Fifteenmile Trail #456 is an expert-level out-and-back hike in Oregon's Mt. Hood National Forest, within the Barlow Ranger District. The trail is about 10.9 miles long, and the round trip climbs to about 5,250 feet, with a total gain of roughly 3,350 feet. The route is front-loaded, with the steepest stretch at about 5.5 miles in, where the grade reaches 22 percent. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Government Camp show July and August highs around 70°F with only about four wet days a month, while winter brings highs in the mid-30s and rain on most days. That station sits about 1,270 feet lower than the trail's high point, so temperatures on the route run cooler. The trip takes about nine hours. Underhill Trail and Cedar Creek are both about 3 miles away, and Underhill campground is about 3.7 miles off. Climbers can find Campfire boulders about 5.3 miles away.
