Wispy clouds cast a mist over one of Mau Son peaks at more than one kilometer above sea level in Lang Son Province, which borders China and 180 kilometers to the northeast of Hanoi. Each season, including the cloud hunting season from August to March, casts Mau Son in a unique light. Adding to the scenic diversity are its inhabitants, including the Dao, Tay and Nung ethnic communities.

The photographs are part of a series by Lang Son resident Bui Vinh Thuan.

The Mau Son mountain range stretches from Mau Son Commune in Loc Binh District to Cong Son Commune in Cao Loc District. A part of the mountain is on the China border, marked by the Chi Ma border gate at the bottom.

Mau Son consists of nearly 80 peaks. Phia Po (also known as Cong Son Mountain) is the highest of them at 1,541 m, followed by Phia Se (also known as Mau Son) at 1,520 m tall and Tra Ky at 1,180 m.

 

Visitors to Mau Son during April and May every year will have the chance to see locals plant rice on terraced fields next to anise forests. Besides rice, locals use the fields to plant corn in early summer, presenting a completely different look.

 

A 7-meter waterfall in Mau Son.

There are over 10 large streams that flow across the northern and southern slopes, creating many waterfalls with clear water all year round. Travelers can enjoy themselves outdoor camping, swimming by waterfalls and enjoying the sight of hydrangeas, a flower species that blooms profusely every summer.

The mountain is submerged in the golden color during rice harvest season during July and August.

The mountains turn golden as the rice crop ripens in July-August and are a sight that draws thousands of visitors every year. The different shades of green and yellow formed by the fields and surrounding trees and shrubbery, not to mention the brown and other hues of the farmer’s huts are a visual delight and a photographer’s dream.

Thuan said that the place gets packed with tourists in summer because there are many entertaining events organized at this time, including folk games and folk music concerts.

Although the snow season helps this place attracts many tourists, the icy weather can cause damages to local crobs.
