We walked only along the gorge (photos taken from the drone), but you can see it from above, using the upper hiking trails. It is also the most popular climbing place in Romania.
If you have car and want to spend the night somewhere in the area, we recommend the Pensiunea Cheile Apusenilor (booking.com). Located in the middle of nowhere, very interesting and unusual place. 5 minutes to the canyon by car. Here is a view from the window.
The gorge is to the left on the map
Getting there: Close entrance N 46 33.689 E 23 41.467, far entrance N 46 34.268 E 23 40.020. 40 km from Cluj-Napoca. The nearest railway station is Cimpia Turzii, 25 km from away. From there only by taxi. Turda is located at the intersection of the main roads, it's also easy to get here by bus (http://www.autogari.ro/).
