The Ninh Binh Department of Tourism announced on November 12 that the Trang An Scenic Landscape Complex had been included in the third list of 100 IUGS Geological Heritage Sites worldwide, released by the International Union of Geological Sciences (IUGS).

Trang An Tropical Karst in Ninh Binh Province, Vietnam, was designated Site No. 283 under the category of geomorphology and active geological processes.

The recognition further strengthens the standing of Vietnam's natural heritage in the global geological science community.

According to the IUGS, Trang An is one of the world's foremost examples of tropical karst landscapes that were once submerged and shaped by the sea but are now exposed on land.

Its limestone mountains, extensive cave systems, valleys and traces of ancient marine environments form a remarkable natural geological museum, preserving evidence of more than 250 million years of Earth's geological evolution.

The IUGS designation in 2026 not only recognizes Trang An's outstanding geological significance but also acknowledges efforts to conserve and promote its heritage values, develop sustainable tourism and create livelihoods for local communities.

Trang An previously achieved international recognition in 2014 when UNESCO inscribed it as a World Cultural and Natural Heritage Site, the first mixed World Heritage property in Vietnam and Southeast Asia.

In 2025, Tripadvisor also ranked Trang An among the top 1% of destinations worldwide.

In the third edition of the IUGS Geological Heritage Sites list for 2026, Trang An is featured on pages 230–231 alongside internationally renowned geological landmarks such as Mount Fuji in Japan, the Norwegian fjords, Mount Aconcagua in Argentina and the Chocolate Hills in the Philippines.

The announcement was made during an event held from November 4 to 8 in Monchique, Portugal.
