Really beautiful. Where in Washington? I lived in Washington for 15 years and never heard of them. I'm sorry I missed them!
They are almost exactly halfway between Mt. St. Helens and Mt. Adams in the Gifford Pinchot National Forest on Forest Service Road 90. Then a 500-600 foot walk from the parking lot through the campground to the falls. It's not a hike it's a stroll. Viewpoints have been constructed there.
