Jardim Botânico, Brazil

This wealthy enclave of Rio de Janeiro is home to 77,767 residents, many of them celebrities and executives. The neighborhood's large detached houses and lack of nearby favelas are indeed rarities in the densely packed South Zone. However, living here comes with a persistent headache: the bureaucracy required to navigate the city's massive Botanical Garden and winding roads up into the Tijuca Forest. Jardim Botânico may appeal to the upper-crust seeking a posh, private oasis, but it's hardly the vibrant, carefree lifestyle that draws many to Rio.
