Spent Fri-Sun (Aug 28-30) in site #55 on campground #1 loop.  We were on the west side of the loop and the last site directly on the water.  It is a back-in site and was wooded with a nice view.  We loved this spot, so much quieter than the rest of the loop.  This lake is all about boating so most of the sites are already packed in, then throw in most sites have a camper plus a boat on them and it can seem crowded.  From our site we could get in the water and use our SUP boards and swim around.  This spot is right between the bath house and dumpsters - about 2 min walk.  We would definately go back here and stay in the same area we were in.  There is a little beach and dock closer to the visitor center that was a 3/4 mile hike/walk each way (but we just swam at out site).

Would recommend Site #54, pull-through that will have you facing the lake and quiet.
