Canyons and gorges of the Alto Tajo

Canyons and gorges define the hallmark landscape of the Alto Tajo: deep chasms carved by the Tagus and its tributaries into grey limestone or vibrant red sandstone (rodeno). Famous examples include the Barranco de la Hoz, the Arandilla gorge, and the Hundido de Armallones, explored on foot or from dizzying cliff viewpoints.

The Alto Tajo boasts two main canyon landscapes: limestone gorges, steep and grey, such as those along the Tagus itself or the Hundido de Armallones; and rodeno sandstone gorges, fiery red and bristling with towers and needles, such as the Barranco de la Hoz or the Arandilla valley.

Life on the cliff faces

These precipices provide sanctuary for cliff-nesting birds of prey, while riverside gallery forests offer shade and coolness along the valley floors even in August.

Practical advice

Spring and autumn offer ideal temperatures. In summer, walk during the early morning hours. After heavy downpours, canyon beds may carry runoff or mud.

Frequently asked questions

What is the difference between a hoz and a barranco?

Locally they are used almost interchangeably. A hoz usually refers to a narrow, entrenched river gorge between vertical rock walls; a barranco is a broader term for a deep mountain ravine.

Why are some canyons strikingly red?

Because they are cut through Triassic sandstone and conglomerates rich in iron oxide, known as rodeno. The pale grey or whitish cliffs consist of limestone or dolomite.
