Homolovi, a Hopi word meaning "place of the little hills", features a cluster of some 300 archaeological sites including several separate pueblo ruins built by various prehistoric peoples from 1250 - 1400 A.D. The park serves as a center of research for tribal migration of that time period and while archaeologists study the area and confer with the Hopi to unravel area history, Arizona State Parks provided an opportunity for visitors to personally experience two of the seven ruins.

Most visited is the largest, Homolovi II, an excavated site with about 1,200 rooms, 40 kivas or underground ceremonial chambers, clusters of pit houses, and three large plazas. Petroglyphs can be found along certain sections of the nearby Tsu'vo trail.
