Alto Tajo geology

Alto Tajo belongs to the Molina-Alto Tajo UNESCO Global Geopark for its rich geological record: fossil-filled marine rocks, Triassic red sandstones, enormous folds, tufa forming today and karst landscapes. This list gathers atlas geological sites, many with panels and geological trails.

Walking Alto Tajo means crossing hundreds of millions of years. Here are ancient-sea fossils, Triassic river sandstones, folds bending entire rock layers, mesas and rocky passages sculpted by erosion, and tufa forming before our eyes.

Reading a rock

Notice three things: colour — iron red, limestone grey — layers, horizontal, tilted or folded, and what is inside, shells, traces or pebbles. That is enough to begin telling the place’s story.

Traces to keep reading

These places connect the theme with the territory’s stories. Choose a trace and open its page to follow the story.
