It is a long drive from Twin Falls to get to this park, so you’d better hope there is space when you get here! It was full when we arrived, but we would definitely come back at a less busy time. Primitive camping right on the water (bugs could be a problem) and most of the camping was in tents (although it was posted that tents are not allowed Monday through Thursday), however, you could park your van/RV alongside the water. I only saw pit toilets and they were reasonably clean (others mention bathrooms which to me mean flush toilets but maybe I missed them). Note that THE Balanced Rock is about a mile down the road from the campground.
