Ontario sits in the Inland Empire of Southern California, a city of wide avenues, historic citrus roots, and one of the region's busiest airports. Euclid Avenue, a broad boulevard lined with pepper trees, runs through the city as part of historic Route 66, and the Ontario Town Square offers a farmers market and concerts. Ontario International Airport connects the region to the country, and Ontario Mills, one of the largest outlet malls in California, draws shoppers from across the Inland Empire. The Graber Olive House, a family olive business since the 1800s, still operates in the city.
