Deer Lodge sits in a wide valley between the Flint Creek and Highland mountain ranges, a small Montana town with a disproportionately interesting past. It is the county seat of Powell County and home to around 3,000 people.
The main draw is the Old Montana State Prison, right at the south end of Main Street. The original prison operated from 1871 to 1979, and the old cellblock is now a museum complex that includes an automobile museum, a frontier Montana museum, and a theatre. It is genuinely fascinating — the crumbling cell tiers and guard towers make for an atmospheric visit. At the north end of town, Grant-Kohrs Ranch National Historic Site preserves a complete 19th-century cattle operation run by the National Park Service.
Deer Lodge was also once a division headquarters for the Milwaukee Road railroad before its abandonment in 1980, and railroad history still marks the town. Main Street is now a historic district of well-preserved late-Victorian commercial buildings. The surrounding valley offers good fishing on the Clark Fork River and access to the mountains for hiking and hunting.
