Ontario, California, is best known for its airport, one of the busiest cargo hubs in the country, and for being a logistics center of the Inland Empire. About 187,000 people live here, about 40 miles east of Los Angeles. The city is more than warehouses: its historic downtown along Euclid Avenue has old trees, a museum and a small-town feel. Visitors often come for events at Toyota Arena, or to shop at Ontario Mills, and the Christmas on Euclid celebrations draw crowds. Route 66 runs through town, and Guasti Village and Old World Village have a few wineries and casual restaurants. Ontario Ranch, on the south side, is a huge new development with modern homes and parks.
Housing is expensive, though it costs less than coastal Southern California. Crime is moderate for the region, with vehicle theft and break-ins the main issue, especially in older areas near Holt and Mission Boulevards. The bigger everyday concern is air quality: this area has some of the worst ozone and particulate levels in the country, and summers are hot, often above 100 degrees.

Safety overview
Crime is moderate for the region, with vehicle theft and car break-ins the main visitor risk (approximate; exact 2024 rates not retrieved). Hospitals: San Antonio Regional Hospital (Upland), Kaiser Permanente Ontario Medical Center, Arrowhead Regional Medical Center in Colton (trauma). Hazards: hot summers (often 100F+), Santa Ana wind and foothill fire smoke, some of the worst ozone and particulate levels in the US, and Cucamonga and San Andreas fault earthquake risk
Local notes
Specific places where extra care is worthwhile, especially at night. Most visits are trouble-free.
Some older areas south and west of Holt Boulevard and along the Mission Boulevard corridors near the older core have more property and vehicle crime; use ordinary caution at night. Downtown Euclid Avenue, Ontario Mills, the Convention Center and Ontario Ranch are generally comfortable for visitors
Times marked “est.” are estimates: drives use typical road distances at highway speeds, and train or bus times assume both cities have service. Always check a route planner and timetables before you travel.
