I am looking for a website to help me plan a camping trip to eastern WA. I want to go tubing down a river.? - camping wa

I was a few years ago with a large group, and driving a car a few miles, then back up to group together and flotation device like diving up to our car. I do not remember that the river was, but. Columbia could have been. I would love to do if someone could recommend a river, and how to find where in the river for departure and arrival.
