Beware of Naples’s un-air-conditioned cabs.

In the hot summer, hopping into a cab outside Naples’s Stazione Centrale rail station can lead to a total meltdown, thanks to the city’s constant traffic jams and global-warming temperatures. Solution? Head for the city’s trams, trains, and buses, all of which—miracle of miracles—are nicely air-conditioned. See more travel tips in our Naples Travel Guide.
