Vladayska River

The river takes its source at an altitude of 2,245 m from the northwestern slopes of Cherni Vrah (2,290 m), the highest summit of the Vitosha mountain range. It flows northwest through the Torfeno Branishte nature reserve, then submerges beneath the stone run of Zlatnite Mostove, and descends to the village of Vladaya in a deep, steep and forested valley.

In the village the river bends in direction northeast, runs through the Vladaya Saddle that separates Vitosha from the Lyulin mountain range, and then enters the Sofia Valley and the outskirts of the city of Sofia. There, it runs through the neighbourhoods of Knyazhevo, Karpuzitsa and Ovcha Kupel, reaching the Serdika industrial zone.
