Ontario sits in California's Inland Empire, an easy base east of Los Angeles with the San Gabriel Mountains rising to the north. August here is hot and dry, so days lean toward air-conditioned malls, the Ontario Mills outlets, and quiet suburban streets rather than sightseeing marathons. It works best as a practical landing point: pick up a car, and Palm Springs, Joshua Tree, and the coast are all within reach.
