The image depicts the entrance to a rock-hewn tunnel, characteristic of a levada, located in the vicinity of Ribeira Brava, Portugal. A single individual, seen from behind, is walking away from the camera and into the dark interior of the tunnel. The person wears a dark long-sleeved top, light-colored shorts, blue athletic shoes, and carries a light olive-green backpack. The tunnel entrance features rough, natural rock walls and ceiling, with patches of green moss and small ferns growing on the sunlit surfaces. Sunlight strongly illuminates the foreground, casting distinct shadows, including that of the photographer, across the path and water. To the left of the frame, a concrete path leads into the tunnel. To the right of this path, a clear, shallow stream of water flows through a man-made channel. The water's surface shows ripples and reflections, and the channel bottom reveals submerged green moss, reddish-orange discoloration, and some organic debris. In the immediate foreground on the right, the water channel is covered by a metal grate composed of parallel bars. Concrete steps descend towards the start of the path and the water channel, indicating a lower elevation for accessing the tunnel. The interior of the tunnel beyond the entrance recedes into profound darkness.
