Quinto Real belongs to the Valleys of Erro, Baztan, Esteribar and Alduides. Deer, wild boar and foxes abound. Birds complete the long list of animals found in this leafy forest: the black woodpecker, the white-backed woodpecker, the woodcock, eagles, honey buzzards, vultures and lammergeiers.



The rutting season is without doubt the most important event at the beginning of autumn in the woods of Quinto Real. A magical moment, the stags seek does to mate and preserve the species. During this period, the stags suffer incredible stress, wandering around all night long without worrying practically at all about eating. They begin their thunderous bellowing and wailing at twilight, beckoning the does and marking their territories. At dawn, the deer gather in clearings, where the stags wage war under the attentive gaze of the does. A winner, who shall mate with all of the does, emerges from the fight.

The loser, weak and humiliated, leaves the area to return once recovered to try to win the post.
The name of Quinto Real (Royal Fifth) dates from the Middle Ages: in the XIII century, the Kings of Navarre received the fifth part for use as pastures and a source of timber.

The Valley of Baztan can be reached from Quinto Real via the pass of Artesiaga, as can Alduides via Urkiaga.

Sorogain (Valley of Erro) is a wonderful place to relax, take gentle walks or climb a mountain without too much difficulty. It is a magnificent corner where time would seem to have stopped: a broad, green carpet surrounded by beech trees, oak trees and mountainside. In the background and in all its majesty, Mount Adi appears to keep eternal watch over a paradise where leafy woods, fields and river come together to form an unforgettable landscape. Sorogain is the common-land home to animals from the Valleys of Erro and Baigorri, and festivals are held to celebrate the "marking" of the livestock. Several dolmen sites are scattered over the pastures to remind you of the area’s pastoral prehistory. Sorogain has a recreational area set in surroundings of great beauty, complete with tables, benches and stone barbecues.
