Grass parking lot next to the noisy freeway. The campground is very clean, all grass. The restroom and showers are so, so. If you are a bike rider, the paved bike path is right next to your site. The river is also next to the park.
Very nice park. Green grass and trees make this a nice place to stay on the way to Yellowstone. Came here and took a visit to Rigby, the home of Philo Farnsworth, the inventor of television. Must see the museum they have with some of his inventions.
