From the small town of Ririe, ID just north of Highway 26 find Archer Road (4700 E) and follow it north to where it crosses the snake river.  Past the bridge a few hundred yards turn right (east) onto 10000 S. Road.  Follow that to the end and then turn right on Snake River Road.  Follow this road always staying near the river.  It turns into Heise Road and eventually Burns Creek Road.  Follow this almost to the very end where you will find a dirt parking area and boat ramp by the river.
