Parque Fundidora is Monterrey's most distinctive public space — a large urban park built on the site of the city's 19th-century iron and steel works. The rusting blast furnaces and industrial structures have been preserved and are now framed by walking trails, a canal, cycling paths, and lawns. Several museums are scattered across the grounds, including the Museo del Acero (the steel museum), which occupies a converted blast furnace.
The park is large enough for a half-day visit. It is popular with cyclists and families at weekends, and hosts concerts and events throughout the year. Entry to the park is free; the museums charge separately. The best time to visit is morning, before the sun gets high.
