Carnaval de Las Piedras in Las Piedras
Las Piedras is Uruguay's third most populous city, a major hub within the Canelones department just north of Montevideo, and while the country's carnival season is well documented nationally, no source specifically detailing a distinct Carnaval de Las Piedras program, route or queen tradition was found.
Available sources confirm a great deal about Las Piedras as a city, but not a specific, documented Carnaval de Las Piedras program, so this entry is written to reflect that honestly rather than filling the gap with invented parade details.
