Hinboun Geopark, 863 km², located in Khammouane Province in central Laos, showcases spectacular karst landscapes shaped over millennia by water erosion. Deep valleys, canyons, rugged plateaus and vast cave systems form a dramatic natural fortress that preserves rich biodiversity. The Geopark takes its name from Nam Hinboun, whose name can be translated as “Limestone River”, directly referring to the dominant calcareous geology that structures the entire territory. This territory has been inhabited since prehistoric times, creating a strong historical, cultural and spiritual relationship between karst landscapes and local communities.

The karst of Hinboun Geopark is characterized by cone karst (fengcong), limestone peaks rising hundreds of meters above fertile plains, extended underground by impressive cave networks crossed by seasonal rivers. These caves have long served as shelters, sacred places and vital water reserves.

The Hinboun River, the backbone of the area, also supports agriculture and settlement, shaping a living landscape of rice fields, gardens and villages.

Today, the Geopark promotes community-based governance, scientific research and sustainable nature tourism, aiming to protect heritage while fostering inclusive local development, paving the way for the recognition of the first UNESCO Global Geopark in Laos.
