Trail Information

Highlights

4S01 Black Mountain is the highest offroad trail, at 7,665 feet, in the San Jacinto Mountains, which is in the San Bernardino National Forest near Idyllwild. Because of its 2,300 foot elevation change over the 12 mile route you will experience a wide range of scenery from the lower scrub and manzanita to the pine, oak and cedar at the top. 4S01 Black Mountain is well know for its camping areas, and is also a rendezvous point for hikers on the Pacific Crest Trail. This trail is also a favorite for practicing your rock climbing skills. 4S01 Black Mountain closes during winter so you should check with the San Jacinto Ranger District as to status. Please respect the animals who call this forest their home, they were here first.

I took this trail yesterday and enjoyed the amazing beauty of this portion of the forest that i don't get to very often. The views are amazing! I seriously was wondering why they gave this trail an intermediate rating, once you get to the "top", and the trail begins to go downhill, it does get a little more "fun". Nothing a Jeep can't handle. Very much worth the trip for the scenery alone, if not for the trail difficulty,

Great trial to escape the heat, it was over 100 in Hemet but 68 at 7,500'. The trail up through waypoint 7 is more like a road and could be driven in the family sedan. Past waypoint 7 was much less busy and more trail-like, it included some mild off-camber, loose rocks, and small steps but still very easy. Chatted with some dual-sport motorcyclists at the end of the trail and a couple F250, crew cab, long bed truck drivers on the way back out, everyone was enjoying the trail. There are some truly spectacular views, great rocks to climb, and beautiful conifer forests. A relaxing drive and lunch in Idyllwild afterward made a great trip.

This was a very peaceful and scenic drive. Scouted a few great yellow post campsites, and stopped many times to enjoy the fantastic views. As others have mentioned, this is an easy trail. Only reason to give it a technical rating of 3 are some ruts towards the end. The first half is a well-maintained dirt road that any vehicle could probably make. The second half you might air down for comfort.

I found this trail to be very good for new offroaders as the first half of the trail is well maintained and traveled by 2wd vehicles to get to some of the lower campsites. It is also one of the most scenic local routes in the area. Although 2wd vehicles can travel the majority of the first half of the trail, I would highly recommend still airing down as it will make more of a smoother ride. Along the way on the lower half of the trail, the road will be asphalted for the switchback turns only. When you reach Fuller Ridge Spur, the trail truly becomes a moderate trail and does require 4wd. In several areas, the trail will become very rutted as well as other areas causing some off-camber. However, I found nothing too difficult. but enough difficulty for new offroaders to get used to and know the capabilities of their vehicles such as in the case of my son-in-law, taking his truck out for the first time. Again, very scenic with several view points and numerous disperse camping areas. This is definitely a trail I will run again.
