The Predjama castle is the most prominent mark of this stage. Today, it houses museum collections and has well preserved period furniture. On the northern fringe of the basin we find the last inhabited settlements before the terrain rises to the spacious Hrušica forests. Like Nanos, Hrušica belongs to the High Karst, a chain of high Karstic plateaux covered by Dinaric fir and beech. Important routes from the Friulian lowlands to the Danubian area once ran across Hrušica. Here ran the Roman main road from Aquilea via the Vipava valley to Emona, present-day Ljubljana.

Because of the ever-present threat of incursions by barbarians from the east, the Romans built an impressive chain of fortifications in this area. The remains of the road and ruins of walls can still be seen today. From Hrušica, a labyrinthine forest path leads past several sinkholes through the formidable fir and beech forest. We cross Javornik, from where there is a view of the Alps, and descend to the Črni vrh plateau.

Author’s recommendation

Check how and where roman fortifications were set up, so it will be easier for you to spot and appreciate it.

Turn-by-turn directions

The stage begins at the Linden tree in the village of Predjama. Walk to the upper parking place then walk right along the tarmac road past the houses. After about 400 m, there will be a stone wall next to the road. Climb up the footpath that turns left. The path ends after about 50 m and gives way to a very steep macadam road, where you will turn left. Walk for another 50 m to the top of the slope, where the road makes a sharp right turn towards a house. Take the footpath into the forest.

The road is quite flat at first then begins to climb gently. When you reach the macadam road, turn right and walk past the clearing to the tarmac road. 15 minutes. Walk up the road for about 500 m until the tarmac gives way to macadam at the crossroads. Continue walking straight ahead. The road leads runs through slightly inclining Karstic terrain. Keep walking north, passing several crossroads and macadam forest roads on the way. Just before you reach the hamlet of Hrušica, turn to the northeast.

There is a crossroads with a direction panel to the left indicating the way to Javornik. Make sure to continue straight ahead along the main road to the Stara Pošta inn at Podkraj. 1h 15 min. Turn left here onto the macadam road and bypass the Svisli peak. Go right and walk along the main road down to the crossroads, then turn left onto a side road. The tarmac ends after about 50 m. Turn right here and walk along the macadam road. The walk to the crossroads takes 1h. There is a bench next to the road where you can take a rest. Walk straight ahead up the road climbing a slope overlooking a spacious meadow. You will be able to see the Gulf of Trieste in the distance. After a 10-minute walk, there will be a clearing on a pass. Follow the road to the left and walk down to the farmstead near the road. Behind the farmstead on the right, you will see Pirnatova Koča na Javorniku (1156 m). 1h

From the hut, go north along the poor road that runs below the peak of Javornik (1,240 m). After a 20- minute descent, you will come to a well-kept macadam road. Cross to the other side of the road and follow a narrow path into the forest. Climb down through the forest to reach a large clearing and the road. Next to the road is a farmstead. The descent takes 39 minutes. Continue walking on the left side along the road and cross the clearing. On the other side of the clearing is a large quarry on the left. The road passes next the quarry and into the forest, then descends into the valley, where the forest ends and the terrain levels out. Walk along the road to the ski slopes and on to Hotel Bor.

There is a road junction at the hotel where a macadam road branches off to the left. Follow this road and past the military barracks until you reach a primary school and a tarmac road next to a sports ground. Turn left onto this road for 100 m, then turn right onto a small path and cross a small meadow to reach the main square in Črni vrh. 40 min. The hike from the hut takes 1h 15min.
