Fish Creek State Park covers more than 5,600 acres, making it the largest state park in western Montana. The forest reflects decades of logging and includes a historic fire tower atop Williams Peak. The 1910 Great Burn, the region's largest fire, burned three million acres in less than three days. The park offers fishing, hunting, camping, hiking, horseback riding, OHV use, and snowmobiling on open roads, along with a 70-mile network of logging roads. Crystal-clear emerald pools along Fish Creek are a highlight, and the park provides access to the Clark Fork River in Alberton Gorge, a whitewater rafting area. Wildlife is abundant, with 47 mammal, 113 bird, three amphibian, and four reptile species, including moose, elk, bears, mountain lions, and wolves. The creek is a stronghold for Montana's native trout, including bull trout and westslope cutthroat trout.
