A point-to-point self-drive along Spain's green Cantabrian coast, from the pintxos bars of San Sebastián through the Picos de Europa to the pilgrim city of Santiago de Compostela in twelve days.
This northern Spain road trip itinerary follows España Verde, the green Spain that most visitors to the country never see. Instead of the dry plains and the Mediterranean, the north is Atlantic: a coast of estuaries and cliffs, backed within an hour by the limestone peaks of the Picos de Europa, and fed by four of Spain's best regional kitchens. In twelve days you drive from the Basque Country through Cantabria and Asturias into Galicia, from the pintxos bars of San Sebastián to the cathedral square in Santiago de Compostela.
The route runs one way, west, and it does not double back. Most travellers fly into Bilbao or Biarritz at the eastern end and out of Santiago (SCQ) at the western one, picking up and dropping off a hire car in different cities. The driving is genuinely relaxed: the A-8 autovía shadows the whole coast and is toll-free through Cantabria and Asturias, and no single leg on this route runs beyond about two and a half hours.
The stops run in order: San Sebastián, Bilbao, Santander, Cangas de Onís for the Picos de Europa, Oviedo, Ribadeo, and Santiago de Compostela. A standard car handles every road; the only toll on the whole trip is the AP-8 between San Sebastián and Bilbao. Green Spain is also popular campervan country, with plenty of coastal aires and campsites.
San Sebastián, or Donostia in Basque, is the most polished city on this coast, wrapped around the near-perfect arc of La Concha beach. Two headlands close off the bay: Monte Urgull, topped by a castle and a stone Christ, and Monte Igueldo, reached by a century-old funicular that ends at a small vintage fairground with the classic postcard view.
The old town, the Parte Vieja, is the reason to give the city two nights. It has one of the highest concentrations of Michelin stars anywhere in the world, but the everyday pleasure is the pintxos bars. The custom is to order one or two small plates and a short glass of the local txakoli wine, then move to the next bar. Look for the gilda, a skewer of olive, anchovy and guindilla pepper that started the whole tradition, along with grilled txipirones and slabs of seared foie.
Beyond the food, the San Telmo Museum in a former convent covers Basque history and society, and the Zurriola beach east of the river draws surfers. Save a slow morning for simply walking La Concha end to end.
A 10-day southern France loop: Marseille's Calanques, Arles' Roman ruins and the Camargue, Saint-Tropez's beaches, and three nights on the French Riviera at Nice.
The drive west to Bilbao is about 100 km and takes a little over an hour on the AP-8, the one toll road of the trip. Bilbao is the story of a city reinvented. A generation ago it was a declining industrial port; then Frank Gehry's Guggenheim landed on the riverfront in 1997 and pulled in the world.
The titanium building is the headline, and you do not need a ticket to appreciate it, though the modern-art collection inside rewards a couple of hours. Around it, the riverside walk is free and studded with public art: Louise Bourgeois's towering bronze spider Maman, and Jeff Koons's flower-covered Puppy standing guard at the entrance. Across the river, the Casco Viejo, the old town of the Seven Streets, holds the Ribera covered market and the tight tapas bars that locals prefer to the tourist-facing riverside.
For a wider view, the Artxanda funicular climbs the northern hill in three minutes to a terrace over the whole city bowl. One night is enough to take in Bilbao before the coast proper begins.
Bilbao to Santander is another easy coastal hour, and Santander makes the ideal two-night base for Cantabria. The city itself is a genteel seaside resort, strung along the golden Sardinero beaches beneath the Magdalena Palace, a royal summer residence on its own green headland. It is pleasant rather than essential, which is the point: the real riches are the day trips west.
Santillana del Mar, half an hour away, is one of the best-preserved medieval villages in Spain, a compact grid of cobbled lanes and honey-coloured stone manor houses with no through traffic. On its edge sits Altamira, the cave whose 36,000-year-old bison paintings are so important and so fragile that the original is closed to the public. The museum's Neocueva is an exact replica that recreates the ceiling in full, and it is genuinely moving.
Further west, Comillas adds a Modernist surprise: El Capricho, an early villa by Antoni Gaudí, sits among the town's beaches and hilltop palace. With more time, the fishing village of San Vicente de la Barquera and the cliffs around it round out the Cantabrian coast.
At Santander the route turns inland and climbs. The drive to Cangas de Onís takes around 90 minutes, and it swaps the coast for the most dramatic mountains in northern Spain. Cangas, a small town under a graceful Roman-style bridge, is the classic western base for the Picos de Europa National Park.
The set-piece is Covadonga. A winding road climbs from the basilica to two glacial lakes, Enol and Ercina, ringed by bare limestone peaks and grazing cattle. Just below sits the Basilica of Covadonga and the Holy Cave built into the cliff, where a shrine to the Virgin marks the spot where, according to tradition, the Christian reconquest of Spain began in the eighth century. In summer the narrow lakes road closes to private cars and a shuttle runs from Cangas instead, so go early or plan around the bus.
