Agui is the Mongolian word for "cave." There are five natural caves in the barrancas surrounding the temple, namely the Agui Cave, Shengle Jingang Cave, Park Main Cave, Water-curtain Cave and the Buddha Protection Cave.

Agui Temple is famous for its oddity, loneliness, height and steepness. There's a divine fountain with a daily gushing volume of 110 tons, and the waters are used for drinking and bathing. Such desert plants as Caragana microphylla Lam, Opuntia vulgaris Mill and Haloxyon ammodendron grow on the alluvial fans in front of the mountain, and the fans are included in the natural forest protection area by the government of the autonomous region.

Such places of interests as the Yinshan rock painting group, Great Wall of the Qin Dynasty (221-207 B.C.), ancient tomb of the Han Dynasty (206 B.C.-220 A.D.), Jilusai, Hongyang Cave and Fairy Pool are located along the foot of the mountain.
