Vrabcha waterfall, Natural waterfall in Vrabcha, Bulgaria.

Vrabcha waterfall is a 4-metre drop on the Vrabchanska River in the Greben mountains, at about 900 m elevation where the river leaves Vrabcha village toward Tran. Just before the fall the river has cut a 20-metre rock tunnel; on its right side a karst spring feeds a fountain. Limestone walls above the short gorge hold fissures, rock niches and caves, and a picnic area stands near the fall.

The waterfall developed through slow erosion of limestone bedrock as water carved downward and sideways over millions of years. This geological process continues to shape the ravine and surrounding rock formations.

The waterfall sits where Vrabchanska River leaves Vrabcha on the road to Tran (Republic Road III-813), at about 900 m above sea level. Just before the fall the river has cut a 20-metre rock tunnel, and a karst spring with a fountain stands on its right side. A picnic spot has been built near the waterfall.

Access starts from Vrabcha village via a narrow road, then continues on a stepped path descending into the ravine. Sturdy footwear is essential since the surfaces become slippery when wet.

Just before the fall, the river has cut a twenty-metre rock tunnel; on its right side a karst spring feeds a small fountain. The limestone walls above the narrow gorge are pitted with cracks, rock niches and caves.
