Monumental is an easy out-and-back hike in Idaho's Boise National Forest, within the Cascade Ranger District. The trail is 3.6 miles long, with a one-way elevation gain of 561 feet, and it rises from about 6,666 feet to a high point of 7,384 feet. The Forest Service manages the land, and the trail is open year-round. The route is natural-surfaced and allows both horses and bikes, so it works for riders and pack animals as well as hikers. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Deadwood Lodge, which sits about 1,400 feet lower, show July highs around 82°F with lows near 40°F, while winter highs there stay in the low to mid 30s. Several other trails lie within a few miles, including Cup Corral Cutoff about 2 miles away and the Middle Fork Payette River at roughly 2.9 miles. For an overnight stay, Stolle Meadows Cabin is about 7.8 miles off, and Silver Creek Campground is about 9.6 miles away.
