Zumárraga’s economy has historically been tied to agriculture and industry, particularly iron and steel production, which thrived during the industrialization of the Basque Country. Today, while industry remains important, the local economy has diversified. The manufacturing sector continues to play a significant role, but there has also been growth in services, including retail and tourism.
Local craftsmanship is also an essential part of the economy, with artisans producing traditional Basque goods, such as ceramics, textiles, and woodwork. These items make for excellent souvenirs and are widely available at local markets.
Tourism, while not as dominant as in nearby cities like San Sebastián, is growing steadily. The city’s scenic surroundings and cultural heritage attract a modest yet increasing number of visitors, particularly those interested in history, outdoor activities, and cultural festivals.
