Guarulhos is a city in São Paulo, located in the metropolitan area of the city of São Paulo. It is mostly known for its international airport, the most important of South America and the main gateway to São Paulo. Indeed, as an industrial city, Guarulhos has not much to offer to a visitor, although there are remarkable exceptions, like the Cabuçu center of Parque Estadual da Cantareira, one of the most beautiful nature spots of the São Paulo metropolitan area.
