Mexico ’s national currency is the Peso.  Though some merchants both along the border with the United States and in interior destinations popular with tourists from the USA will accept the United States Dollar and/or the Canadian Dollar or the Euro, you should plan to exchange your home-country for Pesos before you arrive in Mexico or at banks, currency exchanges or automatic teller machines as soon as you arrive.  See the Banks and Money section of “Know Before You Go” for a description of the forms of money used in Mexico.
