1. What Makes Thang Hen  Special?

Located within the Non Nuoc Cao Bang UNESCO Global Geopark, Thang Hen  is a natural freshwater lake surrounded by dense forests and karst mountains. Unlike many other lakes, Thang Hen never fully dries — even during the hottest months.

Its water shines a deep shade of emerald year-round, reflecting the trees, the sky, and the towering cliffs around it. At sunrise, morning mist drifts across the lake like a soft blanket, making the landscape feel magical and untouched.

The region is home to 36 interconnected lakes, but Thang Hen is the largest and most beautiful among them.

2. The Legend Behind Thang Hen 

According to local Tày folklore, the lake was formed the tears of a talented man who fell in love with a girl the mountains. Their love story, filled with happiness and heartbreak, became part of the soul of this land.

Even today, locals say the lake’s calm surface carries the emotions of that ancient tale — gentle, deep, and eternal.
