The start of this trail is just outside of Aji Spa. It is an out-and-back trail that is approximately 2.5 miles long. I runs along Wild Horse Pass Blvd, which it crosses several times.
It's an easy trail, without a lot of elevation changes, but don't forget to bring along some water, as it can get incredibly hot in the summer with no shade anywhere along the trail.
Also the last time I was out there, I did see a coyote that was about 50 yards away from me.
