Chaorna Historic Village

Highlight • Settlement

It is a charming town located to the south-east of the province of Soria. Among other beauties, it has a Muslim watchtower, a cave under the rock that is below the Tower, a very old church, a laundry room, a drinking trough, a fountain, an old fireplace, a bread oven, a forge, and even a bench (seat ) of style, Dalíliano. The Almugera stream or Chaorna stream runs through the same town, which, a few kilometers below, forms the beautiful ravine of the stairs, in whose lateral cliffs, there are some caves, such as the Cueva de la Mora, with a small entrance, but great depth and interior spaciousness. Chaorna is a town that deserves several visits.

Aire Tunnel

Highlight (Segment) • Structure

Many years ago, it was created by workers from Somaén who went every day to the Río Blanco Iron Ore Mine. Going through the tunnel made the path much shorter and easier. That was the reason for drilling into the mountain.
Today, it serves hikers and mountaineers to make the journey to La Mora Cave or the Río Blanco Reservoir easier.
It should be noted that the entrance and exit are low to prevent large animals from entering; it is necessary to enter and exit on all fours, using hands and knees. The interior of the tunnel is high. A headlamp is required. It is approximately 110 meters long.

Barranco de la Escalera

Highlight • Gorge

It is a beautiful place, but very jungle, with a large number of trees, fallen and undergrowth. However, you can walk well through it. It was generated by the Almuguera stream or Chaorna stream. Its name is due to the fact that in that area, the stream descends a great unevenness, and in one of its areas, it has produced on the ground, a kind of staircase in its descent. On both sides of the ravine there are two rock cliffs. In the cliffs there are some caves.

Their function was probably to defend the surrounding fields and the people who worked them.

Under the Castle rock there are some Caves or Shelters in the rocks,
