Stretching over the area of Mau Long commune, Yen Minh district and Sung Trai commune, Dong Van district, the cave was discovered by scientists in 2010 and is considered the most beautiful cave to be unearthed in Ha Giang so far.
The cave was formed in limestone, which is a common geological tendency across the Dong Van Krast Plateau in Ha Giang—a UNESCO-recognised Geo-Park.
The entrance to the cave, 30 metres in width, is covered with many valuable timbers. The inside of the cave amazes visitors with many stunning stalactites in various shapes and colours, which have been formed over thousands of years.
According to Secretary of the Yen Minh district Party Committee, Hoang Van Vinh, the district authorities have taken measures to safeguard the pristine beauty of the cave and raise public awareness of visitors and ethnic minority groups on protecting its surrounding ecological environment.
Efforts have also been made to advertise the image of the cave, making it an attractive destination for tourists to Ha Giang, he said.
