Thanh Thuy Lake is located in front of the Khai Tam Gate. Originally, it was a small lake. Historically, it was the gathering place of water from the Giai Oan valley, and now it has been restored and developed into a lake. The clear waters of the lake have earned it the name Thanh Thuy Lake (Clear Water Lake).

At present, Thanh Thủy Lake enhances the landscape, adding to the picturesque scenery of the area, creating a cool and harmonious ecological environment that is favorable for feng shui. In the future, the lake may serve as a venue for cultural exchanges and art performances, utilizing the lake’s surface to entertain visitors to Yen Tu.

• On the shore of the lake, there is an electric vehicle station that transports guests from here to the Ha Kieu station, known as Thanh Thuy Bus Station.

In the future, the lake could be used as a site for artistic performances on the water, enriching the experience of visitors to Yen Tu.
