An extension of 421,1 hectares in the municipal terms of Teguise and Haría. The protection purpose is the ravine landscape. Scarce longitude, only 4 km. It starts from the peak of Famara Old Massif, next to the Peñas del Chache, being developed in direction NW -SE. It should be grouped together with the Valley of Temisa and the Palomo Valley as a landscape unit. They are dug ravines in old materials from Serie 1.

A series of remodelling has been found in the periphery of the massif with the emergence of volcanoes from Series 11 and III along the coast. These remodelling have caused the plugging up of the ravines in the way out to the sea. As the formation of basins have taken place where sediments are accumulated. An interesting process of landscape evolution can be observed thanks to the opening of new basins that cut the obstacles.

Beside Risco de Famara, the most abrupt relief of the island is found here, being conserved as an interesting natural patrimony especially faunistic. A number of 95 species have been found in this place, of which 34 are vertebrate, prevailing the birds with 25 species; representing 75% of the ones that nest in the island. To highlight: The cory's shearwater, in a non coast surroundings. The monochromatic marlet, in non humanized areas, and the common owl. Also to stand out the presence of birds in danger of extinction like the guirre and other predators such as the Berberia's hawk.

From the floristic point of view, the presence of certain endemism of great interest highlights. However the majority of this space has been colonized by communities of substitution due to the intense use of agriculture which were subjected in previous years. The presence of relatively evolved floors and protected areas from wind and isolation allows the vegetation development of arboreal presence.

The presence of water in the ravine basin during the good part of the year and the easy access allowed the aboriginal population's establishment. Very few testimonies have arrived from this presence due to the great work of later agricultural transformation.

The isolation has allowed the life of a traditional agricultural landscape, although enough altered by the action of the time and the elements. Man's action is perceptible everywhere. It is expressed in an austere landscape in which the natural elements from the landscape are integrated and the transforming actions have great harmony and ethnographic value.

The rudimentary hydraulic works are a good example of taking advantage of the scarce rain. Stone walls are built in the basins of the ravines to form small terraces, called nateros. These have a mission to impede the deterioration of the main ravine from the avalanches of water. Also The nateros channel the water to the biggest terraces at the bottom of the ravine, called gavias, to be planted.
