Spotlight on Russia visits Sochi - the resort capital of Russia.
The city of Sochi is a popular Russian holiday resort on the Black Sea coast. It is about 1,500 miles south of Moscow. The city is famous for its warm weather, beautiful landscapes, golden beaches and health spas.
Every summer, more than 1.5 million visitors from Russia and abroad spend their holidays there. People travel to Sochi by both air and sea. It has got an international airport with flights to most major Russian cities, as well as Europe. Its port has a direct sea link with Turkey, Greece, Georgia and Ukraine. Most tourists visit the city in the summer, but the winter season attracts skiers to the Krasnaya Polyana resort. As well as skiing, visitors can enjoy hunting, fishing and mountain climbing. There are also lots of festivals in Sochi and every year in June there is the international film festival. In the evening, Sochi is alive with colourful street cafes and restaurants where you can eat delicious food at reasonable prices.
