10. Carnival - Montevideo, Uruguay

Uruguayans have the longest Carnival celebration in the world, letting loose for more than 40 days every year, most vibrantly in the country's capital, Montevideo. Theaters throughout the city are assembled and locals take to the stage to present the social and political climate of the country through operas known as tablados. Taking the real spotlight, though, are two colorful parades where musicians show their skills - and African roots - through the drum-based rhythm known as candombe. PABLO PORCIUNCULA/AFP/Getty Images
