An outdoor equestrian arena in Duvanlii, Bulgaria, is observed during daylight. In the foreground, three children, viewed from behind, stand facing the arena, positioned behind a white wooden fence and a dark metal railing.

The rightmost child wears a dark green hooded jacket and light gray pants. The arena floor consists of packed sand or dirt. Several equestrian obstacles are present: a yellow and green striped pole lies diagonally on the left, supported by green stands, and a red and orange ornate jump standard is visible on the right, near which a white, red, and green striped pole lies on the ground. In the background, a person wearing a light-colored top and riding helmet is mounted on a brown horse, moving right across the arena. The horse is equipped with a saddle and bridle. A white wooden fence borders the far side of the arena, behind which a dark blue or grey building with reflective windows and a dark green container or vehicle are visible under clear, bright lighting.
