Plan a trip to Ontario

Named for the Canadian hometown of two 19th century engineers who first developed the area for urban living, Ontario is known as the "gateway to southern California." Resting 35 miles east of downtown Los Angeles, popular attractions like Disneyland and the mountain retreats of Lake Arrowhead and Big Bear are all within reach of Ontario. In the city, walk among tall palm trees and emerald lawns as you sample delicious olives at the Graber Olive House, founded in 1894. Take a spin the rides at Scandia Amusement Park, and stop in at the local Museum of History and Art for regional discoveries, like the real story of travel on the legendary Route 66.
