Source of Hubelj - Sinji vrh (via Otliško okno)

Access to starting point:
We drive on the highway from Razdrto towards Nova Gorica or vice versa and go to the exit Ajdovščina. Then at the crossroad (first traffic light) we continue straight in the direction of Col and Idrija. At the second traffic light we turn right, again in the direction of Col and we follow the road only few ten meters to the spot, where we cross river Hubelj. And immediately after the bridge we turn left in the direction of source of Hubelj (by the road we notice tourist signs). We follow this road to the parking lot at the source of Hubelj.

Path description:
Near the parking lot, we notice the beginning of the path towards the window Otliško okno. The path at first ascends on stairs and then goes into the forest, where it is for some time moderately ascending. The path then slightly descends and brings us on a panoramic slope from where a nice view opens up towards the slopes of Čaven. The path then goes into the forest and it quickly brings us to a bird house by which we notice a thermometer. And only few meters ahead by the path pleasant bench. Further, the path starts ascending and leads us past the spot, where the story is written about the origin of Otliško okno. And the path is then becoming steeper and steeper and soon brings us on rocky slopes. And the path is with every step becoming more and more panoramic and diverse. A little higher, the path brings us below window Otliško okno, which we already see on the right side. And only a little ahead we notice a sign for Malo Otliško okno. Malo okno (little window) is from the path distant only 10 meters and is worth seeing. The path ahead passes into an indistinct gully in the middle of which in Christmas time we notice cribs. On top of the gully, we come to the chapel where there are an inscription box and a stamp. Here we continue right in the direction of the window, to which we have five minutes of walking. Only a little before the window path branches off to the left towards stone snail, which is from the path distant only a good minute. From the snail, we return back on the path which we left and in few ten strides we come to information boards at window Otliško okno. From the signposts, we can descend to the window from which a nice view opens up on Vipava valley.
From the window we continue on a path in the direction of Sinji vrh. The path ahead quickly comes out of the forest and it brings us on panoramic slopes on which we are by the edge of the cliffs ascending in the southeastern direction. After approximately 10 minutes of walking from the window the path splits into two parts. At the spot, where grazing fence makes a sharp left turn we leave a wide path and we go right on a bad but marked path, which after five minute of ascent brings us to the summit (path is marked, but blazes are rare and poorly visible).
From the top, the path descends to a small saddle, where we again join the path which bypasses Navrše. The path ahead crosses a lane of a forest and a little further brings us to a pleasant viewpoint, where it joins the path over Stara baba. Here at power line poles blazes for Sinji vrh point us to the left on a cart track which at first slightly ascends and then it is gradually descending. When the path ascends we again step on the road, where we continue left upwards (to the right, the road at the last house in the village ends). After few minutes walk and on the road we come to a crossroad, where we continue right and then after few meters once again right. The road which is further a little steeper ascending higher brings us to another crossroad, where we again continue right. Next follows 700 more meters of walking on the road to boarding house Sinji vrh. Here the road ends and we continue on an unmarked path towards Sinji vrh, which we reach after three minutes. Orientation in the last part isn't difficult.
