The image shows a narrow tunnel with a stone wall on one side and a concrete floor on the other. The tunnel appears to be underground and is surrounded by greenery. The walls of the tunnel are made up of small, irregularly shaped stones, creating a textured pattern. The floor is made of concrete and there is a small amount of dirt or debris scattered around the tunnel. The image is taken from a low angle, looking up at the tunnel from the left side. The overall mood of the image is peaceful and serene.
