It is located in the limit of the Province of Jaen, adjacent to the Natural Park of Cazorla, Segura and Las Villas. It is a mountain range full of contrasts. Its main characteristic is its spectacular relief due to the limestone nature of its ground, with heihts above the 2000 metres, and also due to the erosion of the water. It is full of grottos and galleries, such as La Cueva del Muerto in Sierra Seca, where you can contemplate capricious rock formations, or La Cueva de Don Fernando, the deepest and longest in Granada, full of galleries and rock rooms of deep beauty, such as La Sala de la Colada.
It is crossed from North to South by the Castril River, being the landscape full of waterfalls, canyons, grottos and galleries. Humbleness is an important factor, as well as the difficulty of the ground, both of which shape the vegetable and animal life which develops in the area. There are also lots of springs such as Juan Ruiz, Tubos, La Magdalena or Lézar.
In the north area of Sierra Seca there is a small area where almost the whole year a small lake is formed due to the accumulation of rain water and of snow water. This is and interesting area because it grows there natural grass of a great botanical diversity. You can also find different species of trees such as pine trees, some of which can reach the height of 40 metres, oak trees and some other species of trees which grow in wetter grounds, such as the cliffs of Túnez and Magdalena. There are also different species of bushes in the area.
Thanks to the variety of atmosphere of the mountain range the fauna is also very diverse, being the vulture, which finds here the south-eastern limit of the Peninsula, of great importante. There are also other animal species which live in the area, being the mountain goat, the deer, the wild pig and the lynx some of the species on the ground, the eagle and the hawk some of the species in the air and the common trout and its natural hunters: the otter or the heron some of the species in the water.
