I tried some access from north and then went along river to find some ways up. I had Citroen C5 and at some point I used it like Jeep. Road was very narrow between bushes and water erosion was so bad in may places that I had space to place 1/3 of the wheel on the edge of the steep erosional gulley (rest was just hanging in the air :P) and then in one point I made a picture where I had ca 1.5 m deep depression under my car :P Some places I had to place smoother rocks under the wheels to get pass from nastier places.. finally I turned around and passed very steep and broken bridge across the river.. So, I do not suggest this road to anyone :P
