Peña Bajenza, Mountain summit in Islallana, Nalda, Spain

Peña Bajenza is a 941-meter summit featuring reddish rock formations shaped by natural erosion. The peak overlooks the Iregua River valley and surrounding settlements in the landscape.

The summit cross commemorates, according to local legend, a monk who jumped to his death from the top of the rock formation. Each year on May 3 the Romería de la Cruz brings families and children up to that cross, the higher of two crosses on the mountain; the lower one stands at the start of the route, 475 metres above sea level.

On May 3rd each year, local families climb to the summit as part of a pilgrimage tradition. This gathering reflects how the mountain remains woven into the community's yearly rhythm and spiritual practices.

Multiple trails lead to the summit from different starting points in the surrounding area. Most visitors should expect a moderate climb that takes between two to three hours depending on the route chosen.

The summit cross at 941 metres marks the end of the Romería de la Cruz each 3 May; local legend says it commemorates a monk who jumped to his death from the top of the rock. A lower cross stands at the start of the route, 475 metres above sea level.
