I was totally surprised by how wonderful it was to camp at Massacre Rocks State Park. Campground is divided into two loops (upper & lower). The upper loop sites oftentimes have more of a 'view' but were not very shaded and were also nosier due to the interstate in the distance. The lower loop is closer to the river and generally offers a little more shade and is a little quieter, but there aren't many "views" and the sites seemed to be smaller. Sites are gravel and fairly level (for the most part). Firewood is available for sale in the Visitor's Center (which also has a cute museum inside). If you're looking for a campground where you can so swimming, this is NOT the campground for you - Currents in the Snake River are very dangerous and signs are posted in many places warning that swimming and cliff diving should NOT be attempted. Plenty of beautiful walks along the river though and you can even hike a little ways to see the original wagon train ruts from the Oregon Trail.
