We camped in the lower area and enjoyed it. Sites are close together though. Not much room to maneuver a trailer over about 25 feet.
Have camped here for years. The road in the campground is tight on some corners for longer rigs. A lot of spots are difficult to back into with a trailer. Small trailers and tents will work best up here. There are vaults and some flushers during the peak season. Lake gets very busy on weekends but is fun.
