Take Salt Mine Road off the 260 out of Camp Verde.  After 8.8 miles, the road turns to well-graded dirt. Go left here and drive 2.4 miles to the Beasley Flat River Access Point.  There are changing rooms and picnic tables.  There is no camping at Beasley Flat, however there is a good riverside campsite on the way in, off to the left side of the road about a mile before getting to Beasley Flat.