The second day is for walking. The Ruta del Cares is one of the great day hikes in Spain, a path blasted into the gorge walls between Poncebos and Caín, following the river past tunnels and hanging bridges. The full route is around 22 km there and back, but even two hours in reaches the finest scenery. For less effort, the Fuente Dé cable car on the eastern side of the massif lifts you 750 metres to a high viewpoint in minutes.
Cangas de Onís to Oviedo is a short hour, dropping out of the mountains to the Asturian capital. Oviedo is dignified and compact, an easy city to walk in an afternoon and evening. Its Gothic cathedral holds the Cámara Santa, a treasury of early medieval Asturian goldwork, but the buildings that matter most sit on Monte Naranco just outside the centre.
Santa María del Naranco and San Miguel de Lillo were built in the 840s as a royal palace and its chapel, and they are among the oldest intact buildings in Spain. Their tall, slender proportions belong to the pre-Romanesque Asturian style that predates and helped shape the Romanesque architecture that spread across Europe later, and they carry UNESCO World Heritage status for it.
The evening is for cider. Calle Gascona is lined with sidrerías, and the ritual is theatrical: the waiter holds the bottle high above their head and the glass low at the hip, pouring a splash, the culín, from height to aerate the flat Asturian cider. You drink it in one go and hand the glass back for the next.
The leg west from Oviedo into Galicia is the longest of the trip at around two hours, but it is easily broken. The Asturian coast between here and the regional border is dotted with photogenic fishing towns: Cudillero, a jumble of painted houses stacked around a tiny harbour, and Luarca, wrapped around its own working port, both reward a coffee stop.
Ribadeo sits just over the border in Galicia, at the mouth of the Eo estuary, and it is the base for the single most photographed beach on this coast. Playa de las Catedrales, the Beach of the Cathedrals, is a stretch of cliff that the Atlantic has hollowed into arches, flying buttresses and sea caves. The catch, and it is a serious one, is the tide: the arches only stand clear at low water, and at high tide the beach disappears entirely. Check the tide tables before you go, and note that in summer and over Easter you need a free access permit booked online in advance.
The final drive, roughly two hours inland from Ribadeo, ends at the spiritual full stop of the whole trip. Santiago de Compostela is the end of the Camino de Santiago, the pilgrimage that has drawn walkers across northern Spain for more than a thousand years, and its granite old town is a UNESCO World Heritage Site.
Everything funnels toward the cathedral and the enormous Praza do Obradoiro in front of it. Standing in the square in the late afternoon, you watch pilgrims arrive on foot and by bike, often emotional, having walked for weeks to get here. Inside, the cathedral holds the shrine of Saint James; a rooftop tour, booked ahead, walks you across the granite roofs above the crowds.
Two nights let Santiago breathe. Beyond the cathedral, the Mercado de Abastos is one of the best food markets in Spain, the place to try Galician octopus, pulpo á feira, dressed with paprika and olive oil, and the almond tart de Santiago. The Alameda park, a short climb from the centre, gives the classic postcard view of the cathedral spires above the rooftops, especially at dusk.
The defining fact of Green Spain is that it is green because it rains. This is the wettest corner of the country, and the landscape you come for depends on that Atlantic weather. The best windows are late spring and early autumn.
May and June bring long days, wildflowers in the Picos, and warm but not crowded coasts, with a real chance of clear mountain views. September and early October are the other sweet spot: the sea stays swimmable, the summer crowds thin out, and the Galician and Asturian harvests fill the markets.
July and August are the warmest and busiest months, when Spanish families take their own holidays on this coast. The beaches are lively, but Playa de las Catedrales requires its permit, the Covadonga lakes road is on shuttle-only access, and accommodation books up. Winter is quiet and often beautiful, but expect rain, short days, and snow closing the high mountain roads.
The A-8 autovía runs the length of this coast and is free through Cantabria, Asturias and Galicia; only the AP-8 between San Sebastián and Bilbao charges a toll. Roads are modern and well signed throughout, and a standard car is fine for every stop, including the Covadonga climb outside the summer closure.
Park outside the old towns. San Sebastián, Bilbao, Oviedo and Santiago all have paid garages just beyond the pedestrian centres, and driving into the historic cores is restricted and not worth the stress. Pick up your hire car in Bilbao after San Sebastián if you would rather not drive in the Basque cities at all, or drop it in Santiago and fly out.
Book the fragile, capacity-limited sights ahead: the Altamira Neocueva near Santander, the Playa de las Catedrales permit in high season, and the Santiago cathedral rooftop tour. Everything else on this northern Spain road trip itinerary rewards simply turning up, eating well, and letting the coast and the mountains set the pace.
