Hidden Gems in Silverado Canyon

The Sinks

Viewpoint · Moderate · Hike in

Red sandstone cliffs of the Sespe Formation, "aged between 20-40 million years old," form an eroded amphitheatre that the Irvine Ranch Conservancy calls "Orange County's miniature Grand Canyon." The viewing platform sits nearly 4 miles one way from the Augustine Staging Area and is reached only "during scheduled programs and Wilderness Access Days"; registration is required, but all activities are free.

• Access: Scheduled programmes and Wilderness Access Days only. Registration required in advance, though the activities themselves are free.
• Effort: Nearly 4 miles each way from the Augustine Staging Area.
• Conditions: Exposed badlands terrain. No shade and no water.

Black Star Canyon

Trail · Moderate · Hike in

Named for the Black Star Coal Mining Company, founded in 1879, which drove some 900 feet of tunnel and pulled out "six to ten tons of medium- to low-grade coal" a day; it is also the site of an 1831 clash that recent scholarship describes as "a communal massacre." Sources disagree on access: Wikipedia says the lower canyon is OC Parks land "open for scheduled programs only," while LAist reports the road is surrounded by private property but "the public is allowed to travel it."

• Access: Open on scheduled access days only, first come first served.
• Parking: Limited trailhead parking that fills at opening.

Holy Jim Falls
