About This Attraction

The Summit of the National Highway 318

Located deep within the Hengduan Mountains in Zuogong County, Chamdo, lies a formidable geographical marker known as Dongda Mountain Pass (Dongda La). Standing at a staggering altitude of 5,130 meters, it is often considered the highest mountain pass on the entire Sichuan-Tibet South Line (G318), surpassing the famous Mila Mountain Pass in elevation,. It serves not only as a physical barrier but as a "golden stone" testing the will and endurance of travelers. Geographically, it acts as the watershed between the Lancang River and the Nu River basins. The pass is renowned for its harsh environment; a local saying describes it as a place where "eagles cannot fly over, and grass does not grow," highlighting its barren, rugged beauty and the extreme challenge it posed to travelers throughout history,.

A Landscape of "Four Seasons in One Day"

1.Dongda Mountain: Pass is famous for its volatile and unpredictable weather, offering visitors the unique experience of witnessing "four seasons in a day." One moment, the pass may be bathed in intense, high-altitude sunshine that illuminates the red soil mountains and distant snow peaks; the next, it can be engulfed in wind, snow, or hail. The landscape here presents a dramatic contrast: looking east, one sees the winding, ribbon-like roads climbing up from the valley; looking west, the view opens up to the profound and vast Tibetan plateau. The mountains are often devoid of vegetation, exposing distinctive red and brown soil that contrasts sharply with the white snow, creating a desolate yet magnificent visual impact that captivates photographers,.

2.From the Ancient Tea: Horse Road to the "Two Roads" Spirit

Historically, this pass was a "life and death barrier" on the ancient Tea Horse Road. Caravans carrying tea and salt faced immense hardships crossing this "Sky Road" where oxygen is thin and temperatures are freezing. Today, the G318 highway traces the path of these ancient travelers. The pass stands as a testament to the "Two Roads Spirit" (referring to the construction of the Sichuan-Tibet and Qinghai-Tibet highways), memorializing the sacrifice and determination of the road builders who carved a path through this "forbidden zone" of life in the 1950s. For modern self-driving travelers and cyclists, reaching the 5130-meter marker is a rite of passage, symbolizing a victory over oneself and nature,.

A Sacred Space of Fluttering Prayer Flags

Despite the harsh conditions, the pass is a spiritual sanctuary. Colorful prayer flags (Lungta) flutter violently in the strong mountain winds, carrying prayers and blessings to the heavens with every flap. Heaps of Mani stones carved with scriptures sit silently by the road, placed by devout pilgrims and travelers seeking safety. High-altitude wildlife, such as marmots and eagles, can occasionally be seen, adding a touch of vitality to this barren land. Standing at the pass, surrounded by snow-capped peaks and prayer flags, travelers often feel a profound sense of awe and a connection to the spiritual atmosphere of the Tibetan Plateau,.
