The Cihara (often written as Ci Hara) is a river located in the Lebak Regency of Banten, Java, Indonesia.
The headwaters are situated southwest of Mount Halimun Salak National Park, around the West Citorek. Flowing for a distance of 29.6 km[2] from the northeast to the southwest towards the southern coast of Banten until it meets the Indian Ocean, approximately in the District of Cihara.[3] The upstream of Cihara at an elevation of around 860 meters above sea level, there is an archaeological site located in Dusun Cibedug, West Citorek. The Lebak Cibedug site covers an area of approximately 40 km2 (15 sq mi). In this prehistoric site, numerous Megalithic-era structures are found, including terraced mounds, menhirs, and stone tables like dolmens.[4] Meanwhile, at the river mouth location, there is an expanse of various types of pebble-sized to cobble-sized rocks, ranging from igneous rocks, sedimentary rocks, metamorphic rocks, and quartz vein rocks containing metallic minerals, even coal and fossilized wood fragments. These rock fragments are believed to have been carried to the coast by the flow of the Cihara River, then stirred by extreme waves from the southern sea (Indian Ocean) for thousands or even millions of years, resulting in rounded shapes with smooth to very smooth surfaces. Various types of rocks originate from along the Ci Hara River, from the upstream area to around the river mouth.[5]
