One of the many campgrounds along the Lower Crooked River, and is first come first serve.  I stayed in mid June and got the last campsite on a Friday night out of all the campgrounds so it fills up fast.  There is a trail that goes to the base of the dam for the Prineville Reservoir from the Campground.  There is also a large parking lot at one end of the campground that fills up with fishermen and car pools for people biking the highway.  Lots of the spots were large enough to fit Class A's in.
