The Hemet Maze Stone is a prehistoric petroglyph.
 It is just outside Hemet in Reinhardt Canyon, within the Lakeview Mountains, in Riverside County, California.
 On April 16, 1956, it was donated, along with 5.75 acre of land, to Riverside County, by Mr. and Mrs. Rodger E. Miller.
 It is California Historical Landmark No.557.
 The government has installed two perimeter chain link fences around the petroglyph landmark, making direct appreciation, study or an unobstructed picture difficult.
 The surrounding land has been set aside for the protection of native plants and animals (with a warning that the “natural features may be hazardous”), and is at the end of California Avenue to the north of Highway 74 and east of Highway 215, near Hemet, California.
 According to a sign where the road has been blocked off to prevent people from driving closer to the Maze Stone, people with questions can call the Riverside County Parks Open Space Office at 909-245-1212.
