Walk down Paseo de la Reforma - Starting at Chapultepec Park, take a long stroll down this wide tree-lined boulevard, inspired by the Champs Elysees in Paris. The boulevard is punctuated with different monuments, starting with a large fountain, Fuente de Diana Cazadora. The next monument is the Monumento a la Independencia (El Angel), a tall column with an angel on top. The Monumento a Cuauhtemoc commemorates the last Aztec emperor. The last monument, Monumento a Cristobal Colon, is in honor of Christopher Columbus.

Tip: The Mexico City subway is a great way to get around the city. The Metro is fast, modern and some stations have bits of Aztec ruins. When you take taxis in Mexico City, only take ones from marked taxi stands (or have your hotel call a taxi). Don't hail any old taxi off the street.
