For those who seek contact with nature and wildlife, the Bioparque Estrella, Cola de Caballo, a crystal clear waterfall which falls from 25 metres above, and the Parque la Huasteca, famous for its mountainous terrain. Culture and the arts add to the quality of life here. Visit the Museo de Arte Contemporáneo (MARCO), Museo de Historia Mexicana and the Centro Cultural Alfa with a mega Omnimax screen. For those seeking shopping as a pleasure, there are expansive commercial centres offering products and services, which cater to every whim.
