Stunningly beautiful!
This place is very well worth the 10 mile trek from I90. It's a NFS campground so fees apply, and bring correct change. The roaring creek and tall hill make the area private and the sites are also private. Gorgeous in every respect if you're in to nature. It's Montana, so bearproofing is necessary. 3 out of 10 sites were occupied mid-week in August.
