Santiago Peak is the southern mountain of Orange County's Saddleback formation. It is the highest and most prominent peak of both the Santa Ana Mountains and Orange County, and also marks a border point with Riverside County. The top of it is covered with many microwave and telecommunication antennas. It is named for Santiago Creek, which begins on its southwestern flank.
