County Highway S-2 travels from the deserts of Imperial and San Diego County to the mountains. A good portion of the highway travels along the same route that was used from 1700s to get into California’s interior, and was one of the major routes to California during the gold rush of 1849.

The S-2 goes from Ocotillo in the south to Highway 79 near Warner Springs in the north, and travels through Anza Borrego State Park. Along the way there is beautiful scenery, historic stagecoach stations, ranches that hosted troops in the Mexican-American War, and a path through stone that was carved by hand. It is a great day trip and one of the best drives in San Diego County.

The S-2 follows a lot of the same path as the Southern Emigrant Trail, The Butterfield Overland Stage Coach, and the trail taken by General Stephen Watts Kearny and the Mormon Battalion during the Mexican American War.
