Before the expressway corridor existed, combining Ha Long and Mong Cai into a short trip was quite exhausting. Today, the Hai Phong – Ha Long – Van Don – Mong Cai expressway network forms a continuous corridor running through most of Quang Ninh. According to the planning dossier updated in 2026, the Ha Long – Van Don – Mong Cai section spans approximately 151 km, cutting travel time between Ha Long and Mong Cai from nearly 4 hours down to just over 2 hours.

This makes Mong Cai much more accessible, but it does not mean you should rush through it like this: Ha Long → Mong Cai → Tra Co → Sa Vi → lunch → return to Ha Long in just a few hours.

Why stay overnight?

Mong Cai is not merely a border gate photo op. Since you have traveled this far, you also have:

  • The border town atmosphere.

  • Tra Co.

  • Binh Ngoc.

  • Tra Co Communal House.

  • Local cuisine.

  • The morning rhythm of coastal life.

If you return immediately, most of your day will be spent on the expressway.

A reasonable 2-day itinerary

Day 1:
Ha Long → Mong Cai → explore the town center → Tra Co → overnight in Mong Cai/Tra Co.

Day 2:
Sunrise at Tra Co → visit suitable cultural sites → lunch → return to Ha Long.

If your next stop is Binh Lieu, you can build a dedicated Eastern Quang Ninh itinerary instead of heading straight back to Ha Long.

Traveling by private car

This is the most convenient option for group travel. However, note that long stretches of highway at steady speeds can easily cause drowsiness. Take breaks when tired instead of pushing for a "record travel time." The CT.06 expressway corridor now runs directly from Hai Phong to Mong Cai, with interchanges at Ha Long, Van Don, Tien Yen, Dam Ha, Hai Ha, and Mong Cai.

Traveling by motorbike?

Motorbikes are not allowed on the expressway. Therefore, the travel time and route are entirely different from driving a car. Do not rely on Google Maps car driving times to plan your motorbike schedule. If your goal is a road trip adventure, treat the standard roads as part of the journey and stay overnight along the route if needed.

Checklist

  • Car: take full advantage of the expressway.

  • Motorbike: expressway access is prohibited.

  • Don't treat Tra Co as a "30-minute stopover."

  • A two-day trip is much more enjoyable.

  • Do not schedule a return to Ha Long with an immediate cruise boarding.

  • On long drives, rotate drivers whenever possible.
