Karstic landscape

At the head of the Roncal Valley is the Larra massif, an immense mass of limestone formed 65 million years ago. Then, the area was formed by a warm and shallow sea, at whose bottom the sediments and remains of the living beings that populated it were deposited. Subsequently, water, snow, ice and wind have externally modeled a particular relief, a chaos of rock dotted here and there by black pines.
