Sochi's subtropical climate means that greenery flourishes in the city and the wilderness surrounding Sochi is full of wildlife. This climate - along with beaches and the potential for skiing in the mountains - attracts droves of vacationing Russians who either fly in or make the trip by train. Lots of family attractions, restaurants, bars, theaters, and more fill visitors' hours when they aren't at the beach. Sanitariums, which offer spa and medical services, are also popular for those who want an all-inclusive program of relaxation. Travel to Sochi is also enjoyed by Russia's prime minister, Vladimir Putin, who is given credit for securing Sochi's bid to host the 2014 Winter Olympics.
