Source of Hubelj - Sinji vrh (via Otliško okno)

Access to starting point:
We drive on the expressway from Razdrto towards Nova Gorica or vice versa and take the Ajdovščina exit. Then at the intersection (first traffic light) we continue straight in the direction of Cola and Idrija. At the second traffic light we turn right, again in the direction of Cola, and follow the road for only a few dozen meters to the spot where we cross the Hubelj river. Immediately after the bridge we turn left in the direction of the Hubelj spring (by the road we notice tourist signs). We follow this road to the parking lot at the Hubelj spring.

Path description:
Near the parking lot we notice the start of the path to Otliško okno. The path first ascends the stairs and then enters the forest, where it moderately ascends for some time. The path then slightly descends and takes us to a panoramic slope from where a nice view opens towards the slopes of Čavna. The path then enters the forest and quickly brings us to a birdhouse next to which we notice a thermometer. Just a few meters ahead there is a pleasant bench by the path. Ahead the path starts to ascend and takes us past the spot where the story of the origin of Otliško okno is written. The path then becomes steeper and steeper and soon brings us to rocky slopes. Step by step the path becomes more panoramic and varied. A little higher the path brings us below Otliško okno, which we already see on the right side. Just a little further we notice the sign for Malo Otliško okno. Malo okno is only 10 m from the path and is worth seeing. Ahead the path turns into an indistinct gully in the middle of which we notice a nativity scene at Christmas time. At the top of the gully we reach a chapel with a logbook and stamp. Here we continue right towards the window, which is another five minutes away. Just before the window a path branches off to the left to the stone snail, which is only a good minute from the path. From the snail we return to the path we left and in a few dozen steps reach the information boards at Otliško okno. From the boards we can descend to the window from which a nice view opens onto Vipava valley.
From the window we continue along the path towards Sinji vrh. Ahead the path quickly emerges from the forest and takes us to panoramic slopes along which we ascend by the edge of the cliffs in the southeast direction. After about 10 minutes of walking from the window the path forks into two parts. At the spot where the grazing fence makes a sharp left turn we leave the wide path and head right onto a worse but marked path that brings us to the summit after five minutes of ascent (the path is marked but the blazes are rare and poorly visible).
From the summit the path descends to a small saddle where we rejoin the path that bypasses Navrše. Ahead the path crosses a strip of forest and a bit further brings us to a pleasant viewpoint where the path via Stara baba joins. Here at the electricity poles the blazes for Sinji vrh direct us left onto a cart track that first slightly ascends and then gradually descends. When the path ascends again we step onto the road where we continue left uphill (to the right the road ends at the last house in the village). After a few minutes of walking along the road we reach an intersection where we continue right and then after a few meters right again. The road, which ahead ascends a bit more steeply, takes us higher to another intersection where we again continue right. This is followed by another 700 m of walking along the road to the Sinji vrh pension. Here the road ends and we continue along an unmarked path to Sinji vrh, which we reach in three minutes. Orientation in the last section is not difficult.
