Yarlung Valley
On Mount Sotang Kangbori, at 4,060 meters, there is a cave where the bodhisattva Avalokitesvara is said to have taken the form of a red monkey and fathered six sons with a white ogress. Those sons became the ancestors of Tibet's six original clans. The cave still shows a naturally occurring image of a monkey on its walls. Below it stretches the Yarlung Valley, 72 kilometers long, and widely regarded as the cradle of Tibetan civilization, a place so dense with origin stories that walking its length feels like reading the first chapters of an entire culture.
The Cradle Takes Shape
The Yarlung Valley is formed by the Yarlung Chu, a tributary of the Tsangpo River, in the Shannan Prefecture of the Tibet Autonomous Region. Where the Yarlung Chu meets the Chongye River, the terrain broadens into a plain about two kilometers wide before flowing into the Tsangpo. The capital of the prefecture, Tsetang, sits at the valley's heart, 183 kilometers southeast of Lhasa. Once well-forested and suitable for agriculture, the Tsetang district remains famous for its apples and pears. This was the original seat of the Yarlung dynasty, which controlled ancient trade routes into India and Bhutan. The first Tibetan Emperor, Songtsen Gampo, ruled from here before moving the capital to Lhasa after expanding his territories and power in the 7th century.
Three Power Places
The valley contains three renowned power places, the ne-sum. Sheldrak is a complex of meditation caves in the Pema Tsekri range, including the cave where Padmasambhava first meditated in Tibet, compelling indigenous demons to swear allegiance to Buddhism. Tradruk Temple, possibly predating the Jokhang in Lhasa, is one of Tibet's earliest geomantic temples, said to pin down the left shoulder of a supine ogress beneath the land. And Yumbulagang Palace, perched on a hilltop above the river, claims the title of Tibet's first building, palace of the legendary king Nyatri Tsenpo who descended from the heavens on a sky-cord. Three sacred stupas complement these sites: Takchen Bumpa, Gongtang Bumpa, and Tsechu Bumpa, each serving as a receptacle for relics and a marker on the valley's pilgrimage circuits.
Monasteries Old and Older
Samye Monastery, the first Tibetan Buddhist monastery, was established in the valley under King Trisong Deutsen. Construction began around 763 by the Indian scholar Shantarakshita, with Padmasambhava completing it in 779. It became the site of Tibet's first monk ordinations. Mindrolling Monastery, meaning Place of Perfect Emancipation, was founded in 1676 as one of the six mother monasteries of the Nyingma school. Riwo Choling, now in immense ruins south of Tradruk Temple, was founded in the 15th century by the first Panchen Lama, Khedrup Gelek Pelzang, a foremost disciple of Tsongkhapa. Its monks once served as caretakers of Yumbulagang. Chode Gong, dating to the 11th century, and Chode O, founded by the 5th Dalai Lama, stand near Tsetang as layered evidence of how each generation of Tibetan Buddhism built upon the last.
Iron Bridges and Sacred Mountains
Just below Tsetang, five large stone supports are all that remain of a 14th-century iron suspension bridge built across the Yarlung Tsangpo by the engineer Tangtong Gyalpo, a figure legendary for spanning Tibet's gorges with chains of iron. When the explorer Sarat Chandra Das visited in 1879, the bridge was already in such disrepair that he crossed by boat alongside traders and their donkeys. At the valley's far end, Mount Yarlha Shampo rises to 6,636 meters, the abode of a powerful mountain god of the same name. The road to its peak passes over the Yarto Drak La at 4,970 meters, marking the valley's terminus and the gateway to the Nyel Valley and the borders of India and Bhutan. Podrang Village, about five kilometers south of Yumbulagang, claims to be the oldest village in Tibet, one more first in a valley that seems to collect them.
From the Air
The Yarlung Valley extends along the Yarlung Chu tributary of the Tsangpo River, centered near 29.28N, 91.62E in Shannan Prefecture. Elevation ranges from approximately 3,500 meters in the valley floor to 6,636 meters at Mount Yarlha Shampo. Nearest major airport is Lhasa Gonggar (ZULS), about 150 km northwest. The valley is 72 km long, oriented roughly northwest-southeast. Key visible landmarks include Yumbulagang Palace on its hilltop, the circular layout of Samye Monastery near the Tsangpo, and the broad agricultural plain near Tsetang. Best viewed at 12,000-15,000 feet for full valley perspective.
