Limestone Landscapes
The main attraction of the Huanglong valley is the 3.6-kilometer-long and 30 to 70-meter-wide pale yellow calcareous deposits. At the end of the valley, water from melting snow mixes with limestone water from underground, flowing down the mountain terraces, depositing the calcium carbonate from the limestone water on the rocks, stones, and fallen branches in its path. The calcium carbonate, in turn, develops into solid, low travertine banks and reacts chemically with organic and inorganic substances, resulting in various kinds of calcareous deposits that reflect a golden color in the sunlight in the water that flows down the slopes just like a huge yellow dragon flying down the snow mountain. When water flows into two separate streams, it naturally turns into more colorful lakes and waterfalls, forming a ladder-shaped lake group. The water is crystal clear. The mineral deposits at the lake bottom look like jadeite and agate – magnificent and beautiful.
Huanglong Temple (Yellow Dragon Temple) 
The temple lies at the foot of Xuebaoding, the major peak of Mt. Minshan. At a distance of about 20 miles off the entrance of the valley, it provides a retiring place for the visitors. The temple consists of three small ones - the front, the middle and the rear temples, which mark the head, the waist and the tail of a dragon respectively, going all the way down the valley. The front temple has almost been ruined. The middle temple has five halls remaining, to worship the Goddess of Mercy, and the 18 arhats. As for the rear temple, it enshrines the Dragon King.
On the 15th of every sixth lunar month, the day when the yellow dragon was said to achieve his Buddha hood, a big temple fair is held in the rear temple. At that time, local people of different groups come to attend, praying for good fortune and harvests. Young people also find it the best time to tell sweet words to their lovers.
Huang Long Cave(Yellow Dragon Cave) 
This huge cave, lies behind the rear temple, is filled with stalactites. In winter, there are icicles and ice waterfalls hanging inside. Left of the hall in the cave, there are three seated Buddha statues from the Ming dynasty (A.D.1368-1644). Now all of them are coated with a thick layer of lime deposits.
