Erdenedalai sum is the second most populous sum of Dundgovi Province after Saintsagaan. Gimpil Darjaalan Khiid is a sightworthy monastery in the town of Erdenedalai, the administration center of the sum. The monastery was built at the end of the 18th century, and about 500 monks lived there. In 1937, it was one of the very few monasteries and temples which were not destroyed under the rule of Chorloogiin Choibalsan, but the monastery was closed and used as a store house thereafter. In 1990, it was reopened. The current Dalai Lama visited it in 1992.
