Black Mountain Yellow Post Sites
These six remote camping sites offer isolated scenic locations ideal for tent and car camping or a relaxing picnic far from the crowds. Some have great views of San Jacinto Mountain and the San Gorgonio Pass area. These sites are first-come, first-served and are generally open in the late spring, summer, and fall months. During winter, Black Mountain Road closes due to snow accumulation, but it is still possible to hike, snowshoe or cross-country ski to these sites. Other than a pit for campfires and a picnic table, these sites do NOT contain the amenities found at developed campgrounds. There is no water, no restrooms, and no trash containers. Please pack it in - pack it out! Campfire permits are required for any type of fire use - campfires, charcoal BBQ`s, or gas stoves. Campfires and charcoal BBQ’s may not be allowed certain times of the year. See "Current Conditions" box below. Where are the Sites? These Yellow Post Sites are reached via forest road 4S01 off of Hwy 243 north of Idyllwild and south of Banning. This is a dirt road and is not suitable for trailers or RV’s. High-clearance vehicles are recommended.
