We stayed at Big Rock Campground, which is nicely wooded. We saw moose each day we camped there, so I'd recommend that CG for wildlife viewing. It's a 10 min walk to the lake, so if you'd rather be closer to the water look at Moraine or Roaring Fork CG. Only gripe is that people speed along the road that connects them all, so find a site on one of the loops.
Running water available in all loops.
