The delegation has visited 26 out of the 38 attractions across four tourism routes of Lang Son Geopark.

Covering more than 4,800 sq.km. across eight districts, Lang Son Geopark is one of the largest of its kind in Vietnam and boasts a number of unique values. It is home to a rich diversity of fossils dating back as far as 500 million years, many of which indicate this province was under the sea in the past.

The park is also endowed with many renowned landscapes such as the low mountain ranges surrounding valleys and villages in Huu Lung district, or the caves like Tham Khuyen in Binh Gia district that accommodated prehistoric humans.

It houses a number of temples dedicated to the gods in the worship of Mother Goddesses – an intangible cultural heritage of humanity.
