The perfect complementary trip to the museum is the 50-kilometre bus trip north to the monumental pyramids of Teotihuac n which date from around the 6th century. Play safe though, go with a group, take an official taxi and, like Cinderella, plan to leave around midnight. Mexico City is a city of wonders but keep your wits about you. You're not likely to become the victim of a ritual sacrifice these days but if you flaunt them, your cameras, Rolex watch, fat wallet and credit cards might just be. On Sunday do what the Mexicans do and head to the southern suburb of Xochimilco for a well earned rest amid the floating gardens.
Locals come here to picnic, drink, sing and chat.
If you hire a boat prepare to be assaulted by a flotilla of floating traders from mariachi musicians, to souvenir and flowers sellers and food vendors. During the week the countryside around Xochimilco is much calmer and a good deal quieter but nowhere near as much fun. So there you have it - just a taster of the world's second largest city. The choice is yours.
