This is the northernmost of the seven villages that make up the Valley of Roncal. On the banks of the River Esca, Isaba stands out for the organisation of its houses into different neighbourhoods, in which you can find wood and stone buildings lining narrow, cobbled lanes. Of these buildings, the Church of San Cipriano is particularly worthy of note. The House of Memory, a modern-format museum describing the customs and traditions of Roncal, is also well worth a visit.
The Valley of Belagua, with numerous megalithic remains, such as the dolmens of Sakulo and Arrako, opens out to the north of the village. The area also has some marvellous views and landscapes.
Finally, no description of this area would be complete without mentioning the fact that it is home to Navarre’s highest mountains (Mesa de los Tres Reyes) and its deepest chasms (Chasm of San Martín).
