Ontario sits in California's Inland Empire, an easy base for reaching Los Angeles, the San Gabriel Mountains and the Mojave beyond. The city itself is low-slung and spread out, built around wide boulevards, big-box retail and the sprawling Ontario Mills mall. February brings mild, dry days when the mountains to the north often carry a cap of snow. Rent a car here, as walking between places is rarely practical.
