The Petrenski Dol eco-trail follows the valley of the Petranitsa river (also called Petrenski Dol) above Gara Lakatnik, in the Iskar gorge, Svoge municipality. It is about 65 km from Sofia, roughly an hour and a half by car.
On the Iskar gorge road from Svoge, just before Gara Lakatnik, turn left towards the village of Gubislav. Soon you will see, on the right of the road, the waterfall where the Proboynitsa and Petranitsa rivers meet. There is a fountain, convenient parking and information boards by it, and the trail starts here.
The path runs almost entirely along the river, whose narrow, canyon-like valley is a chain of small waterfalls and clear pools. There are several footbridges and paths on both banks, so you can vary the walk. The eco-trail ends on a mound with a view of the village of Gara Lakatnik and the cabin above the Orlovo Gnezdo shelter.
The marked trail is about 2.6 km one way. There and back is about 5.4 km and around 2.5 hours with breaks. The climb is moderate.
The route is easy and suits children and older walkers. By the water, rocks and footbridges are slippery after rain, so wear shoes with a firm sole. The Lakatnik Rocks and Temnata Dupka cave are close by, so the walk fits easily into a day in the gorge.
