The Arbaiun Gorge is a spectacular natural formation located in the Navarrese pre-Pyrenees, near the village of Izalzu. This deep, narrow canyon is carved by the Salazar River, which over millennia has eroded the limestone rock, creating dramatic cliffs that rise steeply on either side.

The gorge is part of the Arbaiun-Salazar Valley, a protected natural area. Visitors can reach the site from the town of Aoiz, following well-marked roads and trails that lead to various viewpoints. There are also designated hiking paths that allow visitors to explore the gorge’s lush surroundings, offering panoramic views of the river, cliffs, and forested slopes.

The best time to visit is during spring and autumn, when the landscape is at its most vibrant. The region’s mild climate and diverse flora and fauna make it ideal for outdoor activities such as hiking, birdwatching, and photography. The Arbaiun Gorge is a must-visit for those interested in natural landscapes and geology, providing an immersive experience in one of the Basque Country’s most scenic locations.
