Longmenjian Canyon, about 90 kilometers from downtown Beijing, occupies an area of about 20 square kilometers and is 15 kilometers long. The canyon zigzags among the forested mountains and is known for its weird-shaped stones and steep cliffs, strangely-formed peaks and caves, lush grass and crystal water.
In the canyon, the air is fresh and cool, and people will feel much refreshed there. Because the Longmenjian Canyon has steep cliffs and narrow gorges, the relative height difference ranging from 300 to 600 meters from the peaks to the canyon bottom and the narrowest section of the canyon at less than four meters. It is humid all year round and dampness is not easy to disperse, leading to lush vegetation. The content of negative oxygen ion is high, about 400-500 times higher than that in urban areas, and it is therefore a natural oxygen bar. Due to its special landform, temperature here is 7-8 degrees centigrade lower than that in urban areas. Even in the baking summer season, it is cool here. The road extends with relatively flat slopes and it is therefore not exhausting to climb up the mountains.
Longmenjian belongs to the karst landform. The erosion of rocks is slow, the frost wedging in the rock layers is stronger than the erosion effect, it is therefore called the “cream of karst in north China.” Because it is located at the edge of the Yanhecheng great fault zone, after the orogenic movement about 150 million years ago, water flow cut into and eroded the soft rocks, and the Longmenjian Canyon was gradually developed, with numerous gorges and ravines and more than 170 different waterfalls. Water in the canyon is quality mineral water, containing several trace elements needed by the human body. The green mountains, crystal water and canyon together produce a southern China landscape, and every bend of the canyon is like a water color painting. The canyon is nicknamed “small Guilin in western Beijing” and “lesser three gorges in Beijing”. |
