The first time I was there I was taking a 3 day trip. This wasn't in our trip and when I saw it on my way to Alba Iulia from the highway nearby I found the nearest exit and navigated visually. You can imagine I couldn't get there due to the highway always being in the way of my route. Eventually I started Google Maps and it gave us a quick route. Don't rely on Google Maps since he think there is a road UNDER the highway, which is not. We got to a ditch and scared a couple of lovers in an old car.
Then we abandoned it and returned at the end of the 3 days, the Waze GPS took us under a highway bridge but then it took us to the edge of the forest. Sadly the field nearby was freshly plowed so we had to follow the tree line forest road which took us through 2 irrigation ditches. Hit everything under the car every single time, feared water coming in and even managed to get suspended once. Finally used all of my offroad technique ( I don't drive an offroader :) ) and managed to get there in the big parking lot, next to the military shooting range. Totally worth it :)

The rest is like you said. Steep incline and descended through the forest.
