Tham Kong Lo, Natural cave system in Kounkham District, Laos.
The cave extends 7.5 kilometers through limestone mountains, featuring a navigable river passage that reaches heights of 100 meters in certain sections.
Seven local men conducted the initial exploration of the cave after observing rice seedlings floating out, spending three days traversing the underground passages.
The Nam Hin Bun River flowing through the cave connects two separate villages, creating a waterway transportation system for local communities.
Visitors require three separate entrance fees: one for Phu Hin Bun National Park, another for the cave access, and a third for the boat tour.
The underground river journey involves a 40-minute boat ride through complete darkness, with stops to examine geological formations along the passage.
