Mandshir Khiid to Ulaanbaatar
This approach to Tsetseegün from the south side is the easiest route by far. As you face the monastery, cut over to your right (east) until you get to the stream. Just follow the stream until it nearly disappears and then head north. About three hours’ walking should bring you out over a ridge into a broad boggy meadow, which you’ll have to cross.
