This is definitely the smallest campground that I encountered while traveling through the South Hills of Idaho that are about a half hour away from Twin Falls.  There were only 2 sites that I could find while driving along this narrow stretch of the river, but they were definitely some of the best sites in the canyon!  Each of the 2 sites had metal fire rings and picnic tables and a vault toilet right at the split between the 2 campsites.  Another bonus was the seclusion you get from the other campground but unfortunately not the road, which isn't too big of a problem as the traffic is pretty light in the canyon during the week.  At the campsite further to the south there were 2 little rocks pools that people had made in the stream that were perfect for cooling off in after a long hot day of hiking around in the hills.  There were also dozens of trout swimming in and around these pools that would make it super easy to fish from a chair within site of your campfire!
