ROCK CREEK RICHES

1. From Placerville in El Dorado County take Hwy 49 north .8 miles to the Hwy 193 junction; veer right onto Hwy 193.
2. Go 3.1 miles on Hwy 193 and turn right onto Rock Creek Road.
3. Go 5.5 miles on Rock Creek Road to a dirt turnout on the right where you'll park; this turnout is located about 100 feet past the Rock Creek bridge. To reach the northern edge of the claim, walk to the end of the short, downhill road that veers off to the right from the dirt turnout.

Google maps takes you directly there, same directions Jeff posted. I parked in the same turnout he mentioned about 100 feet past the bridge on the right side of the road. The claim starts right after the bridge so you can hike down past the power plant pretty easily (everything is graded nicely).

Just a quick overhead (aerial) view of the claim for those of you that are "visual learners" like myself, as well as marking out the recommended "Green Gate" access point mentioned by several others: The "Green Gate" access point is on the south side of the road, right after you cross the bridge and it comes up on you fairly fast on you.
***No vehicles allowed past the Green Gate - So it's all on foot from here on out!***

>>>FYI - The "GPAA access point" marked on the GPAA map of the area (marked in Red here) requires an extremely sharp & very hazardous descent of about 45 degrees down the hillside - If you are not a mountain goat, I wouldn't advise it! (Particularly as there is no cell service in the area, and getting injured is highly likely.)

Narrow paved road in and out. Easy for any vehicle. Parked along the shoulder near the cool old bridge and hiked down into the claim. Mostly panned and had some luck moving some decent sized rocks and digging under them. Saw a couple other folks out trying their luck, everyone was super nice. Watch out for the poison oak, my buddy got it pretty bad.
