Peña Unzué (990 m) is probably the most emblematic and beautiful mountain in the whole of the Zona Media, visible from a large part of the region. Although it is the lowest peak in the Sierra de Aláiz, it is easily identifiable by its large limestone walls and its almost pyramidal silhouette, making it one of the best-known and most frequented trekking ascents in Navarre.
The ascent to Peña Unzué is relatively short but hard, with very steep ramps in some sections, so a minimum level of fitness is required. It starts crossing the pretty village of Unzué and continues steadily uphill, first on a road and then on a narrow path through holm oaks, boxwoods and junipers. The path first ascends very directly towards the Peña, but at the top it becomes smoother and ends up bordering the walls on the right, to end up accessing the summit from the east.
At the summit you will enjoy spectacular views in all directions. In addition, at the top there was a castle of which there are references from the year 1300 and of which only the remains of a tower remain, reinforced recently.
