Tuilut is a sinkhole found near MZP Puk. It is a large crack on a rocky ground where a stream called Pherpui flows in without any known outlet, which till today remains a mystery, particularly considering the large amount of water that disappears into it during the rainy season. According to the local youth adventure club that has carried out an exploration, the sinkhole has a vertical drop of about 40 ft from the mouth, and then inclined slightly and can be explored up to a length of about 213 metres.
Also situated around Ngentiang village are other noteworthy landmarks: 'Sahlam', an old tree on which 'Human heads were hung', dating back to the days of chief Lalvunga when slain enemies were decapitated and their heads displayed as trophies; 'Lamlung', a large flat rock where in the olden days the villagers used to perform 'Chai' dance with Neihlaia who was said to possess some magical powers including love potion and was feared by all including the chief. There are also beautiful cliffs nearby which are worth exploring and are particularly spectacular during the rainy season when waters cascades down from the numerous gorges.
