Green Mountain is a hard out-and-back hike of about 8.5 miles in Colorado's South Platte Ranger District, part of the Pike and San Isabel National Forests. The trail runs from a low of about 7,473 feet to a high of about 8,156 feet, with a one-way climb of roughly 400 feet. The Forest Service manages the land. Summer is the most comfortable time to go. Typical averages from a nearby weather station in Bailey, Colorado, show July highs around 79°F and lows near 44°F. June and September run milder, with highs in the mid-70s and low 70s. The route starts at the Buffalo (Colorado Trail) Trailhead, and it is open year round. The parking area also serves as the trailhead for the Colorado Trail (Segment 3) and the Tramway mountain biking route, both within about a tenth of a mile. Buffalo Campground sits about 0.9 miles away, and Little Scraggy Dome, a climbing area, is about 1.8 miles off.
