Since the mines opened in 1886, Sungai Lembing attracted wave after wave of Chinese migrants from southern China, all in search of a better future. My grandfather, born in 1882, was among them. He arrived as a young man, most likely in the early 1900s. Driven by the hardships back home, he left behind his young wife and children in China and journeyed thousands of miles to what was then known as a land of opportunity. Like many others, he likely intended to return home once he had saved enough money. However, for reasons unknown, he eventually left Sungai Lembing and moved to North Borneo. There, he married a local native woman, started a new family, and never returned to China.
At its peak, the Sungai Lembing underground mine was considered one of the largest and deepest tin mines in the world. Its tunnel network stretched an astonishing 322 km, reaching depths of up to 700 m - far deeper than the height of the iconic Petronas Twin Towers, which stand at 450 meters.
Mining operations at Sungai Lembing finally ceased in 1987, when the cost of extracting tin at such depths became no longer economically viable.
Today, the Pahang state government has taken over the site and transformed it into a heritage tourism destination. The tunnels that are now open to tourists are part of the original mining network, though they have been carefully refurbished to ensure visitor safety. Notable upgrades include concrete guniting along the tunnel walls and soil nailing to stabilize the structure and prevent potential collapses.
