One of our favorite places to visit! Mt. Rainer is a must for anyone living in the PNW and this campground allows you to stay in the park but gives you access to plenty of trails, waterfalls and is just a short distance from entrance to the Wonderland Trial (93 mile train around mountain, also requires a permit to hike).  Although you do have to drive a bit to get to the other entrances, it is still worth the visit! The Ohanapechosh creek runs through the campground and campsites along it allow you to wander down and stick your feet in some glacier frigid water while exploring the driftwood piles accumulated over the years.
