Camp next to a ghost town!
Bannack is a ghost town that has been designated as a MT State Park. The 1860s mining town's buildings have been stabilized but not restored. It's fascinating. The adjacent campground would be handy but is $28 for those who are not Montana residents. The sites are closely spaced but do offer a few large cottonwoods for shade. A creek runs through the campground, and all was well maintained.
