Massif des Arbailles walks

Seen from a distance, the silhouette of Behorleguy gives the impression of an enormous peak and of being difficult. In fact, this is misleading and when you arrive on its southern face, it has a rather rounded shape. It is an enormous limestone fold that heralds the Arbailles massif. Magnificent view from the summit with the Pic des Escaliers to the south and the Arbailles massif to the north.. At the Col d'Aphanize, you can see a vertical chasm 500 m deep, one of the deepest chimneys in the world.

This peaceful route through the woods offers walkers the chance to discover a rich natural heritage. The flora and fauna along the route are particularly rich, with white-backed woodpeckers, Alpine longhorn beetles, beautiful specimens of beech trees and a wide variety of ferns. In addition to these natural curiosities, information panels on Basque mythology are dotted along the route. Finally, the arrival at the source of the Bidouze and its resurgence in a porch carved into the cliff will delight young and old alike.

Located between the provinces of Basse-Navarre and Soule, the secret Arbailles massif offers many attractions for curious hikers. This limestone massif is renowned for its karstic relief, which is ideal for caving. Located in the northern part of the massif, the Beltxu route offers beautiful views and a challenging and varied hike. The view stretches far into the distance and is well worth the extra effort.
