Cave
Tham Lot Se Bang Fai
The most impressive, and yet least visited, cave in Khammuan is the amazing Tham Lot Se Bang Fai. Located in Hin Namno NPA, the cave results from the Se Bang Fai river plunging 6.5km through a limestone mountain, leaving an underground trail of immense caverns, impressive rock formations, rapids and waterfalls that have been seen by only a handful of visitors.
