Vrachanski Balkan national park is a natural canyon where Leva river cuts trough the rugged landscape. Below the drone you can see the Vratsata gorge, to the north is the town of Vratsa and to the south is the village of Zgorigrad. It's quite rare to have all of these in a single shot due to the multiple ridges and topography of the terrain.
