The coastal regions of Galicia and Asturias are characterized by unique geological landmarks, tidal dependencies, and significant ecological importance. In Galicia, the Playa de las Catedrales in Ribadeo features stone arches exceeding 30 meters, with access regulated by permits to protect the environment. The region also benefits from the Canary upwelling, a rare oceanographic phenomenon that brings nutrient-rich waters to the surface, supporting major shellfish production.

In the border region between Asturias and Galicia, the Playa de Arnao is part of the Ría del Eo Partial Natural Reserve, which holds European protections such as Special Areas of Conservation. Management of this area focuses on dune flora preservation and sustainable tourism. Additionally, the Lumebó cove in Ferrol presents a rugged landscape that is only accessible during low tide, with local authorities noting that access is “very difficult” due to the steep terrain.
