Celtic & Atlantic North

Legends of the green and misty coast

From the Celtic castro settlements of Galicia through the pre-Romanesque treasures of Asturias to the iron forges of the Basque Country, this route follows the Atlantic coast through Spain's greenest and most mythical landscapes.

Northern Spain is a different world from the sun-baked south. Here, the Atlantic climate creates a landscape of emerald green valleys, misty mountains, and a rugged coast battered by Europe's most powerful waves. The cultures of this coast — Galician, Asturian, Cantabrian, Basque — predate the Roman conquest and retain a distinct identity rooted in Celtic tradition, Atlantic trade, and a fierce independence from the kingdoms of the meseta.

This itinerary traces the entire Atlantic coast of Spain through 17 stops and approximately 1,200 kilometres, from the hórreo-lined waterfront of Combarro in Galicia to the Basque witch-trial village of Zugarramurdi near the French border. Along the way, you'll pass through the Picos de Europa — one of Europe's most spectacular mountain ranges — where the village of Bulnes remained inaccessible by road until a funicular was built in 2001. In Asturias, the landscape that sheltered the last Christian holdouts during the Muslim invasion has barely changed since Pelayo raised his standard at Covadonga in 722.

The Basque Country offers a dramatic contrast: industrial heritage intertwined with some of Europe's oldest human cultures. The Basque language (Euskara) predates all Indo-European languages and remains linguistically unclassified. The coastal fishing villages of Elantxobe, Mundaka, and Getaria feel like fragments of another continent — vertical, wave-battered, and fiercely proud. This is Spain's wild coast, and it demands to be experienced slowly.

Practical information

The route follows the A-8 motorway (Autovía del Cantábrico) for much of its length, with diversions onto mountain and coastal roads. Atlantic weather is unpredictable — pack layers and rain gear even in summer. Accommodation ranges from Galician pazos (manor houses) to Basque caseríos (farmhouses). The Bulnes funicular runs every 30 minutes and costs €22 round-trip. Try regional cuisine: pulpo á feira in Galicia, fabada in Asturias, cocido montañés in Cantabria, pintxos in the Basque Country.
