Well worth the extra drive to get to the back side of the mountain, this campground is just down the road from the Sunrise visitor center with a few trails right through the campsite. On one end, Loop A offers more secluded sites with tiny waterfalls and streams running through it. At the other, Loop D is more flat and open but overlooks the nearby river. Plenty of options to suit all tastes. There is running water but no electricity in the bathrooms like the other major campgrounds at Rainier.
