Silk Road History Route Map: Following the Ancient Traders Through Xinjiang

Standing on the eroded rampart at Jiaohe outside Turpan in April 2021, I could see the whole plan of the city at once. Streets cut down into the loess rather than built up out of it, a monastery quarter at the north end, a wall of cliffs on both sides where two rivers split. Nobody has lived there since roughly the 1380s. The temperature was 26°C and the wind smelled of dust and nothing else.

What people call the Silk Road was never one road. Across Xinjiang it was at minimum three, forced apart by a single obstacle: the Taklamakan Desert, 337,000 square kilometres of shifting sand that caravans went around, never through. Everything about the historical geography of this region follows from that fact.

This is a practical map of those routes, the ruins that survive on each, and how to travel them now.

The Basic Geography

Coming from Dunhuang in Gansu, traffic entered Xinjiang through the Hami gap. From there it split.

The Northern Steppe Route ran north of the Tianshan through Barkol, Jimsar and what is now Urumqi, then west through the Ili Valley towards Almaty and the Central Asian steppe. Grass, water, horses, and Turkic and later Mongol power. Less Buddhist infrastructure, more mobility.

The Northern Tarim Route hugged the southern foot of the Tianshan: Hami, Turpan, Yanqi, Kuqa, Aksu, Kashgar. Oases fed by mountain meltwater every 150 to 250 km. This was the busiest corridor from the Han through the Tang, and it holds the greatest concentration of surviving Buddhist sites in Xinjiang.

The Southern Tarim Route ran along the northern foot of the Kunlun: Ruoqiang, Qiemo, Minfeng, Yutian, Hotan, Yarkant, Kashgar. Drier, harder, and the older of the two Tarim routes. Its oases shrank as rivers retreated, which is why the ruins here are buried in sand rather than standing on cliffs.

All three converged at Kashgar. From there the passes: Torugart and Irkeshtam into the Fergana Valley, and the Pamir route through Tashkurgan towards Wakhan and Gandhara.

Distances You Can Actually Plan Around

Leg	Distance	Modern travel time
Dunhuang to Hami	390 km	2 h 30 by high-speed rail
Hami to Turpan	400 km	1 h 40 by high-speed rail
Turpan to Korla	310 km	3 h by road
Korla to Kuqa	280 km	2 h 30 by train
Kuqa to Aksu	260 km	3 h by road
Aksu to Kashgar	460 km	5 h by road, 6 h by train
Kashgar to Hotan	510 km	6 h by road, 7 h by train
Hotan to Ruoqiang (southern route)	1,090 km	2 days by road
Korla to Minfeng (desert highway)	560 km	7 h by road

The desert highway from Luntai to Minfeng, opened in 1995 and 552 km long, is the one thing caravans never had. It cuts straight across the Taklamakan and turns a three-week detour into a seven-hour drive. The Taklamakan desert highway guide covers the drive itself.

The Eastern Gateway: Hami and Turpan

Hami was the funnel. Everything from the Hexi Corridor passed through, which is why the Tang built garrisons here and why control of Hami changed hands so often. The Hami Kings’ Tombs and the Uyghur royal complex are the visible legacy, along with a melon industry that is somehow just as famous. Our Hami guide handles the town.

Turpan is the richest single archaeological zone in Xinjiang, and the reason is climate. Rainfall of around 16 mm a year preserves wood, paper, textile and human remains that would have rotted anywhere else.

Jiaohe. Capital of the Cheshi kingdom, later a Tang garrison, on a 1,650 m long island of loess between two river channels. Abandoned after Mongol-era warfare in the 13th to 14th century. Entry around ¥70. Go at 08:00 or after 18:00 in summer, because there is no shade anywhere on the site and I have measured 44°C on that plateau in July.

Gaochang. Larger, 30 km southeast of Turpan, a walled city of about 2 square kilometres founded in the 1st century BCE and abandoned in the 14th. Xuanzang lectured here in 630 CE at the invitation of its king. Entry around ¥70, plus a donkey cart across the site for ¥30 that is worth taking.

