Ontario is in San Bernardino County and the Southern California region of California, more than 35 miles east of Los Angeles. From a traveler's perspective, Ontario is noteworthy mainly as the home of a large mall and the Ontario International Airport, a less crowded alternative to LAX and the main airport serving the Inland Empire.

Get in

By plane

1 LA/Ontario International Airport (ONT IATA), is the area's regional airport for commercial flights serving the Inland Empire in the eastern part of the greater Los Angeles area and the adjacent desert locales. It is less busier and quieter than LAX. The airport is located 2 mi (3.2 km) east of Ontario's Business District off of I-10 at the "Archibald Ave/Ontario Airport" (Exit #55/55A) and the "Haven Ave" (Exit #56) exits. Currently there are only two terminals for commercial flights numbered 2 & 4:

  • Terminal 1: The 2 USO is in the (old) Terminal 1 building for military personnel transiting into or out of the area and the 3 International arrivals terminal is in a separate building for Aeromexico & Volaris arrivals from Mexico. There is a free shuttle bus from the old terminal 1 and international arrivals to Terminal 2 & 4.
  • 4 Terminal 2: Alaska Airlines/Horizon Air (Gates 205 & 206), Aeromexico (Departures), Delta/Delta Connection (Gate 208), United/United Express (Gates 201-203), Volaris (Departures)
  • 5 Terminal 4: American Airlines (Gates 408 & 410) and Southwest (Gates 401-407)
  • 6 Car Rental Terminal ... located at 3450 E Airport Dr in the NE Corner of the airport grounds at E Airport Dr & N Haven. From Terminals 2 & 4 there is a frequent and free shuttle bus going over to the consolidated car rental terminal to pick up a rental car. If renting from Advantage, Payless, Fox or another 'off airport' company they send their shuttle to pick up customers at the consolidated car rental terminal instead of the airline terminals. For a better rate on car rentals it is best to shop around and reserve a car online or over the phone PRIOR to arrival. Having a private car is the BEST way to get around locally for going out to remote locales such as Joshua Tree.

By car

Ontario is located along Interstate 10 (I-10), west of the Interstate 10 & 15 junction, approximately 37 mi east of Los Angeles (39 min), 24 mi (25 min) west of San Bernardino, 71 mi (1 hr) west of Palm Springs,and 114 mi (2hr 14min) northeast of San Diego (off of Interstate 15):

  • From Los Angeles, simply take I-10 (San Bernardino Fwy) East (or west if coming from San Bernardino or Palm Springs). Ontario is accessed from exits #49 ("Central Ave") through #59 ("Etiwanda Ave") along I-10. Ontario does not have a clearly defined downtown except the closest thing would be the neighborhood NE of the intersection of N Euclid Ave & E Holt as that is where city hall and other city government function is located at. To get there, exit off at the N Euclid Ave (CA-83)/Upland off ramp at Exit 51 and go south along N Euclid Ave To E Holt. Likewise one can also go east on CA-Hwy 60 which goes along the south side of town. From CA-Hwy 60 (Pomona Fwy) Ontario is accessed from Exits #34 ("Mountain Ave") through Exit #41 ("Milliken Ave")
  • From San Diego take I-15 North until CA-HWY 60 at exit 106 or the next one up at I-10 at Exit #109. Go west on CA-60 or I-10 to get to Ontario

By train

Confusingly, Ontario has two train stations. Firstly, there's 7 East Ontario station which is served daily by the Metrolink Riverside Line, connecting with Union Station in downtown Los Angeles. Then there's 8 Ontario Amtrak which sees trains just three times a week, when the Sunset Limited between Los Angeles and New Orleans (with through-cars towards Chicago on the Texas Eagle) make a shot stop there.

By bus
