Holy Jim Trail

Route Profile • Holy Jim Trail
Holy Jim Trail is named after James Smith, a beekeeper in the late 19th century.
The hike starts in Trabuco Canyon (dirt road). Half of a mile to the trailhead is paved. Holy Jim Trail crosses Holy Jim Creek several times, then it forks. The right trail leads to Holy Jim Falls for a quarter of a mile, the left trail leads up to Main Divide Road for three miles.
Turning left, Main Divide Road leads up to the summit. Turning right for less than half of a mile, Upper Holy Jim Trail serves as shortcut and offers views of Mount San Gorgonio and Mount San Jacinto. It rejoins Main Divide Road after less than a mile, which leads up to the summit for two miles.
