Today will be a long travel day to the Ongiin Khiid. Ongiin Khiid refers to two ruined monasteries: Bari Lam Khiid, which was built in 1810 on the north bank of the river near the tourist ger camps, and Khutagt Lam Khiid, which was built in 1760 on the south side of the river and is only accessible when the water is low or frozen over. Once one of the largest monasteries in Mongolia, the complex was destroyed in 1937 as part of a communist purge. Since 1990, a small but growing contingent of monks has resettled amid the ruins, gradually restoring the ancient site. Spend the day exploring the ruins and visit the small museum, then return to the ger camp in the afternoon.
