The biggest resort town on what's called the "Russian Riviera," Sochi is preparing to step onto the world stage as the host of the 2014 Winter Olympics. Somewhat ironically, Sochi is really quite temperate for most of the year, with its Black Sea waters warm and swimmable well into October. The Arboretum and Riviera Park are among the city’s most popular destinations. Serving as a beautiful backdrop for Sochi are the Caucasus Mountains, home to the nearby snow skiing resort of Krasnaya Polyana.
