This is my favorite place to stop while travelling through along I84. It is so convenient being right next to the freeway. Only negative is that it's right next to the freeway so it's a little noisy but doesn't bother me. Big day use area too for a nice picnic.
Quiet and clean. There are no hook ups but there are water spickets and restrooms
There is the Grande Ronde river right there, BBQ pits and plenty of space! Restrooms and fresh water are available.
Although this park is near the highway, it makes for a great day visit or overnight camping. The river is very close and the Umatilla National Forest is a just a short drive up the river.
Hilgard junction is a small 18 site campground just below highway 84 west of La Grande. It is right on the grande ronde river which was cool and peaceful when we were there. I am not sure many people know about this spot, I didn't and I have been driving by for 6 years now. Even if you are traveling through the day use area is a great place to stop and stretch your legs. Even though the freeway is about 60 yards away and up the hill the traffic noise was muted.
