Mill Flat Campground offers five primitive campsites along the Kings Wild and Scenic River at 1,100 feet elevation, making it ideal for whitewater rafting enthusiasts seeking Class III rapids.

The first-come, first-served campground is free and features vault toilets and picnic tables, but campers must bring their own water and obtain required campfire permits.

Note that the remote location is unsuitable for trailers due to rough access roads (47 miles east of Fresno on CA 180, then 17 miles on Trimmer Springs Road), and special food storage rules apply in this active black bear country.
