The Lenggong Valley in Perak, Malaysia is a sedimentary valley formed by the Perak River surrounded by the granite Bintang and Titiwangsa ranges, created over 240 million years ago by tectonic impacts.
Listed UNESCO World Heritage Site in 2012, it also holds an exceptional hominid history of 1.83 million years old, including the oldest and most complete skeleton in Southeast Asia, Perak Man, which is more than 10,000 years old. Archaeological sites in the valley include Bukit Bunuh, where evidence of ancient human activity has been discovered. A meteorite impact approximately 1.83 million years ago created suevite rocks in which stone tools such as hand axes have been discovered. In addition, there is also Gua Gunung Runtuh, where Perak man was found, as well as stone tool making workshops at Kota Tampan and Bukit Jawa, as well as prehistoric burials in karst formations. Apart from its archaeological significance, the valley is also a candidate for the designation of a UNESCO Global Geopark and an Important Bird Area due to its rich biodiversity and Pattani's unique culture. However, accessing these sites requires local knowledge and expert guidance due to limited transportation and accessibility. A two-day visit is recommended to thoroughly explore these places.
