The proposal is to start in Zali Log village, because at the end of the tour you almost must visit the inn there - they have the best trouts. If so...
... from Zali Log you bike 2.1 km by the main road westwards, hardly gaining any altitude. There the asphalted side road deters right, steeply uphills (inscription: Ravne, Torka).
The next 5.3 km are only steep uphills. The road is mainly asphalted, in the middle part there's still a stretch of macadam (2019). At first the slopes are S oriented, but shady due to forrest, then the road goes by the NW slopes of Lajtnik hill. From below Ravne hamlet till the highest point above the hamlet of Torka, the road is sunny and panoramic. From the crossroads till here there's always almost no traffic.
In Ravne the horizontal part starts and the road turns into macadam. After 1.2 km we reach Zabrdo hamlet and after another 1.6 km the biggest houses in Zgornje Danje hamlet.
After Zgornje Danje another small ascent awaits us, when we are around the mountain ridge, the road again goes through the woods and is not any more panoramic. After 2.7 km from Danje we reach the main road above Sorica village.
By the main road we do one more turn (650 m) and reach another crossroads, where we need to decide. The road left goes directly down into Sorica village, the road straight crosses further to the Petrovo Brdo road pass.
a. Petrovo brdo variant: We simply continue crossing the grassy slopes above Sorica village. The road goes a bit up and down, after 4.2 km we reach the Petrovo Brdo road pass.
On Petrovo Brdo road pass we turn sharply left, starting the descent in the direction to Škofja Loka (plates). After the first few turns the road becomes more straight, all the time following Sora river bed. After 8.1 km of quick descent we reach the crossroads, where from the left the direct road from Sorica village joins.
b. Sorica village direct descent: You descend quickly by the main road to Sorica village (visit there perhaps the house of Grohar painter and his monument), and then continue more and more steeply down into the valley of Sora. After 5.4 km you reach the valley and the road, joining from Petrovo Brdo from the right. So, variant b is some 7 km shorter than variant a.
Then you continue down by the Sora valley. After 1.5 km you close the loop, after another 2.1 km you reach the village of Zali Log.
Of course, you can skip this 2.1 km in the beginning and the end of the tour and start biking from the crossroads of Ravne/Torka road.
