Transylvania is the largest region of Romania and probably the best known one. When you visit Transylvania you dive into a mix of cultures, nature and history. Transylvania is a diverse region: it is worth trying to observe the differences that exist within the region, both culturally and naturally. This region is a place with abundant history and multicultural convergence. All over Transylvania the cohabitation of Romanians, Hungarians, Saxons and Roma is the leading theme. Transylvania is rich in myth and misty medieval sites: there about 100 castles and fortresses and about 70 fortified churches. Romania's greatest and best preserved castles and fortresses are to be found here. But for the more curious traveler, there are many small villages with old houses and fortified churches. As Transylvania is circled by the Carpathian mountains there are a lot of mountain forests and hiking or climbing possibilities. All over the Carpathians there are great national parks. In the center of Transylvania there are green hills and rivers. Most big cities are very western Europe like, and the infrastructure is generally good, making it easy for travelers.
