They are one of the richest ecosystems of Europe, the best groves of Navarra and
possibly the most important of the whole valley of the river Ebro; an ideal
place for walking. Its 25 kilometres length invites you to get lost, and the
warm land forests are oasis of cool vegetation, tender and green. The
nightingale, the wryneck, the royal woodpecker, the cuckoo, the booted eagle,
the pied wagtails and an endless number of different sorts of birds will liven
up the way from the bushes and shrubs of the forest and among the reed beds.
