Located in Songpai County, Sichuan Province, the Huanglong Area covers an area of about 700 sq. km. In a 7.5-kilometer-long valley, the travertine falls and limestone shoals, in the shape of U set between high hills and snowy mountains, run from an elevation of 3,578 meters down to 2,200 meters like a soaring yellow dragon (Huanglong in Chinese). In 1992, it was included in the UNESCO World Natural Heritage List.

The Huanglong Area is a rare site of limestone landscapes. It is also renowned for its mountain landscape, diverse forest ecosystems, waterfalls and hot springs.
