Trang An is the only mixed UNESCO World Heritage site in Southeast Asia, recognized for both cultural and natural values.
Trang An is a UNESCO World Heritage landscape complex characterized by a network of karst peaks and flooded caves accessible primarily by traditional rowboat. The site features three distinct tour routes that navigate through limestone grottos and past ancient temples. It is situated within the Hoa Lu ancient capital region, offering historical context alongside geological formations. The boat tours typically include stops at sites such as the Vu Lam Palace and various film set locations. The ecosystem supports significant biodiversity within its submerged forest environment. It serves as a central hub for eco-tourism in the Ninh Binh province.

Bring a hat and sunglasses as there is minimal shade during the multi-hour boat journey.
Keep a small tip ready for the rower, as this is standard local custom for the physical labor involved.
Wear sunscreen and bring a water bottle, as the reflection of the sun on the water increases UV exposure.
Avoid visiting during the peak Tet holiday period, when crowds can lead to multi-hour wait times for boats.
Modest clothing is required to enter religious sites on the route; shoulders and knees should be covered.
