Lima. After Cairo, this sprawling metropolis is the second-driest world capital, rising above a long coastline of crumbling cliffs. To enjoy it, climb on the wave of chaos that spans high-rise condos built alongside pre-Columbian temples and fast Pacific breakers rolling toward noisy traffic snarl-ups. Think one part southern Cali doused with a heavy dose of America Latina. But Lima is also sophisticated, with a civilization that dates back millennia.
