As Catedrais Beach, in Ribadeo, is much more than one of Galicia’s most visited landscapes. Its slate and schist cliffs, shaped by waves and tides, provide a live demonstration of how geology transforms the coastline. Arches, columns, fractures, and landslides turn this protected enclave into a window into our planet’s past and a natural laboratory for understanding coastal processes.
The Route of the Xanas lets you discover one of Asturias’ most spectacular gorges through a geological lens. A trail through limestone, sandstone, faults, folds and water-carved landscapes, ideal for interpreting the formation of this gorge between Proaza, Serandi and Pedroveya.
Discover Costa Quebrada, jewel of Cantabria and Natura 2000 Network. From San Juan de la Canal to Somocuevas, be amazed by its ancient islets and cliffs. A geological landscape that will captivate you!
The Asturian coast is a living landscape where beaches, cliffs, dunes, estuaries, and coastal platforms (rasas) tell the geological history of the northern Iberian Peninsula. Along its more than 350 km of coastline, between the Tinamayor and Eo estuaries, the variety of rocks and structures dictates the shape of the coast: from the cliffs and pebble beaches of the west to the limestone landscapes of the east, including the large sandy areas and dune systems fed by rivers. An educational journey to understand how the sea, rocks, sediments, and time have modeled one of the most diverse coastlines of the Cantabrian Sea.
The Samuel Path PR-AS-284 is a low-difficulty circular route that combines nature, geology, and local history between Llames de Pría, Cuerres, and Ribadesella. Along the Guadamía River, the path reveals a peaceful landscape of fertile plains, limestone formations, small waterfalls, and unique spots such as the medieval Mía bridge, with the option to extend the walk to the impressive Bufones de Pría.
Very close to Vega beach, in the town of Torre, lies the Puente del Arcu, a unique natural formation created by the erosion of the Acebo River on Carboniferous limestones. A short walk through the forest leads to this rock arch, an ancient section of a fluvial cave where subterranean features, such as stalactites and flag formations, are still preserved. Beneath the arch, the ruins of an old flour mill add human history to a geological spot as beautiful as it is unexpected.
