Top Things to See & Do in Bac Son
Bac Son Valley Rice Fields
The heart of the region is Bac Son Valley, a vast basin of rice fields surrounded by limestone karst mountains. The scenery is spectacular from every viewpoint across the valley.
Bac Son Valley rice fields are especially stunning during the rice harvest seasons, when the fields turn golden beneath the surrounding peaks. The main harvest periods are late July to early August and late October to November.
Outside the harvest season, Bac Son Valley is equally beautiful, with vibrant green rice fields during May to June and September to October, making it one of the most scenic times to visit Bac Son Valley in northern Vietnam.
Flower Valley (Thung Lung Hoa)
Located just over 10 km south of Bac Son, Flower Valley (Thung Lung Hoa) is a former farming area transformed into a colorful flower valley surrounded by limestone cliffs, making it one of the most photogenic places in Bac Son.
The valley changes throughout the year:
- July to October: a wide variety of flowers bloom, making this the best time to visit Flower Valley.
- November: pink buckwheat flowers cover the valley, creating a striking contrast with the grey limestone karst mountains.
Because Flower Valley lies directly on the Hanoi – Bac Son – Cat Ba route, it is an easy and rewarding stop on a northern Vietnam motorbike journey.
Na Lay Peak – Best Viewpoint in Bac Son
For the best panoramic view of Bac Son Valley, Na Lay Peak is the most accessible viewpoint in Bac Son. Located in the center of Bac Son town, it offers sweeping views across the rice valley and surrounding limestone karst mountains.
A staircase of around 1,200 uneven steps leads to the summit, where a small platform near a telecommunications station overlooks the entire Bac Son Valley. The climb takes about 45 minutes, depending on pace, and is best done early in the morning or late afternoon.
Sunrise and sunset at Na Lay Peak are both spectacular, though care should be taken when descending the uneven steps in low light or wet conditions.
Ride through the Tham Khach Archaeological Cave
Tham Khach Cave is one of Bac Son’s most unique attractions, a natural cave around 1 km long with a road running directly through the cave. Riding through Tham Khach Cave by motorbike is one of the most adventure experiences in the area.
The cave is completely dark, so riders must use high-beam and ride slowly through the tunnel. On the far side, Tham Khach Cave opens into a remote agricultural valley used by local farmers, surrounded by the limestone karst landscape of Bac Son.
Tham Khach Cave also has historical significance, as it was used extensively during the war as a storage facilities and war weaponries. Remnants of old buildings remain near the cave entrance, and although it is a dead-end road, the motorbike ride through the cave and hidden valley makes it well worth the detour.
If you ride from Ba Be toward Hanoi, you may choose Lang son and ride across this cave.
Nong Luc Communal House
Located about 8 km south of Bac Son, near Flower Valley, Nong Luc Communal House sits just off the DT241 and is one of the important historical sites in Bac Son.

Today, Nong Luc Communal House remains an important spiritual and cultural center for the local community, and is an easy stop to combine with a visit to Flower Valley and the DT241 route south of Bac Son.
Dong Lam Plateau (Little Mongolia)
Located about 32 km south of Bac Son, near Huu Lien, Dong Lam Plateau is often called “little Mongolia” because of its wide, open grassland landscape surrounded by limestone karst mountains.
During the rainy season, Dong Lam Plateau fills with shallow lakes, while in the dry season it becomes a popular place for picnics, barbecues, and watching local horses roam freely across the plateau. The open scenery creates a striking contrast with the karst mountains around Huu Lien and Bac Son.
Rock Climbing in Huu Lien
For adventure travelers, Yen Thinh Village near Huu Lien has become a recognized rock climbing destination in northern Vietnam. Although climbing equipment is usually arranged in Hanoi, companies such as Viet Climb offer guided climbing experiences and gear rental for Huu Lien climbing routes.
