The Modjeska Peak hike is challenging – long, steep, and sometimes primitive. The hike climbs to the second highest point in Orange County, Modjeska Peak. Modjeska Peak, at 5,499 feet, is the lower peak in Saddleback Mountain. The highest peak (and other peak in Saddleback Mountain) is Santiago Peak. The actual summit is undeveloped and much nicer than nearby Santiago Peak. This is a challenging hike. Don’t try this hike without a good level of fitness.
