The site known as Cerrada del Utroo-Linarejos is an amazing natural work sculpted by the Guadalquivir River in the limestone that surrounds it. The path is walked on foot, allowing us to appreciate the sharp rocks and overlooks created by water over hundreds of thousands of years. It is a charming walk where the labiérnago, the cornicabra and the willow will accompany us to one of the most photographed places of the Natural Park Sierras de Cazorla, Segura and Las Villas: the "horse tail" or Cascada de Linarejos. The path, of 1.6 km, has a circular route to return to the road on a pleasant itinerary of about 45 minutes. It may be of interest to get to know the small town of Vadillo-Castril, where the former RIFE sawmill was and which today is the home of two agencies of great importance for the natural park: the School of Forest Capataces and the Forest Defense Centre.

The sector of the Cerrada de Utroo-Lancar de Linarejos is located in materials of the Prebetic of the Betic Cordillera. In particular, in the Cerrada de Utrero, the Guadalquivir River fits into limestone of the Superior Jurassic often dolomitised that develop constructive and destructive karmic forms at different scales.

The narrow river-karctic valley was carved during the quaternary along the axis of a synchronous N40E direction. The karctic canyon of the closed is one km long and has a profile scaled by the development of travertines and pozas. The walls of the valley are pulled by minor karmic forms of great beauty and spectacular lapiaces The setting of the Guadalquivir River has left the stream of Linarejos hanging producing an impressive waterfall, known as the Cascade of Linarejos. This water jump of several tens of meters develops a travertine mass with "horse tail" morphology and cascade facies. The Lanchar de Linarejos is located on the SE flank of the synclinal and features a sequence of lapiaces and structural alleys controlled by conjugated diaclases.

The river incision of the Borosa River in the Cretaceous limestone of Urgonian faces produces the strong fitting of the channel in this area, generating a narrow karmic valley with vertical walls more than 10 m in height and about 400 m in length.

This spectacular throat known as the Cerrada de Elias can be crossed over a pendant walkway several meters above the river, which is suspended on the vertical walls of the Cerrada.

They highlight the remains of the tower of tribute located in the courtyard of arms. It is worth taking advantage of the low levels of the reservoir to walk to the castle from the above-mentioned viewpoint.

The waterfall is located next to the Falcones (1448 m), mountain always visible from any street of Cazorla, and a natural stone wall "Los Castellones" (1,820 m), elevation as a fortress from where it is named. To appreciate the water leaps it will be necessary to climb up a narrow path that runs next to the slope of the stream where you will be accompanied by the cornicabra (Pistacia terebinthus), a very abundant species on this path. By moving along the path you will appreciate the impressive fall of water as soon as the limestone walls serve as slides.

We suggest:

• Next to the bridge from where the waterfall is seen, a right-hand road leads us to the control of Riogazas. It is a pleasant walk in which you will find a fountain called "The River" and another beautiful waterfall, that of the Magdalena. From here goes down a road to Cazorla.

In the Iruela you have to reach the square of the City Hall from where the road ascends towards the hotel Riogazas. 5 km from the Iruela and after two lookouts with meringeros there is a bridge. To the left we can see the Cascade of the Escaleruela.

Information and Observations

• We will have to leave the vehicle at the entrance of the lane because there is a barrier to avoid the passage of vehicles.
• The property through which the lane passes is private so it is not allowed to enter the lane with vehicle.

The upper part of the Borosa River, has a scalated profile for the development of pozas and waterfalls in which travertine terraces are formed with spectacular botroidal calcite morphologies that were precipitated during the most humid and warm periods of the Quaternary.

Although travertine appear throughout the river, the highest concentration is located in the sector between the organ jump and the electric power plant. Its formation is due to the precipitation of calcite caused by the tear-up of the river waters produced by the turbulent regime of the water leaps in the areas with the greatest slope. This precipitation occurs in areas of dense vegetation receding elements of plants and producing subvertical sheets known as cascade facies.

In particular this stretch of road runs almost air in the interflude of the valleys of the Guadalimar and the Guadalquivir. From this area you can see thousands of hectares of olive trees in a single look, framed by the horizons of Sierra Morena on one side, and Sierra de Segura and Sierra de Las Villas on the other.
