We rolled into Green River at about 1 AM after 18 hours of driving from Washington. It had never felt so good to fall onto the ground and go to sleep. The only thing that was a problem throughout the night was the sound of a train going by (this likely couldn't be heard from all of the camp sites) and horses neighing from who knows where.

The grounds have clean bathrooms and accessible water. Each campsite has at least 1 picnic table as well and a fire pit (I believe). We didn't spend long at in Green River State Park, but it was a nice convenient place to stay the night after a LONG day of driving.
