Mount Mau Son, Mountain range in Lang Son Province, Vietnam.
Mount Mau Son is a mountain range in Lang Son Province rising to about 1600 meters, with stone houses and buildings scattered across its slopes. Dense forests blanket the terrain, creating green hillsides throughout the area.
During French colonial times, the mountain shifted from serving as a military position to becoming a retreat for colonial settlers. The stone buildings visible today were built during this period and remain scattered across the slopes.
The Dao people live in villages around the mountain, maintaining their traditional practices in daily life and agriculture. You can see their distinctive houses and clothing styles as you walk through the settlements.
The mountain sits roughly 30 kilometers northeast of Lang Son city and is accessible by car, motorcycle, or organized tours. The winding roads climb steadily, so wear appropriate footwear and bring weatherproof clothing for changing conditions.
Snow occasionally falls during winter months when temperatures drop below freezing, an unusual sight in tropical Vietnam. This rare event transforms the landscape and draws visitors seeking to experience cold weather in an unexpected setting.
