"Mexico City is often depicted—and not incorrectly—as a capital city teeming with buildings, people, and cars. It also, though, has a surprising number of green spaces and parks, the most expansive of which is Bosque de Chapultepec, right on the edge of Polanco. It's easy to while away a good bit of time in Chapultepec; the park has a zoo, a lake where you can rent pedal boats, street performers making music and magic, and the Castillo de Chapultepec—Chapultepec Castle—which houses the National History Museum. If you're hungry, you'll find plenty of vendors peddling everything from roasted corn on the cob to cotton candy."
