I don't believe we've been there. But I love NW in general - such a beautiful place with lots of wild country.
The White River campground is at the North part of of the national park.
Ipsut Creek is at the North Western side.
Ipsut has I think 30 sites, White River has a little over 100 sites.
I liked the rustic setting of Ipsut Creek, but there was not much to see unless you hiked the trail up to the glacier.
At the White River campground, you have great views of the river and the mountain.
Here was the last time I was there, in 2010.

You can also drive a five mile or so road up to around 5,500', and then hike all around on trails.
That is called the Sunrise area, where the old pic of me and my boys is in the URL above.
Anyways, I have been to the White River campground numerous times, it is worth visiting many times.
