Slovenia offers tourists a wide variety of landscapes: Alpine in the northwest, Mediterranean in the southwest, Pannonian in the northeast, and Dinaric in the southeast. They roughly correspond to the traditional regions of Slovenia, based on the former four Habsburg crown lands (Carniola, Carinthia, Styria, and the Littoral). Each offers its own natural, geographic, architectural, and cultural features. Slovenia has mountains, meadows, lakes, caves, and the sea, making it an attractive destination in Europe.
The nation's capital, Ljubljana, has many important Baroque and Art Nouveau buildings, with several important works of the native born architect Jože Plečnik. Other attractions include the Julian Alps with picturesque Lake Bled and the Soča Valley, as well as the nation's highest peak, Mount Triglav. Perhaps even more famous is Slovenia's karst named after the Karst Plateau in the Slovenian Littoral. More than 28 million visitors have visited Postojna Cave, while a 15-minute ride from it are Škocjan Caves, a UNESCO World Heritage Site. Several other caves are open to public, including the Vilenica Cave.
