Warrior 1 and 2 is the claim it think, It is a fairly steep decent and climb back out.
You can park at Inaja park, which had picnic tables and grills.
I used to carry 1 bucket, 1 pan, a sluice box, shovel and a scoop.
Be cautious and you should make it up and down with out issue.
Be on the look out for Poison Oak there is quite a bit of it around.
Best of Luck
