New Melones aka Glory Hole
Map, directions and a million photos and ride reports about it on my site. I was there Wednesday and the wildflowers were even more spectacular. It's about 4 miles south of Angels Camp on Hwy 49. Don't worry if it has been raining, or even if it is raining. It holds up very well. Start from lower parking lot, go out Frontier to the end, do Angels Creek clockwise, go do Buckbrush counterclockwise. Repeat these two loops a few times, go back via Frontier and go up and then down the switchbacks of the Tower Climb. Not a difficult trail system but very fast roller-coaster, and this time of the year very beautiful.
