Kyet Cave, also known as Yarsu Ku, is located 15 km away from Loikaw. It is a natural limestone cave. Kyet means evil spirits or ghosts. The cave is called Kyet Cave because 2-15 feet long wooden coffins were found in the caves. Some coffins can be found 20-30 feet above the ground on the wall of the cave. It is said the human bones were found 70 years ago. But no human bones nowadays, only decayed coffins. There is a monastery outside the cave. The cave was lit upto 1500 feet from the enterence, by generator run by the monastery. You could ask the monk to run the generator while you were in the cave, by donating money for gas to run the generator. Or you just take your torch and explore the cave. (P.S – this experience was two years ago.)
