In the cool autumn weather, flocks of white storks have returned to Thac Ba Lake (Yen Binh district, Yen Bai province), creating a stunning scene amidst the pristine and peaceful landscape, captivating all who gaze upon it.

Thac Ba Lake covers over 23,000 hectares, with more than 19,000 hectares of water and 1,300 large and small islands. It is often referred to as the "Ha Long Bay in the mountains" and is a well-known tourist destination in Yen Bai province.

Particularly in autumn and spring, flocks of migratory birds, including white storks, return to Thac Ba Lake to settle. This is a testament to the area’s successful nature conservation efforts and its clean, fresh atmosphere.
