What to Know About Onís

Key Facts

Onís is a municipality (concejo) located in the Oriente region of the Principality of Asturias, Spain. Situated in the eastern part of Asturias, Onís lies within the Picos de Europa mountain range, specifically in the area known as the Picos de Europa National Park, which it partially occupies. The municipality covers an area of approximately 75.42 square kilometers and has a population of around 750 residents, making it one of the less densely populated areas in Asturias. Onís is administratively divided into several parishes (parroquias), including Benia de Onís, Avín, and Gamonéu, each contributing to the municipality's rural and mountainous character. The landscape is dominated by limestone mountains, deep valleys, and traditional pastoral activities, with cheese production, particularly the renowned Gamonéu cheese, being a key economic and cultural element. Historically, the area has been shaped by its isolation and the challenges of mountain living, preserving many traditional customs and architectural styles. For those seeking postal code information for its parishes and villages, Onís offers a glimpse into the authentic rural life of the Asturian mountains.
