GEOLAG Routes
Opposition Exam Preparation
Geology courses for teaching examination candidates in the Biology and Geology specialty.
GEOLAG
is an initiative that aims to make the Geology of the Cantabrian Range known to all audiences in an accessible way, without losing scientific rigor. In this way, you will learn the History of our Earth and how the landscapes that surround us were formed.
GEOLAG will answer your questions and those of your children such as… How are volcanoes formed? Why do earthquakes occur? Do continents move? Why are there fossils in the mountains? How did life arise on Earth?
To answer these and other questions, GEOLAG relies on its own graphic material and simple language, attempting to translate the scientific language that sometimes proves difficult to understand for audiences unfamiliar with geology.
GEOLAG has designed different activities and services for all ages so that you can learn more about the planet where we live. Our excursions, workshops, talks, camps, training courses, and educational materials are designed to make it very easy for you.
Geotourism
in Asturias
Discover the landscape with a different perspective: science, territory, and emotion in every route.
What is geotourism
Geotourism is a way of understanding a territory through its geology, its landscapes, and the natural processes that have shaped them. It is not just about observing rocks or landforms, but about interpreting the environment to understand why a place is as it is, how it has evolved over time, and what relationship it maintains with biodiversity, human history, and local identity.
Geological heritage and conservation
Geotourism is also a conservation tool. When a landscape is understood, it is valued more. That is why we work with the idea that disseminating geodiversity is a way of protecting it. Rocks, fossils, minerals, caves, landforms, and geological processes are part of a natural and cultural heritage that deserves to be known, respected, and transmitted.
Types of geotourism in Asturias
Geotourism in Asturias can be experienced from multiple perspectives: paleontological, archaeological, mining, speleological, or urban. Each of them allows us to discover how geology relates to culture, history, landscape, and daily life, always from a rigorous and respectful interpretation of the environment.
The geological attractions of Asturias allow for the development of very diverse experiences: from interest in fossils and minerals to visits to caves, karst landscapes, sites with archaeological significance, mining-industrial heritage, or urban tours focused on the rocks and fossils present in buildings and pavements. This variety makes geotourism a rich, cross-cutting, and adaptable proposal for different audiences, from families and educational centers to hikers, cultural travelers, or people with scientific interests.
GEOtourism, nature, culture, and scientific outreach
The history of the Earth is written in the Asturian landscape. At GEOLAG, we help you read it. We transform the territory into a comprehensible, exciting, and well-told experience so that each route is much more than a visit: it is a way of seeing Asturias with different eyes.
Discover the landscape with a different perspective:
science, territory, and emotion in every route.
Why Asturias is an exceptional destination
Few places combine such visible and spectacular geology in such a diverse space. Asturias offers rugged coastline, karst systems, large gorges, traces of the glacial past, caves, fossil deposits, mining heritage, and landscapes shaped over millions of years. This richness makes the region an extraordinary setting for experiencing geotourism with depth, beauty, and meaning.
A landscape that is interpreted
Some major geotourism attractions of Asturias
Asturias brings together numerous sites of great interest, from the blowholes and tidal sinkholes of the eastern coast to the estuaries of Barayo, Villaviciosa, and the Eo; from waterfalls and natural lakes to caves, chasms, gorges, and reference karst landscapes in the Cantabrian Range. Added to this are paleontological deposits, points of archaeological interest, and significant mining and industrial heritage.
Experiences and lines of work of GEOLAG
Asturias and the Geosites Network
Asturias has sites and geological contexts of international relevance integrated into the Geosites Network, a fundamental reference for identifying locations where the history of the Earth is exceptionally preserved. The presence of these contexts confirms the enormous scientific, educational, and landscape value of the Asturian territory, and reinforces its potential as a quality geotourism destination.
Beyond their specialized interest, Geosites help explain to the general public why certain landscapes, outcrops, caves, geological structures, or deposits are unique on a national and international scale. Incorporating this idea into the new website allows us to convey that Asturias is not only a beautiful territory, but a space with recognized geological heritage worthy of being interpreted, protected, and shared.
Real GEOLAG experiences
Jesus Sosa delgadoTrustindex verifica que la fuente original de la reseña sea Google. He sido alumno del curso de Mapas Geológicos + Historia Geológica durante el curso 2025-26, y solo puedo tener buenas palabras para la profesora Luna. Siempre me había costado muchísimo la geología y, sinceramente, era una asignatura que no me gustaba demasiado porque me parecía muy difícil. Sin embargo, gracias a Luna no solo ha empezado a gustarme, sino que ahora estoy realmente motivado con ella. Luna es una profesora súper amable y cercana en las clases. Se adapta perfectamente incluso si partes de un nivel 0, y consigue que conceptos que parecían imposibles se entiendan de forma clara y sencilla. Nunca pensé que llegaría el día en que un mapa geológico dejara de parecerme “un libro en chino o japonés”, y ahora puedo entenderlos perfectamente. Además, en este curso no solo se aprende muchísimo sobre mapas y cortes geológicos, sino también sobre geomorfología, área en la que Luna es especialista y transmite muchísimo conocimiento. Recomiendo este curso muchísimo a cualquier opositor que esté preparando las oposiciones de secundaria de Biología y Geología. Sin duda, ha sido una de las mejores decisiones de mi preparación. OlgaTrustindex verifica que la fuente original de la reseña sea Google. Un trabajo de 10 y una profesora excelente. Paula CabreroTrustindex verifica que la fuente original de la reseña sea Google. Una experiencia totalmente recomendable. Las rutas de GEOLAG son mucho más que un paseo, son una auténtica clase de geología al aire libre, explicada de forma amena y para todos los públicos. Se nota la pasión y el conocimiento que transmite Luna en cada parada. Descubrimos paisajes espectaculares entendiendo cómo se formaron y su historia geológica, algo que normalmente pasa desapercibido. Ideal para familias, curiosos o amantes de la naturaleza. Sin duda, repetiré en otra de sus rutas. Sara FraileTrustindex verifica que la fuente original de la reseña sea Google. Una jornada muy interesante aprendiendo mucho de manera lúdica y muy amena para los niños. Maite MoraTrustindex verifica que la fuente original de la reseña sea Google. Una vez más Luna, con su pasión y conocimientos, hace que la geología pueda comprenderse, al mismo tiempo que la lectura del paisaje, se transforma en el cuento de la tierra. Celia ManzanoTrustindex verifica que la fuente original de la reseña sea Google. He realizado curso de Historias geológicas y muy muy contenta. Además Luna siempre dispuesta a resolver dudas. Sin duda 100% recomendable. Sara Fernández RodríguezTrustindex verifica que la fuente original de la reseña sea Google. Muy muy contenta con Geolag, tanto las clases con Luna como con otros especialistas. Susana GonzálezTrustindex verifica que la fuente original de la reseña sea Google. He realizado varios cursos intensivos con Geolag y me han resultado de gran ayuda, tanto para impartir las clases de Geología (2º Bachillerato), como para la oposición de Biología y Geología. Siguiré con Geolag en mi formación.

Las Catedrales: Cliffs in Transformation
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.

Gold in Asturias: Salave and the Silva Lakes
Salave hides one of Asturias’ great geological treasures: gold, Roman mining, and a landscape shaped by water. An educational route to discover how the Silva Lakes formed and why this area deserves to be protected.
