Take the dirt road, marked as plum canyon. You need some ground clearance
A loop along two forks of the plum canyon.
As the road forks, take the left one and park.
Hike further into the canyon and continue as the road ends.
Stay in the main canyon and at the first major fork keep left.
A dry fall is the only obstacle that can be easily past on the left side.
Go all the way to the end of the canyon. A bit before the end move to the right bank. As most canyons tend to be rocky, more narrow and filled with scrubs closer to the end.
Just over the top the next canyon is dead ahead.
It's a bit on the steep side, but granite and sand make it a lot easier.
Close to the end of the canyon a dry fall that's hard to cross, go back and go over the north bank.
Eventually you meet the California riding and hiking trail, go north.
Follow the California trail over the saddle and back toward the car. This is the easy part of the hike.
How to get there:
Take the dirt road, marked as plum canyon.
The road is not too bad and most cars with some clearance, should be able to make it to the trail head.
