The third longest river, the Pearl River, measures 2,129 meters in length. The Guangzhou section of the river is where Guangzhou's most scenic spots are located. Many famous sights are clustered along the river and are the reasons for many people taking a trip to Guangzhou.
The Pearl River got its name from a huge rock island. When the thousand-meterlong Pearl River cut through Guangzhou City, a large rock island in the centreof the river was scoured over. Over time this became smooth and bright like a pearl, hence the rock being named "Sea Pearl Rock" and the river "Pearl River".
