I brought both my mtb and road bike. On my mtb I followed Badger Hill Rd which is a gravel road that gradually descends 500 ft over 2.5 miles through the forest then turned right onto a trail just prior to a bridge crossing a creek.  The trail follows the creek for awhile before it looped back to the campground. 34 mile round trip road bike ride passes many Apple Hill farms and uses a nice paved bike trail into Placerville. Routes to Jenkinson Lake also an option.
