These caves on Chihuahua’s northeast edge boast impressive stalagmites, stalactites and rock formations, making the one-hour, 17- chamber underground journey fun, especially for kids. To get here take either a taxi (M$80) or a ‘Nombre de Dios Ojo’ bus (M$6) from outside Posada Tierra Blanca on Niños Héroes. Ask the driver where to get off.
