Tenmile is a hard hike in the Rexford Ranger District of Montana's Kootenai National Forest, about 9 miles long with an elevation gain of 1,190 feet. The trail is an out-and-back, starting at the Ten Mile TH 21-Upper parking area and climbing from a low point of about 2,600 feet to a high of about 4,600 feet. The route is open from June through October. That season is the most comfortable time to go, with typical averages from a nearby weather station at Fortine showing July highs around 84°F and lows near 50°F. That station sits about 1,600 feet lower than the trail's high point, so temperatures up top run cooler. The trail is natural-surface and allows both horses and bikes. It is not an accessible route. Nearby, the Blackfoot Divide (Pinkham) mountain biking area is about 2.6 miles away, and the Ural Creek and Ziegler Mountain hikes are within about 4 miles. Rocky Gorge Campground, about 6.3 miles off, offers a place to stay.
