A majority of Mount San Jacinto State Park and Wilderness is part of the Santa Rosa and San Jacinto Mountains National Monument. From Desert oases to granite peaks, the Santa Rosa and San Jacinto National Monument is a land of contrast with stories of adaptation.
The deeply weathered summit of Mount San Jacinto stands 10,834 feet above sea level, and is the second highest mountain range in Southern California. No more than a two hour drive from either Los Angeles or San Diego, the mountain's magnificent granite peaks, subalpine forests, and fern-bordered mountain meadows offer a unique opportunity to explore and enjoy a scenic, high-country wilderness area. The park offers two drive-in campgrounds near the town of Idyllwild. Most of the park is a designated wilderness area enjoyed by hikers and backpackers.
