Lạng SơnNorth-East Vietnam21.85° N · 106.76° E
A border province of karst hills, caves and busy markets on the road from Hanoi to Cao Bang. Here is what is worth a stop and what you can skip.
Lang Son is a province on Vietnam's north-eastern border with China, long a crossroads for trade and armies moving between the two countries. The Huu Nghi or Friendship Gate border crossing lies just north of the provincial city, and the busy markets show it: goods flow across the border every day, along with Tay and Nung communities whose villages dot the valleys.
For travellers, Lang Son is mostly a stop on the way to Cao Bang and Ban Gioc. Its limestone caves and markets fill a few hours, and the Bac Son valley, with rice fields and stilt houses below a steep peak, is the most beautiful corner of the province. In winter, the cool heights of Mau Son mountain draw Vietnamese visitors hoping for frost.
Our private, tailor-made journeys can include a stop in Lang Son or a night in Bac Son on the way to Cao Bang.

The experiences our travellers enjoy most, in order of what we would not miss.
A wide valley of rice fields and Tay stilt houses ringed by limestone peaks. Climb the viewpoint above it for the classic view, best in September and October.
Two limestone caves close to the city, with a small pagoda inside Tam Thanh. A short, easy stop.
The city's main market, busy with border trade, local produce and Tay and Nung shoppers. Interesting for an hour.
A high mountain near the border with cool weather all year and occasional frost in winter, popular with Vietnamese visitors.

Quick answers from our local team. Anything else, just ask your travel specialist.
Ask us on WhatsAppAs a stop on the way to Cao Bang, yes, especially for the Bac Son valley. The city itself has a few caves and markets but is not worth a long stay.
By road, about 3 hours. Slow trains also run towards the border. Most travellers drive through by private car on the way to Cao Bang.
Late September and October, when the rice turns golden before harvest. Spring brings fresh green fields, and early mornings often have mist lying in the valley.
