For a truly surreal experience, head for Xochimilco and hire a gondola to the Island of the Dolls, where hundreds of creepy, decomposed dolls hang from trees. An island resident fished the playthings from the canals to mollify the spirit of a girl who had drowned nearby.
The best departure point for the four-hour round trip is Cuemanco embarcadero. To get here, go to metro General Anaya and exit the station on the east side of Calzada de Tlalpan, then walk 50m north to catch a ‘Tláhuac Paradero’ pesero. Get off at the Embarcadero Cuemanco entrance.
