A 60ft vertical drop and 5ft wide crevice were exposed in Mawlyngbna village back in 2013 by a small group of adventure enthusiasts with the help of the local youths of the area. Previously, the place was used as a dumping ground for bay leaf branches whereas the top of the crevice was used as a roasting and nursery area. Mawlyngbna village has countless of these crevices but this was later monetized and developed as a tourism spot. Popularly known as “Mawsiangjroi” in Mawlyngbna village, the crevice acts as a shelter for many local bat and bird species. When darkness falls giant tarantulas and huntsman spiders can be seen crawling up the vertical walls looking for insects to feed on. There are three sections to the crevice, with man-made ladders connecting one section to the other. An array of tree roots falling from the top of the crevice makes it look like a world from another dimension with a thin line of visible light striking the crevice. Stalactite and stalagmite formations can also be seen in the upper chambers of the crevice. A small crawling passage is another section that entices travellers to venture into the crevice. The crevice is a fun yet unearthly hike to the inside.
Tourists can enjoy the cool breeze blowing from the top, and see beautiful life forms, and what makes it more fun when one is not arachnophobic is to see the giant spiders. On exiting the crevice, one can observe the vast and flat rocky surface with a sight of the Bangladeshi plains.
