The Iberian System that runs through the north of the province of Soria is a paradise of surprises, but it is in the Montes Claros mountain range where a very special uniqueness is preserved. The Garagüeta holly tree is the largest in the Iberian Peninsula and has extraordinary ecological value both for the number of specimens and their size.

Being a natural space populated only by holly trees, there is a theory that its origin may lie in the disappearance of oak and beech forests as they are species that it normally accompanies.

In its labyrinthine growth it forms galleries in which a large number of animals take refuge and in autumn, when the intense colors of the fruits explode, they easily find food.