Bezeklik. 77 rock-cut caves in a gorge in the Flaming Mountains, painted between the 5th and 14th centuries. A large share of the murals were cut out and removed by Albert von Le Coq’s German expeditions between 1904 and 1913, and much of what went to Berlin was destroyed by Allied bombing in 1945. What remains on site is fragmentary. Standing in a cave with rectangular scars where paintings used to be is a specific kind of unpleasant.

Astana tombs. Cemetery of Gaochang, in use roughly 3rd to 8th century, source of thousands of documents, textiles and preserved bodies now largely in the Xinjiang Regional Museum in Urumqi.

The Northern Tarim Route: Kucha and the Buddhist Heartland

Kucha was the largest of the Tarim city-states and the most culturally productive. Its language, Tocharian B, is an Indo-European language spoken 5,000 km east of anywhere else Indo-European languages were used, which took philologists most of the 20th century to digest.

Kizil Thousand Buddha Caves. 236 numbered caves, 67 km west of Kuqa, with painting from roughly the 3rd to the 8th century. This is the oldest major Buddhist cave complex in China, predating Dunhuang’s Mogao caves. The Indo-Iranian style here, with the diamond-pattern mountain compositions, is unlike anything further east. Entry around ¥70, with a handful of caves open on rotation and a guide required.

Kumtura and Simsim caves. Smaller, harder to access, generally requiring arrangement in advance.

Subash. A monastery complex on both banks of the Kucha River north of town, active from the 3rd to the 9th century and once housing, by some accounts, over a thousand monks. Xuanzang stayed here for two months in 630. Now it is standing mud-brick shells against a backdrop of red mountains, with almost nobody there. Entry around ¥30. Our Subash guide has the access details.

Kumarajiva was born in Kucha in 344 CE, taken to Chang’an as a war prize, and translated the Lotus Sutra and much of the core Mahayana canon into Chinese. Arguably the single most consequential person ever produced by this region.

The Southern Route: Buried Kingdoms

The southern route is the hard one, both historically and now. Its cities did not decline politically so much as run out of water.

Loulan. On the edge of the dried Lop Nur basin, abandoned around 330 CE when the Tarim River shifted. Sven Hedin found it in 1900. It is inside a restricted military and nature reserve, requires special permits typically costing ¥5,000 to ¥20,000 per person through licensed operators, and involves several days of desert driving. Most people will not go, and should not plan on it.

Niya. 115 km north of Minfeng, deep in the sand, the Jingjue kingdom, abandoned around the 5th century. Kharosthi-script wooden documents from here are among the best evidence we have for daily life on the southern route. Access requires desert vehicles and permits, arranged in Minfeng, realistically ¥4,000 to ¥8,000 for a group.

Rawak stupa. 40 km north of Hotan, a cruciform stupa with a surrounding wall that once held colossal stucco figures. Reachable with a local driver and a permit, sometimes closed.

Melikawat. 25 km south of Hotan on the Yurungkash river bank, an accessible ruin field where you can pick up potsherds off the ground, which you should look at and put back.

Hotan itself was the jade source. Nephrite from the Yurungkash and Karakash rivers reached the Shang capital at Anyang by around 1200 BCE, which means jade was moving east along this corridor roughly a thousand years before silk moved west. The Hotan guide covers the modern jade market, which still operates on the riverbed every morning.

The Northern Steppe Route

Less visited and archaeologically thinner, but it carried a different kind of traffic: horses, furs, and armies.

Beiting (Beshbalik), near Jimsar, was the Tang Protectorate General of the Pacified North, established 702 CE. The site covers about 1.5 square kilometres with an inner and outer city and a Buddhist temple complex with surviving murals in a covered hall. Entry around ¥40. I have been twice and seen four other visitors in total.

