Driving from Liuzhou to Bac Kan: Route Guide and Stops

The highway from Liuzhou to Bac Kan traces the Chinese-Vietnamese frontier, a route that crosses the Youjiang River basin and climbs into the Truong Son Range's northern folds. A distinctive feature: the Lai Chau border gate near Dong Dang sees a daily fluctuation of trucks, and by 8 AM, queues can extend 2 km unless you start early.

Infrastructure safety: The Chinese section is modern multi-lane highway, while Vietnamese QL3 is mostly two lanes with occasional uneven pavement. Watch for motorbikes and livestock crossings, especially near villages. Keep headlights on at all times as a precaution.

Family suitability: This route is best suited for children over 3 due to long drive times. For pet-friendly framework, many hotels along the way accept pets, but confirm in advance. For example, in Bac Kan, the Khach San Bac Kan Hotel allows pets with a surcharge of 100,000 VND per night.

Fatigue management: Pack snacks and water; major rest stops are at Dong Dang, Na Ri, and Bac Kan. On Vietnamese side, rest stops are few, so plan breaks every 2 hours. Hidden off-route spots: The limestone caves of Nguom Ngao near Cao Bang (approx. 60 km off QL3) are a quieter alternative to crowded sites.

Start in Liuzhou on the Guizhou-Guangxi Expressway (G75) heading southwest, then transition to National Highway G210 toward Nanning. Near Chongzuo, merge onto QL3 (National Road 3) that leads to the Friendship Pass border crossing. After clearing Vietnamese immigration at Huu Nghi Quan, follow QL3 directly to Bac Kan, bypassing Lang Son if you stick to the main highway.

• Fuel stops: In Liuzhou, fill up at Sinopec stations near the expressway entrance; average price for 92-octane is 7.2 CNY/L (as of 2025). In Vietnam, Petrolimex stations are common along QL3, with gasoline around 23,000 VND/L.
• Tolls: A toll for the G75 segment from Liuzhou to Nanning costs ~80 CNY, payable by cash or ETC. Vietnamese highways (QL3) have no tolls except for a few bridges, like the Thanh Lang bridge (10,000 VND).
• Border crossing: Huu Nghi Quan (Friendship Pass) is open 7 AM to 10 PM (local time). Prepare your passport, Chinese exit stamp, and Vietnamese visa (or visa-on-arrival letter). Expect 1–2 hours processing during peak hours.

The drive transitions from the karst peaks of Guangxi to the terraced rice fields of northern Vietnam. Around 50 km after the border, look for the Ban Gioc Waterfall detour (approx. 30 km east on a local road) – it’s a UNESCO-listed site shared with China, and a scenic spot not to be missed.

Climatic conditions: The route experiences a subtropical monsoon climate; summer months (May-Sep) average 28°C with heavy rainfall, while winter (Dec-Feb) can drop to 10°C with fog in the mountains. The best time for driving is March-April or October-November, when skies are clear and landscapes green.

Local commerce thrives along rest stops like Dong Dang’s market and Bac Kan’s weekend fair. Try local dim sum in Dong Dang and grilled fermented pork in Bac Kan, but note that menus are predominantly in Vietnamese – a translation app helps.
