Cornville and Page Springs are rapidly growing suburban areas that serve as bedroom communities for nearby Sedona and Cottonwood. Both communities are located along Oak Creek, a tributary of the Verde River. Lower Oak Creek has been designated an Important Bird Area by the National Audubon Society. Page Springs hosts a large fish hatchery operated by the Arizona Game and Fish Department. Adjacent to the hatchery are creekside hiking trails and bird-watching areas.
Cornville's best known resident was U.S. Senator and 2008 Republican presidential nominee John McCain. McCain's home in the community, referred to in the media as his "Sedona Cabin," is where he and his running-mate, Alaska governor Sarah Palin, prepared for their debates. On August 25, 2018, McCain died in his home in Cornville.
Cornville has a Greater Cornville Community Association, which meets monthly.
