This is a small campground located just north of the hwy. along the Snake River. Several sites in lower loop have outstanding river views. Sites are mostly well spaced, gravel and level. Some pull through sites good for big RVs. Almost every site had water and elec. Several nature trails and geology trail. Restrooms looked standard but did not use. Small visitor center provides Oregon Trail history of the area and the rocks. About two miles away in a different park of the park is Register Rock showing names of OT settlers located in a nice picnic park. You can make reservations on line but we drove in about 2pm and had a choice of sites. Would have given 5 stars except for some uneven sites. We will definitely come back as we pass by or stay a few days just to enjoy sitting on a rock above the river.
