Thang Hen Lake – The Emerald Jewel of Cao Bang’s Mountains

Deep inside the Non Nuoc Cao Bang UNESCO Geopark lies a hidden treasure many travelers overlook: Thang Hen. With emerald water, limestone mountains, and peaceful ethnic villages, the lake is one of northern Vietnam’s most enchanting natural wonders.

1. What Makes Thang Hen Lake So Special?

Unlike many seasonal lakes, Thang Hen stays full year-round, even during the hottest months. It sits among lush forests and jagged karst peaks, creating a landscape that feels untouched and timeless.

On early mornings, a layer of mist drifts across the water, turning the lake a quiet, dreamlike world where mountains float above the surface.

Thang Hen is also connected to 35 smaller lakes, forming a rare natural lake system found only in Cao Bang.

2. The Legend of Thang Hen

According to Tày folklore, the lake was born a heartbreaking love story between a young man and a mountain girl. Their longing and sorrow formed the shape of the lake — deep, calm, and eternal.

Today, locals believe that the lake’s stillness holds the emotions of that ancient tale, giving Thang Hen a poetic and spiritual beauty.
