Last summer we stayed a night in American Falls at a marina/campground. Not very close, but a was the best we could find. Under new owners so don't let old reviews throw you.
We did consider Minidoka Wildlife Refuge. No hookups but not too far off the path.
If you haven't seen it Craters of the Moon is a must! Nothing like it!!
