It is the fourth UNESCO Global Geopark in Vietnam, after Dong Van Karst Plateau (recognised in 2010), Non Nuoc Cao Bang Geopark in 2018 and Dak Nong Geopark in 2020.

Lang Son Geopark was voted as a UNESCO Global Geopark during the 8th Asia–Pacific Geoparks Network Symposium in Cao Bang province, Vietnam, last September. The designation was approved by the UNESCO Global Geoparks Council after a thorough evaluation of the site's geological significance, conservation efforts, and community involvement.

The geopark covers 4,842.58 km², spanning 8 administrative units and accounting for 58% of the province's area and 78% of its population. It preserves important geological evidence of Earth's history over hundreds of millions of years, including records of ancient seas, volcanic activity, and ecosystem development.

The geopark features archaeological sites with traces of human presence dating back 30,000 to 470,000 years, showcasing the deep-rooted human history of the area.

It is home to Tay and Nung ethnic communities with rich traditions. It also hosts landmarks like Bac Le Temple, a key site in the Mother Goddess worship practice, which is inscribed by UNESCO as Intangible Cultural Heritage of Humanity.

With around 200 caves and scenic waterfalls, Lang Son Geopark has strong potential for eco-tourism and adventure tourism development.

The designation of Lang Son Geopark as a UNESCO Global Geopark not only affirms its unique geological and cultural values but also offers new opportunities for sustainable tourism development, heritage conservation, and international cooperation

It is a major milestone that boosts Lang Son's visibility on the global tourism map and contributes to Vietnam's reputation for natural and cultural richness.

Sustainable ecotourism the main goal of Lang Son Global Geopark

The northern mountainous province of Lang Son is taking measures to preserve and promote the ecotourism value and potential of the Lang Son Global Geopark, recognised by UNESCO in September 2024.
