Precipitous Turda Gorge (Cheile Turzii) lies 8km west of town (as the crow flies), and it makes a stunning, if leg-stiffening, half-day hike. The canyon is nearly 3km long, with 300m-high walls sculpted in weathered limestone. Walking the gorge’s length takes roughly 1½ hours each way. To get there, take a bus from Turda to the centre of Cheia (4 lei, 30 minutes). From there it’s a straightforward roadside 5km hike to the gorge (follow the ‘cheile turzii’ signs).
