Fruška Gora National Park

Serbia's oldest national park, Fruška Gora is an 80km stretch of rolling hills where cloistered life has endured since monasteries were built between the 15th and 18th centuries to safeguard Serbian culture from the Turks. Of the 35 original monasteries, 16 remain and they're open to visitors. Fruška Gora is also famous for its small but select wineries; grapes were first planted here in AD 3 by the Romans.
