From Cluj-Napoca (airport available) take E60 road to Turda (around 25 km). From Turda there are two possibilities:
Take DN75 road to Campeni. 7 km after passing Mihai Viteazu turn right towards Cheia village. Pass through the village and continue until you’ll see the gorge (east entrance).
Take secondary road and drive towards Petreștii de Jos village. A short walk from the village will take you to the west entrance of Turzii Gorge.
