When the sun goes down, South America rises. The nightlife options here are as varied and as enticing as the daytime attractions, albeit perhaps with just a bit more sizzle. Night owls can choose to unwind with a relaxed vibe, or stoke the flames of after-dark adventure. Festivals and ferias (“feiras,” in Brazil) abound, along with, of course, less formal agendas. Regardless, given the social spirit and hospitable nature of the South American people, you’ll never lack for company.
