Driving Guide: Haikou to Phu Ly via Scenic QL-1A

Starting in Haikou, the capital of Hainan Island, you'll board a ferry at Xiuying Port to cross the Qiongzhou Strait—a 30-minute ride that connects to the mainland at Haikou Port. The driving route follows QL-1A (National Highway 1A), the main artery through Guangxi's limestone peaks. Covering 380 km, the drive typically takes 6.5 hours, excluding ferry wait times, which can add 1-2 hours during peak seasons.

The route passes through the Guangxi Zhuang Autonomous Region, known for its dramatic karst scenery, and ends in Phu Ly, the capital of Ha Nam Province in Vietnam. This road trip offers a mix of coastal plains, river valleys, and mountain passes, but it's not just about the destination—the journey itself is a highlight.

Safety stats indicate that the section between Pingxiang and Dong Dang has a higher rate of truck accidents due to narrow two-lane roads. Use extreme caution when overtaking. Road shoulders are sometimes unpaved, so pull off only at designated lay-bys. For families, the route is moderately child-friendly: rest areas in China have play areas (e.g., at the Nayuan service area around the 200-km mark), and most hotels in Phu Ly offer family rooms. However, long drives of 6.5 hours with a 2-hour ferry break can be tiring for younger kids, so plan stops.

Fatigue management: Plan to take a break every two hours or 150 km. Recommended stops include the Shitouduan rest stop (around the 280-km mark) which has a clear view of the karst hills, and a local coffee shop in Lang Son called Ca Phe Nha (address: 13 Nguyen Du Street) that offers strong Vietnamese iced coffee for 15,000 VND. Pet-friendly framework is limited: while Chinese rest areas allow pets on a leash, many Vietnamese restaurants do not welcome animals. Be prepared to eat takeaway or ask for a table outside. Also, note that the ferry ride may require your pet to remain in the car, so bring water and a shaded crate for the 30-minute crossing.

Border crossing: You must exit China at Youyi Guan (Friendship Pass) near Pingxiang, then cross into Vietnam at Huu Nghi Quan. The crossing is open 7 am to 10 pm daily. Have your vehicle's Carnet de Passage and international driving permit ready. Fuel costs: gasoline averages ¥7.50 per liter in China and VND 23,000 (about $1) per liter in Vietnam. The total round trip of 760 km requires about 60 liters of fuel, costing roughly $60. Tolls: QL-1A is a national highway with no tolls, but you'll pay for the ferry (¥150 per car) and a road toll on the Vietnam side (110,000 VND).

Road quality varies: Chinese sections are well-maintained with rest areas every 50 km, while Vietnamese roads are narrower and less predictable. Services along the way include gas stations, but they become sparse after Lang Son in Vietnam, so fill up before crossing. Navigation is straightforward: stay on QL-1A through Nanning, Chongzuo, Pingxiang, then cross and follow QL-1 (same route) to Phu Ly. Expect roadworks in Guangxi due to ongoing upgrades.

• Ferry from Haikou to Hai'an: 30 min, ¥150 per car.
• Border crossing at Youyi Guan is about 2 hours from Phu Ly.
• Drive time: 6.5 hours plus 1-2 hours for ferry and border formalities.

The first 100 km from Haikou to Hai'an Port passes through tropical coconut groves and rubber plantations. After crossing onto the mainland, the road skirts the Shiwan Dashan mountain range, where limestone outcrops rise abruptly from rice paddies—a landscape similar to Guilin's. A notable off-route spot is Detian Waterfall, a 30-km detour from Chongzuo. This is the fourth largest transnational waterfall in the world, measuring 200 meters across, and straddles the China-Vietnam border. Visiting costs ¥80, and the best season is May to September when water flow peaks after the rainy season.

Local commerce thrives in every town along QL-1A. In Ningming County, a popular stop for lunch, roadside eateries serve duck noodle soup, a Guangxi specialty, for about ¥10. Further south, in Lang Son, Vietnam, you'll find peach-shaped rice cakes called banh gai, sold at markets for 20,000 VND. The route passes through two UNESCO World Heritage Sites: the Trang An Landscape Complex (near Phu Ly) and the East to West Corridor (a short detour to Ninh Binh). Both offer boat rides through cave systems and are best visited in October and November when the weather is dry and cool.
