Corner Mountain Trail System is a 14-mile out-and-back hike in the Laramie Ranger District of the Medicine Bow-Routt National Forest in Wyoming. The route climbs from about 8,500 feet to about 8,800 feet, with a total elevation gain of 255 feet. The trail is a natural-surface route and is rated hard, so it is best suited for experienced hikers. Summer is the most comfortable time to go. Typical July averages from a nearby weather station run around 76°F for highs and 48°F for lows, though that station sits a few hundred feet below the trail, so temperatures up high run cooler. The trail is managed by the Forest Service and is open year-round. Parking is at the Corner Mountain trailhead, and the trail is not accessible. Willow Campground and Pine Campground sit about 0.2 miles away, and Aspen Campground is about 0.5 miles away, making the trail system an easy base for an overnight stay. The North Fork Little Laramie River, a canoeing spot, lies about 0.9 miles off.
