The karstic landscapes of Phou Hin Poun are the result of two histories which overlap and intertwine more and more: the history of the Earth and that of Men.
In Phou Hin Poun, the influence of human on nature is relatively recent: communities found refuge in this territory and settled there. The populations invested the Phou Hin Poun by cruising the rivers and then cultivated the karstic plains. The forests are still resources for these same local populations who go there to hunt or collect building materials. This relationship between human and natural environments goes beyond the material framework alone. Indeed, legends, beliefs and myths have appeared in contact with the karst. At the origin of these beliefs, karstic sites (such as caves) and relief shapes sculpted in limestone have always served as landmarks for the movement of villagers, troops and military or commercial convoys. Major landforms of the Phou Hin Poun karst, the caves have been very popular, sometimes inhabited.
