To the east of Yanling County, the Shennong Valley National Forest Park is a natural reserve, with 90 percent forest coverage. The park is a gene bank of rare natural animals and plants. It acquired its name Shennong (also called Emperor Yan) Valley Park because it is close to the Mausoleum of Emperor Yan. Covering an area over 100 square km, the park has hundreds of peaks, including the highest one in Hunan Province- Shennong Peak (2122.35meters above sea level). The main tourist attractions in the forest park include the Pear Curtain Waterfall, which contains the most negative oxygen ions in Asia; Shennong Flying Waterfall, the highest waterfall in Hunan; and the primeval forest with an area of 6,666 hectares, the only such forest at the confluence of East, South and Central China in the country. Taking a tour to the Shennong Valley National Forest Park, tourists will find everything fresh and new, and feel rejuvenated.
