It rises in two forks of similar length and size, West Fork City Creek and East Fork City Creek, in the San Bernardino National Forest. Both forks begin on the crest of the San Bernardino Mountains. The West Fork rises near Crest Summit south of the unincorporated community of Crest Park, at about 5,400 feet (1,600 m). It flows south then southeast and finally south again through multiple gorges, picking up several unnamed tributaries. The East Fork begins in a fan-shaped group of gulches south of Heaps Peak and Mount Sorenson, at about 6,000 feet (1,800 m). From there it runs south-southwest in a canyon past Fredalba, receiving Schenk Creek from the left near the mouth. The West Fork is about 4 miles (6.4 km) long; the East Fork stretches roughly 3 miles (4.8 km).
The two forks combine in a steep chasm just downstream of where the West Fork passes under a bridge of California State Route 330, also known as City Creek road. The main stem flows south in a thousand-foot-deep gorge between McKinley and Harrison Mountains, rapidly dropping to the plains near Highland, where most of its flow is diverted into canals for municipal and agricultural usage. Downstream of the diversions the creek fans out into alluvial deposits. Cook, Bledsoe and Elder Gulches as well as Plunge Creek all enter from the left as the creek flows along the east side of Highland in a wide flood control channel. It joins the Santa Ana River to the southeast of San Bernardino International Airport.
