An inflatable boat with two occupants is sailing on the calm waters of Koprinka Reservoir, near the city of Koprinka, Bulgaria. The boat, white with blue accents, has a canopy providing shade. The occupants, one of whom appears to be steering, are looking forward. The reservoir is surrounded by a dense line of trees on the left bank, and rolling hills with scattered trees on the right bank. In the background, a prominent hill is topped with a small structure, possibly a monument or lookout tower, and a faint contrail stretches across the pale sky. The sun is low in the sky, casting a warm light and creating a rippling reflection on the water's surface. In the foreground, a branch with bright green and yellow leaves extends into the frame from the right, partially obscuring the water.
