The hook
A rough dirt road into the Santa Ana Mountains ends at a trail to a hidden waterfall named for a foul-mouthed beekeeper the mapmakers cleaned up.
01Why it's worth it
Holy Jim Canyon was settled in the 1800s by beekeepers and woodcutters, one of whom, James Smith, cursed so much that neighbors called him "Cussin' Jim." When prim government surveyors mapped the canyon they refused to write that down and renamed him Holy Jim, which is the name that stuck to the canyon and the falls. The hike is the draw: a shaded trail that crosses and recrosses the creek to a twenty-foot waterfall in a fern-lined grotto, best after winter rain. There's a darker footnote too, the last wild grizzly bear in this range was killed at the mouth of the canyon in 1907, robbing beehives. It feels far from the suburbs even though it isn't.
02How to experience it
It's in Trabuco Canyon in the Cleveland National Forest, about seven hours from the Bay. The catch is the access: the trailhead sits about two and a half miles up a rough dirt road that really wants high clearance, and forest roads here close after storms, so check current conditions first. Go after rain for the falls, and bring more water than you expect to need.
