Aside from the many colorful stories (some true) and urban legends about Black Star Canyon and surrounding areas, Black Star is essentially just a fire road up the side of the Santa Ana Mountains. However it does lead to other trails higher up in the mountains.
Review: Nothing too exciting riding-wise but a long fireroad ascent/descent with some single track options near the top. Otherwise, it offers very nice scenery and serves as one of the easier access roads to main divide to explore other trails in the Santa Anas.
Review: Happened upon this trail by accident while I was visiting California. Probably not a good idea if your from Florida and not used to extended climbs. I made it about 3.5 to 4 miles into the climb before I turned around and enjoyed the downhill. It was definitely a workout. Probably a great place to train up your climbing skills.
Review: Good little hill climb that leads to some better trails up off Main Divide. It is the easiest way up to Main Divide and over the Santa Anas. Good trail to take newer riders on who are looking for a little more of a challenge and a good introduction to longer climbs.
