Ayer Itam Dam, located about 7.6 km from George Town on the slopes below Penang Hill, is Penang’s oldest and once-largest dam, built between 1958 and 1962 with a capacity of 2.16 billion litres. It supplies water to nearby areas like Ayer Itam and Paya Terubong and also offers a peaceful 2.8 km walking trail with scenic views of the city and surrounding hills. Interestingly, it was the first earth dam in the world designed using electronic computers for structural analysis—a pioneering move at the time. Today, it remains a popular spot for hikers, birdwatchers, and nature lovers alike.
