Oxbow
Road noise can be loud here. Try to get a site as close to the river as you can so you can avoid the highway noise at night. The bathrooms here are great - showers, running water, and flush toilets! The river is refreshing on warm days to swim in. We like this because it's an easy day trip from Portland. (Avoid camping next to the porta potties - we did that one time and a truck at 6:30am came to empty them. Granted it was a weekday but it was not the best way to wake up.) Next time we learned and got a site closer to the real bathrooms. Sites are pretty private though you will hear your neighbors!
