The trailhead is reached by turning east off Highway 38 to Forest Falls. Continue through Forest Falls to the top end (east end) of the picnic area at the end of the road (6,080′).
The Vivian Creek Trail is the shortest and the steepest route to the summit of Mt. San Gorgonio. One and two-tenths miles from the trailhead is Vivian Creek Camp (7,100′). Campsites are located upslope to the right of the trail after reaching the stream: one is halfway up the slope, and the other is at the top of the slope (no camping within 200 feet of the trail or creek).
One and three-tenths miles from Vivian Creek Camp is Halfway Camp (8,100′). Water is obtained from the creek 200 yards before camp. Two and three-tenths miles further is High Creek Camp (water available – 9,200′). The summit of San Gorgonio (11,499′) is 3 miles beyond High Creek. The upper end of this trail offers outstanding views of Yucaipa Ridge and Galena Peak, as well as sweeping panoramic views from the top of Mt. San Gorgonio. After the South Fork Trail, this is the second most used trail in the Wilderness.
