Cleghorn Ridge is normally an easy trail that can be done in a 2WD truck with decent clearance. With the snow and ice present 4WD and a good tire would be a wise choice. There are many optional side roads that are of moderate and extreme difficulty that I opted not to take on this trip. The views of the surrounding area are astounding and this trail is a lot of fun with some snow on it. This trail can be reached from the Cleghorn Road exit on I-15 a few miles south of Cajon Junction.
Unlike going to the trails in Big Bear, you won’t have to go through highways filled with morons who decided not to get snow tires or bring chains/cables along with them. Enjoy!
