Found this place on the map while searching for a place to camp at the Washington/Oregon border. This lovely little state park is near the mouth of the Deshutes River into the Columbia and it’s a great location for somebody heading south from Washington into Oregon and beyond on 97.  Staying here will avoid most of the I 84 and allow you to stay in a pristine natural area right on the river. The only disruption might be for some the noise of trains that ran across the river. The state park has several campsite loops, we stayed in the primitive tent site T Loop were there no hook ups and only a picnic table and fire pit. They also have electrical hooked up sites on loop A. A dump station is also available. Bathrooms with flushing toilets in loop A, otherwise many very clean pit toilets all throughout the park. There are 2 hiking trails and an old railroad bed bike trail departing from the state park and continuing south along the River. Many primitive campsites further up with only hike-in or bike-in or boat access. We saw two cyclist with overnight bikepacking gear staying here. We had reservations but did not need them on a midweek day in March but I suspect this place gets quite busy on weekends and in the warmer season. Good AT&T cell reception.
