Cube Iron Mountain is a 4.1-mile out-and-back hike in the Plains/Thompson Falls Ranger District of Lolo National Forest in western Montana. The trail rises from about 6,579 feet to about 6,911 feet, a climb of roughly 555 feet one way, and is managed by the Forest Service. The trail is natural-surfaced and open to both bikes and horses, making it a versatile route for riders and equestrians. The Forest Service's trail records confirm that both are allowed. Summer is the most comfortable time to go. At a nearby weather station, typical July and August highs average around 70°F with only about six wet days a month, while winter highs stay near freezing with frequent rain and snow. That station sits several hundred feet lower than the trail's high point, so expect temperatures on the summit to run cooler. The trail lies within about a mile and a half of the Four Lakes Creek trailhead and the South Fork Four Lakes Creek hike. For an overnight stay, Cougar Peak Lookout is about 4.7 miles away, and Clark Memorial Campground is about 7.9 miles off.
