By train: The Metrolink Inland Empire/Orange County Line stops at Rancho Cucamonga station, connecting directly to Los Angeles Union Station in about 70 minutes and to San Bernardino and Riverside. It is the most practical public transport option from downtown LA. The station is off Milliken Avenue, near Victoria Gardens.
By air: Ontario International Airport (ONT) is the closest airport, about 6 miles southwest. It handles flights to most major US hubs on American, Southwest, United, Alaska, and others, with far less congestion than LAX. A taxi or rideshare from ONT to central Rancho Cucamonga takes 15–20 minutes. LAX is 50–60 miles west; allow 90 minutes to two hours in traffic.
By car: Rancho Cucamonga straddles the I-10 (San Bernardino Freeway) and SR-210 (Foothill Freeway). From downtown Los Angeles take I-10 east to the Milliken Avenue or Haven Avenue exits. From San Diego take I-15 north to Foothill Boulevard. Parking is easy and free throughout the city.
By bus: Omnitrans operates regional bus service in the Inland Empire; local stops connect to the Metrolink station and Victoria Gardens. Greyhound serves San Bernardino, the nearest intercity bus hub.
