Railway Tunnel No. 1 of the Sierra Greenway Nature Trail. This tunnel crosses an outcrop of sandstone and marl to maintain the gradient of the railway line. This outcrop will be crossed by the following four tunnels. It is 170 meters long and is equipped with lighting; however, a flashlight is recommended. The tunnels in this railway section were constructed using shoring (supporting the excavation) with wooden beams and props, followed by formwork for the concrete slab that supports the tunnel. The tunnel entrance is finished with hewn limestone from a quarry located opposite Zaframagón.

Railway tunnel no. 2 of the Sierra Greenway Nature Trail. Located 560 meters from the previous tunnel, it is 60 meters long and has no artificial lighting, so a flashlight is recommended. This tunnel passes through an outcrop of marl and sandstone. The tunnels in this railway section were constructed using shoring (supporting the excavation) with wooden beams and props, followed by formwork for the concrete slab that supports the tunnel.

Railway Tunnel No. 5 of the Sierra Greenway Nature Trail. Located 1,030 meters from the previous tunnel, it is 200 meters long and artificially lit; however, a flashlight is recommended. This tunnel crosses a hilly terrain of Triassic clays and sandstones (180 million years old), shaped by water. These are the dominant lithologies along much of the route. Half a kilometer before the tunnel entrance, the trail crosses the Cordel del Morón cattle trail, just 500 meters from the CA-9102 road that connects the town of Olvera with the Antequera A-384 road. This cattle trail will cross again along the trail at the junction of the Guadalporcún and Guadalete rivers.
