Bannack is the site of Montana's first big gold strike, on July 28, 1862. By 1863, more than 3,000 people lived in walking distance of the 50 buildings lining Bannack's Main Street. The log and frame structures, now a National Historic Landmark, are still there, the state's best-preserved ghost town.
The annual Bannack Days festival, featuring reenactments and history-themed activities, is held the third weekend of each July. A visitor center is open from Memorial Day through Labor Day.
Grasshopper Creek runs through Bannack, and a campground on its banks features a tipi available for rent, fire rings, horseshoe pits, volleyball, firewood, and tent and RV camping.
