The image displays the entrance to a pedestrian tunnel carved into a natural rock formation in Kamenovo, Montenegro. The tunnel entrance is characterized by a white, concrete, arched facade. Dark script, possibly "T. C. O.", is present on the upper inner curve of the arch. On the right inner wall of the archway, dark blue text reading "BACABME" and "10M" is visible. Faint red markings are discernible on the left inner wall. The tunnel interior is dark, signifying a lack of illumination within. A narrow, dark grey paved pathway leads directly into the tunnel. The surrounding environment consists of a steep, rugged rock face, primarily composed of reddish-brown, orange, and grey rock strata with visible erosion. Green Mediterranean vegetation, including trees and shrubs, grows sparsely on the upper sections and edges of the rock face. Dry, thorny branches partially overhang the scene from the upper left. The sky overhead is clear and deep blue. The ground immediately adjacent to the pathway contains loose earth, dry vegetation, and minor scattered debris. No individuals or animate subjects are present. The scene is illuminated by direct sunlight, casting distinct shadows.
