Lost Creek State Park is a 502-acre public recreation area in Deer Lodge County, Montana, about 6 miles north of Anaconda. Established in 1957, it preserves a narrow canyon where limestone cliffs and multicolored rock formations rise about 1,200 feet above the canyon floor. A short walking trail leads to Lost Creek Falls, a 50-foot waterfall that is one of the park’s main attractions. The park supports seasonal camping, fishing, picnicking, bicycling, hiking, and wildlife viewing, and visitors commonly see mountain goats and bighorn sheep there.
