The economy of Beasain is driven by a combination of industrial activity and agriculture. It is particularly well-known for its railway equipment industry, with companies like CAF (Construcciones y Auxiliar de Ferrocarriles) playing a central role in the local economy. CAF is one of the leading manufacturers of trains and railway equipment in Europe, providing jobs and economic stability to the town and surrounding areas.
Aside from industry, agriculture and livestock farming are also important to the local economy. The surrounding region is rich in natural resources, and traditional Basque farming practices continue to thrive. Local products such as cheese, cider, and meats are renowned for their quality, and there is a growing emphasis on sustainable and organic production methods.
Beasain also benefits from its proximity to larger economic centers in Gipuzkoa, such as San Sebastián, which enhances its connectivity and economic opportunities. While tourism is not a primary economic driver, the town is increasingly attracting visitors interested in its natural beauty and Basque cultural experiences.
