IPOH: Caving enthusiasts have found a cave tunnel believed to be over a century old and used by people then to traverse between villages in Simpang Pulai. Perak Natural Heritage Geopark Tour Guides Association chairman Mohd Fadly Md Noor said the tunnel was about 400m long and was discovered at Gunung Lanno in October. Mohd Fadly said there was even a flight of steps, believed to be man-made, inside the tunnel. “All of these are based on our observations and we hope other parties can do a proper study on it. “We just want to let people know what we have found,” he told reporters when met near the tunnel on Saturday.
