The Silk Road: Xi'an to Kashgar along the ancient trade route

The Silk Road is not one road but a network of trade routes that connected China to Central Asia, Persia, and Europe for 1,500 years. The Chinese section — from Xi'an to Kashgar — is the most accessible and best-preserved stretch. You travel through three distinct cultural zones: Han China in Shaanxi, the Buddhist cave-temple belt in Gansu, and Turkic-Uyghur Central Asia in Xinjiang. Each province feels like a different country.

The highlights are genuinely world-class. The Terracotta Army outside Xi'an (8,000 life-size clay soldiers, discovered 1974) opens the journey. The Mogao Caves at Dunhuang — 492 painted cave temples with 45,000 square metres of Buddhist murals spanning 1,000 years — are, in my view, the single most important cultural site in China outside Beijing. The Singing Sand Dunes and Crescent Lake at Dunhuang are a desert landscape that looks photoshopped but is absolutely real. Turpan's Grape Valley and the ruins of Jiaohe (a city carved into a plateau, abandoned after Genghis Khan) show how civilizations adapted to one of the driest places on earth. And Kashgar's Sunday Bazaar — 100,000 people, livestock, spices, carpets, and the sense that you have genuinely arrived somewhere distant — is one of the great market experiences left in the world.

I have done the Xi'an-to-Kashgar route twice, once by train and once by a mix of train and flight, and the sequence works best westbound — you ease into Central Asia gradually rather than getting thrown into Kashgar on day one. The cultural transition from Xi'an (thoroughly Han, noodles and dumplings, imperial history) to Lanzhou (still Han but rougher, the Yellow River, beef noodles for breakfast) to Dunhuang (Buddhist, desert, Silk Road caravan history) to Turpan (Uyghur, vineyards, mosques, Central Asian food) to Kashgar (overwhelmingly Uyghur, the Id Kah Mosque, the Sunday Bazaar) is one of the great travel experiences on earth.

Two to three weeks is the sweet spot. In 14 days you can cover Xi'an → Lanzhou → Zhangye → Jiayuguan → Dunhuang → fly to Urumqi → fly to Kashgar, with one full day at each major stop. In 21 days you add Turpan between Dunhuang and Urumqi, plus a day trip from Kashgar toward the Karakoram Highway to Karakul Lake (3,600m, with views of Muztagh Ata, the 7,546m "Father of Ice Mountains").

A realistic 14-day itinerary: Days 1-3: Xi'an (Terracotta Army, city wall bike, Muslim Quarter). Day 4: HSR to Lanzhou (3h), afternoon along the Yellow River, beef noodles at a 24-hour shop. Day 5: Day trip to Bingling Temple caves (¥50 boat, 2h each way). Day 6: HSR to Zhangye (3h from Lanzhou), afternoon at Danxia landforms. Day 7: Zhangye Giant Buddha Temple (34.5m-long reclining Buddha, 11th century), afternoon HSR to Jiayuguan (1h). Day 8: Jiayuguan Fortress and Overhanging Great Wall. Day 9: HSR to Dunhuang (4-5h from Jiayuguan), evening at Singing Sand Dunes for sunset. Day 10: Mogao Caves (book 2+ weeks ahead for peak season, ¥238 as of June 2026), afternoon at Crescent Lake. Day 11: Fly Dunhuang → Urumqi (1.5h, ¥600-900) or take the 12h sleeper train. Day 12: Urumqi — Xinjiang Regional Museum (see the 3,800-year-old Tarim mummies), Grand Bazaar, Heavenly Lake if time permits. Day 13: Fly Urumqi → Kashgar (2h, ¥800-1,200). Day 14: Kashgar Sunday Bazaar (plan your dates around a Sunday — the bazaar is a shadow of itself on weekdays), Id Kah Mosque, old city alleys.

