
A day exploring prehistoric caves can sit naturally within a journey through northern Spain’s mountains, fishing villages, historic towns and Atlantic coastline. The landscape becomes part of the story, helping to explain why people lived here, travelled through these valleys and returned to these caves for thousands of years.
For us, these are not simply archaeological stops to tick off a route. They are places where history feels tangible — sometimes through a painted bison on a cave wall, sometimes through a fossil buried deep beneath the earth, and sometimes through the extraordinary geology of a mountain.
Northern Spain offers the chance to travel not only across a landscape, but back through time.
