Mong Cai to Nam Dinh: Ultimate Road Trip Guide

Mong Cai, Vietnam's northeasternmost city, sits on the border with China, while Nam Dinh lies south in the Red River Delta. The drive along National Route 18 and then QL10 covers roughly 300 km, taking about 6 to 7 hours. This route takes you through the coastal strip of Quang Ninh and Hai Phong, offering a mix of industrial zones, rice paddies, and dramatic seascapes. Planning your journey requires attention to weather, road conditions, and where to stop for the best experiences.

The primary route uses QL18 from Mong Cai to Cam Pha, then QL10 through Hai Phong and on to Nam Dinh. Alternatively, the expressway from Ha Long to Hai Phong saves time, then QL10 continues. Fuel stations are frequent along QL18 but sparse between Hai Phong and Nam Dinh, so plan accordingly. Costs: tolls on the expressway total about 150,000 VND for a car; fuel consumption averages 8 liters/100 km. Expect to spend roughly 500,000 VND on fuel for the entire trip.

• Road quality: QL18 is in good condition, but watch for trucks; QL10 is adequate, but some sections are narrow.
• Highway signage is in Vietnamese; using a GPS app is advisable.
• Driving at night is not recommended due to poor lighting in rural stretches.

Exercise caution on QL18, where large trucks dominate; overtake only when visibility is clear. The route is generally safe, but wet season (May to October) brings slippery roads and occasional flooding in low-lying areas. For families, the Hai Phong Museum and the Cat Ba National Park ferry are worthwhile detours. Many restaurants along the highway offer high chairs, but not all have kid-friendly menus. Pet-friendly stops are limited: consider eating outdoors where pets can be leashed. About every 80 km you'll find rest areas with basic amenities; keep stretch breaks to every 2 hours to avoid fatigue.

Hidden off-route spots include the Vinh Nghiem Pagoda in Bac Giang province, a 13th-century Buddhist site, and the Xuan Thuy National Park near Nam Dinh, a Ramsar wetland teeming with migratory birds. For local culture, a weaving village near Kim Son offers silk products. When planning your journey, use this guide to find the how to find the best stops and hidden gems between cities and make the most of your trip.

As you leave Mong Cai, the Ha Coi River estuary gives way to the Cam Pha coast, where karst limestone formations rise from the sea. Further south, the Red River Delta flatlands are covered in emerald rice paddies and fish farms. A notable stop is Do Son Beach near Hai Phong, with its long stretch of sand and resort ambiance. For a taste of local commerce, Tien Yen market is a lively spot for northeastern specialties like smoked pork and forest honey.

UNESCO-listed Ha Long Bay is a detour from Cam Pha, but its stunning seascape is unmatched. Instead, visitors can enjoy a cruise from Tuan Chau Island. The bay's thousands of islands and caves are best explored by boat, but even a drive along the coast offers evocative views. It's worth the extra time if you haven't seen it before.
