Black Gulch 4WD trail at 11 miles long drops you about 3000 feet in the dense Sequoia National Forest from its start at Rancheria Road, eventually leading to paved roads and the shores of Lake Isabella. The road has challenging sections that are well-marked, allowing us to bypass these difficult portions. The trail is narrow and heavily rutted and will take maneuvering to enable another vehicle to bypass. We found no camping along the trail but did camp near the trailhead on Rancheria Road at Evan Flats.
