Where Is the Cantabrian Sea?

The Cantabrian Sea forms part of the Atlantic Ocean and borders the Spanish regions of Galicia, Asturias, Cantabria, and the Basque Country. It also touches a small part of southwestern France. This coastal stretch is often referred to as "Green Spain" (España Verde) due to its lush landscapes nourished by the sea’s moist winds.

Why Visit the Cantabrian Sea?

1. Spectacular Natural Beauty

The Cantabrian coastline is famous for its dramatic cliffs, secluded coves, and sandy beaches. Unlike the crowded Mediterranean resorts, the Cantabrian beaches are quieter, often framed by mountains like the Picos de Europa, creating postcard-perfect scenery.

2. Authentic Spanish Culture

The towns along the Cantabrian Sea — such as Santander, San Sebastián, Llanes, and Castro Urdiales — offer a deep dive into authentic Spanish and Basque traditions. Here, you can experience local cuisine (fresh seafood, pintxos, and cider), historic old towns, and lively festivals.

3. Adventure and Activities

The Cantabrian Sea is perfect for surfing, sailing, fishing, and hiking. Popular surf spots like Sopelana and Rodiles Beach draw surfers from around the world, while the Camino de Santiago's Northern Way (Camino del Norte) follows the coastline, offering incredible hiking experiences.

4. Rich Marine Biodiversity

The waters of the Cantabrian Sea are home to diverse marine life. Whale watching tours, particularly in Galicia and Asturias, are becoming increasingly popular. Fishing has been a way of life here for centuries, and you can still see traditional methods in small villages.
