Trail Information


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.

Trail is open. Some deep ruts caused by rain, but my Tacoma Sport 2WD didn't bottom out.

One of the most beautiful trails in the area in my opinion. This is a really easy trail to all the camp sites which all had amazing views. Once your past the camp sites is when you get to start wheeling and it turns into a 3. Did it in my zj with 4” lift and 31s.
