First time on this trail about 2 weeks ago. I have a 4Runner with 4WD, but ended up parking in the shade where the county maintained dirt road ended as it was very clear where the maintenance ended; and I didn't want to risk getting stuck way out there. It was about 1/2 of a mile to get to the trailhead (located on right hand side of the road). Trailhead not clearly marked- just a metal gate with a hikers entrance. Other hikers have posted pictures. No water in the creek and plenty of poison oak and foxtails. Pants would be a good idea on this trail. Overall, beautiful views and very peaceful amongst our California Oaks. Pretty isolated, so bring plenty of water and come prepared.
I recently did an overnighter to the camp. Poison oak was unavoidable in some spots. There weren't many ticks, but I had a few on me when I got to camp and when I got home. Wear long pants and take plenty if water if you're camping. The creek had small holes, but it wasn't flowing very well.
This is an excellent creekside hike that leads into the Garcia Wilderness and visits a remote, seldom-used backcountry trail camp. You'll need a high-clearance vehicle to get to the trailhead, and finding the unsigned trailhead itself is somewhat challenging. If you can get past these challenges, the hike itself is a worthy reward. It's best to go in the spring when the weather is cool and the wildflowers are blooming.
