Bak Puk Cave
Bak Puk also known as Tui Lut, is located at Project Veng within the town of Kolasib. With its vertical narrow entrance drawing in rainwater, it is more like a sinkhole. But, the tunnel later forms into wide caverns with awe-inspiring rock formation and deep pools which are yet to be fully explored with proper equipment. Considering the amount of rainwater that it accumulates, it is amazing that it has no known outlet, thus giving rise to a legend that the entire town is on top of an underground lake.
