Beautiful campground!  I only give it 4 stars because you are packed in like sardines, which most likely needs to be the case since it's such a small area under the Tetons.  Very good access to water all around the campground to put out fires or fill up your water tanks.  You can even take a shower here with a little cash.  Beautiful walk to the lake and I woke up to a moose about 30 feet from my campsite!!
