The Ontario Museum of History and Art aims to expand the community's knowledge of local culture through educational programs, exhibits and special events. The museum exhibits in detail, the life and people of the Inland Empire and the docents organize various outreach programs and field trips throughout the year. One of the highlights during Autumn is the Dia de los Muertos festival, when local artists showcase the macabre through painting, sculpture and crafts. Every year the event draws in thousands over the Halloween season.

If you ever wanted to learn about the history of Ontario, Upland, Montclair or the bizarrely named Rancho Cucamonga, then you have come to the right place. When it was established in 1965, the museum was named the Chaffee Communities Cultural Center after its affiliation with Inland Empire businessmen, William and George Chaffee. In 1997, the name changed to honor local benefactor Ada Cooper, a woman who made a philanthropic donation to the center. Inside, visitors will find exhibits, objects and documents that highlight the development and lives of people in this Southern California region. Moreover, the museum also houses an auditorium for performances, talks, workshops and concerts.

Wally Parks was a larger than life character who established what is today the largest organization for motorsports in the world, the National Hot Rod Association. This museum presents the man behind the sport, memorabilia, artifacts and actual vehicles in a modern building that chronicles the history of the sport, from its inception in 1951 to the present-day. It's the ultimate museum for the race fan, where guests can learn more about their favorite drivers, see some cars and find out what's behind all those vehicles with names like 'Funny Car', 'Alcohol Dragster' and 'Super Stock'.
