There's a few places. Go to
Huntington and down to the river. Take a left and used to be a big area down there a few miles. or go to Richland and find thr road down to the river. Several miles down there but big pull out right at the bottom I camped in several time's. Got a name but I can't remember it. Come to think of it, go in at Huntington and if you don't find something the river road follows the river up to where you'd turn off for Richland