Barkol and the Tianshan north grasslands carried the route towards the Ili Valley and the Zhetysu region. The modern Duku Highway crosses between the northern and southern systems over the Tianshan, which historical caravans did through a handful of difficult passes and mostly avoided.

What Actually Moved

Silk went west. Everything else is more interesting.

Jade went east from Hotan, from the second millennium BCE. Horses came east from Fergana, and the Han dynasty fought a war in 104 to 101 BCE to get them. Paper moved west and reached Samarkand after 751. Buddhism moved east through Gandhara into Kucha and Khotan and from there to China, which is why the earliest Chinese Buddhist translators were Central Asians. Manichaeism and Nestorian Christianity both took root in the Turfan oasis, and Manichaean manuscripts in three scripts were found at Gaochang.

Also moving: grapes, alfalfa, walnuts, pomegranates, glassmaking, musical instruments, and a great deal of disease.

Trade was almost entirely relay. A merchant from Sogdiana did not travel to Chang’an and back. Goods changed hands six or eight times, and Sogdian traders from Samarkand ran the middle sections so thoroughly that Sogdian became the commercial lingua franca of the entire corridor.

A 14-Day Route That Works Today

This is roughly the trip I would design for someone with two weeks who cares about the history rather than the scenery.

• Days 1 to 2, Urumqi. Xinjiang Regional Museum, half a day minimum. The Tarim mummies and the Astana textiles frame everything that follows.
• Days 3 to 4, Turpan. Jiaohe, Gaochang, Bezeklik, Astana, Turpan Museum, karez irrigation. High-speed rail from Urumqi takes 1 hour.
• Day 5, Korla. Transit, with the Iron Gate Pass if you have interest.
• Days 6 to 7, Kuqa. Kizil caves, Subash, Kuqa Grand Mosque, the old town.
• Day 8, Aksu. Transit.
• Days 9 to 10, Kashgar. Old town, Id Kah, Mor pagoda ruins outside the city, Sunday markets.
• Days 11 to 13, Hotan. Jade market, Melikawat, Rawak if permitted, carpet and silk workshops, Sunday bazaar.
• Day 14, return via Hotan to Urumqi flight, roughly 2 hours.

Budget: ¥9,000 to ¥15,000 per person for two weeks including internal flights, mid-range hotels, entry fees and a driver for the Kuqa and Hotan segments. Rail covers most of the trunk route now and is the cheapest way to link the oases, which our Xinjiang train travel guide lays out.

Practicalities for Ruins

• Heat. Turpan and the southern oases exceed 40°C from late June to late August. Ruins have no shade. Plan for 07:30 starts or 18:30 visits.
• Entry fees. Most sites ¥30 to ¥80. Kizil and Bezeklik have additional photography restrictions and separate charges for certain caves.
• Photography inside caves is generally banned. Enforcement is real. I watched a phone get confiscated at Kizil for the duration of the tour.
• Permits. Loulan, Niya, and some border-adjacent sites need advance arrangement, weeks not days.
• Guides. Site guides at Kizil are mandatory and Chinese-speaking. Hiring an English-speaking guide from Kuqa costs ¥400 to ¥800 a day and is the difference between looking at a wall and understanding it.
• Best months. April to early June, and September to October. Spring gets dust storms, autumn is cleaner.

The Thing Worth Understanding

The oases along these routes were not stops on a Chinese road. They were independent kingdoms with their own languages, coinage, art and religion, sometimes tributary to Chang’an, sometimes to the Turks, sometimes to Tibet, frequently to nobody. Khotan spoke an Iranian language and painted in an Indian style and minted coins with Chinese characters on one side and Kharosthi on the other. That is what this corridor produced.

At Jiaohe that April afternoon I walked the main avenue from the south gate to the great monastery, about 350 m, in eleven minutes. Fourteen hundred years ago it would have taken longer because the street would have been full. Go early, bring 2 litres of water, and give each of these sites twice the time the guidebooks suggest.
