One of our favorite weekenders is a trip to Bannack, Montana, an historic ghost town that also served as a Territorial Capital during the 1800s. Above is the Livery Stable with tourist (me). Below is an interior view.
Bannack Days is a local celebration that features gold panning, parade, shootouts, pony rides, etc. , and a good time for all. The hyperlink takes you to the Bannack State Park website. There is a campground within a short walking distance too.
Here is a link to the official Montana Visitor information site: VisitMT.com. And this links directly to the Bannack State Park page.
Bannack with an "a" is the name of the town. Bannock, with an "o" refers to the indian tribe, which is part of the Shoshone, and now pretty much reside at the Fort Hall Reservation in Southeast Idaho.
