I recommend from Grahovo. The path is somewhat "straight up". Follow the path past the last houses to the right above the village stream - past the "bunker". The path is traceable - some fallen trees in between. There the path gets a bit lost. I continued to the right (I think it would be correct to look for the path to the left behind the fallen trees), so I reached the ridge where you can see the village of Koritnica. No problem - there are also small paths and at about 1000 m you reach the path from Grahovo. Follow the ridge to the summit. I think you'll be happy not only with the nice view but also with the orchids. Then you can descend to Temljinska planina, then to Temljine. From there to the starting point along a nice path in less than an hour.
