Romanian tourism focuses on the country's natural landscapes and its history, from medieval and Saxon villages with fortified churches in Transylvania to hot Black Sea shores and the heights of the Carpathian Mountains. Annually, more than 7 million tourists from all over the world, most of them from Western Europe and United States, spend their holiday in Romania. Many of the major touristic sites are part of World Heritage Sites, cities such as Sibiu, Sighisoara and Brasov. Romania has dramatic mountain scenery including the Carpathian Mountains and Transylvania with beautiful castles. The densely forested Carpathian Mountains area lends itself to many sporting and leisure activities such as skiing, bobsleighing, horseriding and tennis. Situated in picturesque valleys and on mountain slopes are many health and winter resorts. Since Roman times, the Romanian spas of Transylvania have been known for their miraculous healing powers. The Black Sea Coast, ideal for family holidays with 70km (43 miles) of fine white sandy beaches, boasts many resorts. Transylvania also contains the famous Bran Castle, said to be one of the original abodes of the medieval king known as Vlad the Impaler, who helped inspire Bram Stoker’s novel, Dracula.  Legend says that Bucharest, the Romanian capital, was founded by a shepherd called Bucur, whose name is recognisable in the Romanian version of the name Bucharesti.
