Car Hire at Ontario Airport
Ontario International Airport (ONT) serves the Inland Empire, a region east of Los Angeles that includes San Bernardino and Riverside Counties. For travellers heading to Disneyland, Palm Springs, Joshua Tree National Park, or destinations in the eastern Los Angeles metropolitan area, Ontario offers a less congested alternative to Los Angeles International Airport (LAX). This page explains what to expect when collecting a rental car at Ontario Airport, which regional destinations are practical from this location, and what to verify before confirming your booking.
When to Hire a Car at Ontario Airport The Inland Empire is a car-dependent region. Public transport exists but is geared toward commuters rather than visitors, and destinations are spread across a wide geographic area. A rental car is the most practical way to reach theme parks, desert resorts, mountain destinations, and business appointments throughout Riverside and San Bernardino Counties. Consider whether Ontario or LAX better suits your plans. Ontario is closer to Disneyland, Palm Springs, and the San Bernardino Mountains. LAX has more flight options and more rental suppliers, but the airport experience is larger and more complex. For trips focused on the eastern LA metro area or desert destinations, Ontario often saves driving time and airport hassle. Summer temperatures in the Inland Empire can exceed 40 degrees Celsius. Ensure your rental vehicle has adequate air conditioning, and carry water if you are driving to desert or mountain destinations. Winter in the nearby mountains brings snow; chains or four-wheel drive may be required on mountain roads during winter storms.

Airport Rental Car Facility
Ontario Airport has a consolidated rental car facility located near the passenger terminals, accessible by a short shuttle ride or walk depending on the terminal. All major rental companies operate here. The facility is smaller and less crowded than LAX, making the collection process quicker for most travellers. Have your booking confirmation, driver's licence, and credit card in the name of the main driver ready. International visitors should carry their home licence; an International Driving Permit is recommended for licences not in English. Some suppliers require a credit card for the security deposit. Inspect the vehicle with staff and photograph any existing damage before leaving the lot.
Inland Empire Driving Considerations
The road network around Ontario is dominated by freeways. Interstate 10 runs east-west, connecting to Los Angeles in one direction and Palm Springs in the other. Interstate 15 runs north-south, providing access to San Diego and Las Vegas. The California State Route 60 and Route 91 offer additional east-west corridors. Traffic is heaviest during weekday morning and evening commute periods. Allow extra time for congestion when travelling toward Los Angeles or Orange County. Mountain roads to destinations like Big Bear Lake are steep and winding; drive with care, especially in winter conditions.
Plan the handover, price and first drive
The Inland Empire has grown rapidly over the past several decades, transforming from agricultural and citrus-growing land into a major population and logistics centre. Ontario itself is a hub for shipping and warehousing, with the airport supporting significant cargo operations alongside passenger flights.
For visitors, the appeal is in the location. Ontario sits within reach of multiple distinct regions: the beaches and attractions of Orange County, the desert resorts of the Coachella Valley, the mountain recreation of the San Bernardino range, and the urban density of Los Angeles. A rental car makes all of these accessible from a single base.
Summer in the Inland Empire is genuinely hot. Temperatures regularly exceed 35 degrees Celsius and occasionally reach the mid-40s. Air conditioning is not optional. If your rental vehicle's cooling seems weak at collection, request a different car. Desert and mountain destinations can be significantly cooler, so pack layers.
The region's growth has brought diverse dining options. Mexican food is particularly strong throughout the Inland Empire, reflecting the area's demographic history. Korean, Vietnamese, and Middle Eastern restaurants are also well represented in the larger cities. A rental car lets you explore beyond the chain restaurants near the airport.
Check the conditions behind the price
The selected supplier’s terms and booking voucher control the rental. Review them before payment and again before collection.
Total payable price
Compare the full payable amount and inclusions rather than an unsupported daily-price promise.
Deposit and payment card
Confirm the deposit, accepted card type and whose name must appear on the card.
Excess and cover
Read the renter's liability, exclusions and what any optional protection actually changes.
Fuel policy
Know the collection level, return requirement and whether a refuelling charge can apply.
Mileage and territory
Check any distance limit and where the vehicle may be driven.
Extras and return
Price additional drivers, seats, after-hours service and one-way return before payment.
Choose for people, bags and roads
A category normally represents a group of similar cars, not a promise of one exact model.
- Compact: convenient for couples and tighter parking.
- Intermediate: more room for bags and longer journeys.
- Family or SUV category: useful only when the required capacity justifies it.
- Transmission: select automatic explicitly if manual is unsuitable.
Practical planning before departure
Documents and Deposits
A valid driver's licence held for at least one year is required. International visitors should carry their home licence and consider an International Driving Permit. A credit card in the main driver's name is typically required for the security deposit. Some suppliers accept debit cards with additional conditions. Confirm the deposit amount and card policy before booking.
Fuel Policy and Mileage
Full-to-full is standard. Petrol stations are plentiful along the major freeway corridors. Unlimited mileage is typically included, but verify for longer trips. If you are driving to Las Vegas or Phoenix, confirm that your mileage allowance covers the distance.
Insurance and Excess
Basic cover is included, but a substantial excess usually applies. Consider your options for reducing this excess. The booking platform, the rental desk, and standalone travel insurance policies each offer different levels of cover. Read who handles claims and what evidence is required. Photograph the vehicle at collection and return.
Additional Drivers and Extras
Adding a second driver incurs a daily fee, with both drivers meeting age and licence requirements. Child seats, GPS units, and toll transponders should be requested in advance. Automatic transmission is standard in the United States.
Age Requirements
Drivers must typically be at least 21. Those aged 21–24 usually pay a young driver surcharge. Verify any upper age limits with your chosen supplier.
Local access, road and operating conditions can change. Check current signs, your supplier instructions and the linked source before travelling: US National Park Service travel information.
Build a realistic first journey
Ontario to Disneyland and Anaheim
Disneyland Resort in Anaheim lies west of Ontario, accessible via the California State Route 91 or Interstate 10 to Interstate 5. This is one of the most common routes for visitors arriving at Ontario. Traffic on this corridor is heavy during morning rush hour toward Orange County and evening return traffic. Allow extra time during peak periods.
Ontario to Palm Springs and Desert Resorts
Palm Springs and the Coachella Valley lie east of Ontario along Interstate 10. The drive crosses desert terrain and can be extremely hot in summer. Ensure your vehicle's cooling system is functioning properly before departure. Winter brings pleasant temperatures to the desert and is the peak tourist season.
Ontario to San Bernardino Mountains
Big Bear Lake and Lake Arrowhead sit in the San Bernardino Mountains, north of Ontario. Access is via Highway 18 or Highway 330, both steep and winding mountain roads. Winter driving may require snow chains or four-wheel drive; check current conditions and requirements before travelling. Mountain passes can close during heavy snow.
Ontario to Joshua Tree National Park
Joshua Tree National Park lies east of Palm Springs, accessible via Interstate 10 and Highway 62. The park is known for its desert landscapes, rock formations, and stargazing. Summer temperatures are extreme; spring and autumn are the most comfortable seasons for visiting. There is no fuel inside the park, so fill up before entering.
