N634 is one of the Spanish best coastal roads

Tucked away on northern Spain, the scenic N634 Road is said to be one of the world's best coastal drives, running along the Cantabrian Sea. It was rewarded as one of the world's best roads of 2015. 

N634

The road is totally paved. This exhilarating drive with stunning coastal scenery runs through the autonomous communities of Basque Country, Cantabria, Asturias and Galicia. The road is 730 km (453 miles) long running from Santiago de Compostela, the capital of the autonomous community of Galicia, in northwestern Spain to San Sebastián, a coastal city in the Basque Autonomous Community.

This is a remarkable road trip. Remember to bring your camera. The road is totally paved, very well surfaced, and runs along the Cantabrian Sea. This spectacular drive leads you from the shorelines to gorges and rugged mountains. Make sure you leave enough time to make plenty of stops. Along the way, sometimes you are near the sea and on other occasions you go through the interior. The road dips in and out of the Atlantic and wanders through many seaside villages. It’s a favorite road for bikers on weekends and summer holidays.
The final stretch of the route, about 15 km along the Guipuzcoan coast in the north of Spain in the Basque Country, between the cities of Zarauz (the longest beach on the Gipuzkoan coast) and Zumaya, is considered one of the most beautiful Spanish coastal drives.
