Alto Tajo Natural Park: Wildlife, Gorges and Dark Skies

The Alto Tajo Natural Park is our home. We live in Peñalén, a village inside the park, in the province of Guadalajara, about two hours by car from Madrid. This is the upper course of the River Tagus, the longest river in the Iberian Peninsula, where it cuts deep canyons through limestone.

What makes it special

  • Gorges and canyons: the river and its tributaries have carved dramatic gorges, locally called hoces, with cliffs where griffon vultures nest.
  • UNESCO Geopark: the area is part of the Molina-Alto Tajo UNESCO Global Geopark, recognised for its geology and fossils.
  • Dark skies: the Señorío de Molina, which includes the park, holds Starlight certification. Very few villages, almost no light pollution.
  • Old forests: Scots and maritime pines, and Spanish juniper (Juniperus thurifera), one of the longest-lived trees in Europe.
  • Empty: this is part of what Spaniards call la España vaciada, the emptied Spain. You will often have a whole valley to yourselves.

Wildlife and rewilding

Red deer, roe deer, wild boar, otters, griffon vultures, Egyptian vultures and golden eagles live here. In autumn, the deer rut fills the forest with roaring.

The Alto Tajo is also one of the main rewilding areas in Spain. Large grazers that had been missing for centuries are back:

  • Przewalski’s horses, the last wild horse on Earth, at Villanueva de Alcorón.
  • European bison, Europe’s largest land mammal, at El Recuenco.
  • Tauros and Serrano horses at the Mazarete estate.

What you can do here

  • Stargazing with a telescope, guided by a certified Starlight monitor.
  • Mushroom foraging in autumn and spring, permit included.
  • Interpreted walks through gorges and canyons, with the geology and wildlife explained as you go.
  • Birdwatching, from vulture cliffs to the high, cold plains where Dupont’s lark lives.
  • Local trades: the river log drivers who floated timber down the Tagus, the resin tappers and the shepherds of the juniper huts.

When to come

  • Autumn: the deer rut in September and October, mushrooms, and the riverside woods turning colour.
  • Winter: tracks in the snow, black truffle, courting vultures and the longest nights of the year for stars.
  • Spring: full rivers, returning migratory birds and spring mushrooms.
  • Summer: kayaking, early walks and warm nights under the Milky Way.

Frequently asked questions

Where is the Alto Tajo?
In the north-east of Castilla-La Mancha, mostly in the province of Guadalajara, about 2 hours by car from Madrid and Zaragoza.

Does the River Tagus start here?
No. It rises at Frías de Albarracín, in the Montes Universales in Teruel, and then crosses the Alto Tajo.

Can we visit without a car?
Public transport is very limited. Tell us how you are travelling and we will look at the options with you; we can also pick you up from your accommodation.
