This location is part of the broader historical and cultural region of Navarra, specifically within the Alto Bidasoa subregion, which is known for its lush, green landscapes, traditional Basque culture, and proximity to the French border. The area around Oiz is characterized by scattered rural settlements, agricultural activity, and natural beauty, with the mountain itself offering popular hiking trails and panoramic views. While precise population figures for the immediate Oiz area are limited due to its small, dispersed nature, it contributes to the broader Alto Bidasoa population, which is part of Navarra's northern mountainous zone.
