About the name Cuernavaca

The pre-hispanic name of what is now Cuernavaca was the nahuatl word Cuauhnahuac which meaning is aproximately "near the forest". The spaniards were unable to pronounce the name Cuauhnahuac and they started to call the place "Cuernavaca" which is a strange word composed by cuerno (horn) and vaca (cow) which has nothing to do with the original meaning.

Most establishments accept Visa, Mastercard, Carte Bleue, and other main credit cards, as well as recognized travellers cheques in American dollars and even dollars in cash. The automated teller machines/debit machines/guichet automatique (in Spanish, Cajero Automatico) accept all of the above-mentioned cards in order to get instant cash. The exchange rate is good at these machines.

Safe Food and Water

It is not advisable that you buy food from street vendors, as hygiene is not necessarily the best. Make sure that the water you drink is bottled. You can drink water from the tap only if you boil it for more than 15 minutes (due to the altitude, water boils at a lower temperature). When you are in restaurants, it is advisable not to ask for ice in your drinks, unless it is the "official" ice which has been purified. These cubes have a hole through the middle. In fancier restaurants you can safely assume that the water and the ice are purified.
