The educational path runs through the valley of Rakov Škocjan located between the Planina and Cerknica fields. The disappearing river Rak flows through Rakov Škocjan. This river is the forerunner of the river Ljubljanica. This karst valley was created when the ceiling of underground halls and caves collapsed. Only the Small Natural Bridge and the Great Natural Bridge remained from the former arch. Rakov Škocjan is 2.5 km long, and it is a natural pearl of the Notranjska region. Since 1949, it has been protected as a regional park.