The key logistical constraint is the Dunhuang–Turpan–Urumqi stretch. The HSR line covers Lanzhou–Urumqi in one 11-hour shot but bypasses Dunhuang. Dunhuang has its own HSR spur from Lanzhou, but onward to Turpan requires a flight or a long bus. Most travelers fly Dunhuang → Urumqi to save a day. The Urumqi–Kashgar flight (2h) is the single essential flight — the alternative is a 24-hour train or a 20-hour bus through the Taklamakan, which I do not recommend unless you specifically want that experience.

High-speed rail is the backbone. The Lanxin HSR line connects Lanzhou to Urumqi in about 11 hours, with stops at Xining, Zhangye, Jiayuguan, and Turpan along the way. The Xi'an–Lanzhou HSR (3 hours) links the start to the corridor. HSR is comfortable, punctual, and cheap — second-class seats on the Lanzhou–Urumqi run cost about ¥550 (US$76). The downside: HSR stations are often far from the actual sights (Jiayuguan station is 20 km from the fortress; Dunhuang station is 15 km from the Mogao Caves), so budget ¥30-60 for taxis at each stop.

For the desert stretches where HSR doesn't reach — specifically Dunhuang to Turpan — you have three options: fly (1.5h, ¥600-900, runs 2-3 times weekly), take the overnight sleeper train (12h, ¥200-300 for a hard sleeper), or hire a car with a driver (10-12h, ¥1,500-2,000, split among 3-4 people). I've done the sleeper train once — it is an experience and not a pleasant one. The flight is worth the money.

Within cities, DiDi works in Xi'an, Lanzhou, Urumqi, and Kashgar (though Kashgar DiDi coverage is thinner — taxis are plentiful and ¥6 flagfall). In smaller stops like Zhangye and Jiayuguan, taxis are the main option and are cheap (¥10-20 across town). For the Mogao Caves: a dedicated tourist bus runs from Dunhuang city centre (¥8, 30 min). For the Bingling Temple Caves from Lanzhou: a combination of bus to Liujiaxia Dam (2h, ¥30), then a boat through the reservoir (¥50-120 depending on speed). For Karakul Lake from Kashgar: hire a car and driver for the day (¥600-800 for a 4-5 hour trip up the Karakoram Highway to 3,600m — the road is good, the border with Pakistan is 200 km further).

Safety: The Silk Road is safe for foreign travellers. The main risks are traffic accidents (Chinese driving standards on desert highways are relaxed), altitude sickness at Karakul Lake (3,600m — spend a day acclimatizing in Kashgar at 1,300m first), and dehydration in the desert stretches. The Xinjiang security presence is heavy — expect passport checks at hotel check-in, metal detectors at transport hubs, and a visible police presence at bazaars and mosques. This is normal and not directed at foreign tourists. Carry your passport at all times.

Food: This is one of the great food routes in the world. In Xi'an: yangrou paomo (crumbled flatbread in lamb soup) and grilled skewers in the Muslim Quarter. In Lanzhou: Lanzhou beef noodles (兰州牛肉面, Lánzhōu niúròu miàn) — the canonical breakfast, hand-pulled to order, ¥15-25 a bowl. In the Hexi Corridor (Zhangye, Jiayuguan):搓鱼面 (cuōyú miàn, "fish-rubbed noodles") and lamb with cumin. In Dunhuang: donkey-meat noodles (驴肉黄面, lǘròu huáng miàn). In Turpan and Urumqi: the food shifts to Central Asian — polo (pilaf rice with lamb and carrot), laghman (hand-pulled noodles with lamb and vegetables), naan bread baked in tandoor ovens, and the best grapes and melons in China (Turpan grapes in August-September are extraordinary). In Kashgar: the Sunday Bazaar food section has whole roasted lamb, samsa (baked meat pies), fresh pomegranate juice (October-December), and Uyghur ice cream.

