You'll begin by heading east on State Route 22 from Santa Ana, merging onto I-91 East as you leave the urban core behind.

As you travel east from Santa Ana, you'll notice the landscape gradually transition from dense urban development to a more open, suburban setting. The terrain itself is relatively flat through most of Orange County, but you'll encounter some gentle elevation gains as you approach Corona and enter Riverside County. Around the Anaheim area, you're surrounded by commercial districts and residential neighborhoods, but once you pass through the I-91 and I-15 interchange corridor, the scenery opens up considerably with more space between developments.

Corona sits in a valley surrounded by rolling hills and mountain ranges that frame the area beautifully, and as you approach the city, you'll notice these geographical features become more prominent. The Santa Ana Mountains lie to the south and the San Bernardino Mountains to the east, creating a dramatic backdrop to your drive. You'll also pass near several significant Orange County landmarks and the transition between two major county lines, making this route particularly useful for understanding Southern California's regional divisions.

The best time to make this drive is during the cooler months from October through April, when temperatures are mild and the numerous orange groves that still dot the region between the two cities are at their most scenic. Summer months can see heavy traffic, particularly during rush hours (7-10 AM and 4-7 PM on weekdays), and the heat can make the drive feel longer. Winter mornings might bring occasional fog, particularly around the I-91 corridor, so allow extra time if driving very early in the day during these months.
