There is a museum here - worth the visit.  There is camping on the bar downriver from the creek - three trails lead up the bank.  There are picnic tables and the only flush toilet on the Dam to Pittsburg landing stretch is just north of the ranch.  There is a hike up the creek to an old cabin if you want a hike.  This is also a good place to fish for sturgeon - easiest from the Oregon side of the river.
