Mt. Hillyer is a moderate out-and-back hike in the San Gabriel Mountains National Monument Ranger District of Angeles National Forest, managed by the Forest Service. The trail is about 3.6 miles long, with a one-way climb of 553 feet from a low point of about 5,625 feet to a high of about 6,197 feet. Spring and fall are the most comfortable times to go. Typical averages from a nearby weather station at Mt Wilson show May highs around 70°F and October highs around 72°F, while July and August average in the mid-80s. That station sits about 487 feet lower than the summit, so temperatures on top run a little cooler. The trail is on natural surface and allows both horses and bikes. Horse Flats campground is just 0.1 mile away, and Bandido Group Campground is about 0.4 mile off. Climbers will find Cluster 2 and Between Romeo Void and Main within about 0.2 mile.