Practical: Internet is restricted across China and VPNs are essential. In Xinjiang, VPNs are actively blocked and the internet is slower and more restricted than in eastern China — download maps, translations, and reservations before you enter Xinjiang. English is rare west of Xi'an — a translation app (Pleco or Microsoft Translator with offline Chinese pack) is essential. Cash is still useful in Xinjiang markets (¥30-50 for a meal, ¥5-10 for naan). Alipay and WeChat Pay work everywhere except small market stalls in Kashgar and Turpan.

Altitude: Most of the route is under 1,500m. The exception is Karakul Lake (3,600m) near Kashgar, on the Karakoram Highway. If you are flying directly from sea-level cities to Kashgar and then driving up the same day, you may feel the altitude — headache, shortness of breath. Spend your first Kashgar day at 1,300m before heading up.

April–June and September–October are the prime windows. In April, the desert is cool (15-25°C), the apricot blossoms are out in the Kashgar region, and tourist numbers are low. May is warmer and drier, with the Mogao Caves and Terracotta Army at comfortable crowd levels before the summer surge. June can be hot in Turpan (35-40°C) but the rest of the route is pleasant. September–October is the consensus best window: clear skies, crisp air, autumn grape harvest in Turpan (September), and the golden poplar trees along the Hexi Corridor turning in October. The light for photography is at its best.

July–August is the peak domestic tourism season. Xi'an, the Mogao Caves, and Kashgar are crowded; hotel prices rise 30-50%; train tickets sell out days ahead. The Turpan Depression hits 45°C+ in July. I travelled the route once in August and regretted it — the Mogao Cave queues were 90 minutes, the Dunhuang dunes were packed, and the heat in Turpan was genuinely oppressive. If summer is your only option, book everything (trains, Mogao tickets, Dunhuang hotels) at least 2-3 weeks ahead.

November–March is the low season. Xi'an and Lanzhou are cold but manageable. Dunhuang in winter is quiet and the Mogao Caves have fewer visitors, but some guesthouses close and the Singing Sand Dunes can be bitter cold (-10°C with wind). The Tian Shan near Urumqi is a ski destination in winter. The Karakoram Highway to Karakul Lake may close after heavy snow (check road conditions in Kashgar). The main constraint: some Turpan sites reduce hours or close in the deepest winter (January–February).

Solo travel on the Chinese Silk Road is completely doable — I did my first trip solo — but it requires more planning than eastern China. The HSR is efficient, DiDi works in the main cities, and hotels are accustomed to foreign guests. The main challenge is loneliness in the long transit stretches (the Lanzhou–Urumqi HSR is 11 hours of desert) and the language barrier west of Xi'an. The compensating upside: Silk Road travellers tend to find each other. The Dunhuang hostels (Silk Road Dunhuang Youth Hostel, ¥60-80 dorm bed) and Kashgar (Pamir Youth Hostel, ¥50-70) are classic backpacker hubs where you will meet other independent travellers swapping tips on the Karakoram Highway, the Mogao ticket situation, and which Turpan guesthouse has the best grapes.

For families, the route works well with some adjustments. Children under 10 will find the long HSR rides tiring — break the journey more often or fly the longest stretches (Dunhuang–Urumqi, Urumqi–Kashgar). The sights that work best for kids: the Terracotta Army (every child is fascinated), the Singing Sand Dunes (sliding down the dunes on a rented sandboard, ¥30, is the highlight), the Kashgar Sunday Bazaar (animals, colours, noise), and the Karakul Lake day trip (yaks, mountains, wide-open space). The Mogao Caves are harder for young children — the tours are 75 minutes in dim caves with no touching and no photos. Teenagers engaged by history will find them extraordinary; children under 8 may not last the tour.

A family-friendly 14-day itinerary: Xi'an (3 days) → fly to Dunhuang (2 days, skip the long train) → fly to Urumqi (2 days) → fly to Kashgar (2 days) → fly back. This cuts the long HSR stretches and focuses on the five strongest stops.
