Ascending Hikes – Green Mountain - Green Mountain Trail
This EXPLORATORY out-and-back hike to the summit of Green Mountain in William Frederick Hayden Park begins at the Green Mountain Trailhead, following the Green Mountain Trail as it climbs steadily through open grasslands and rocky, undulating terrain. The route gains approximately 850 feet of elevation over about 5 miles round trip, with moderate, sustained ascents, embedded stone steps, and exposed sections that can be windy and sun-baked before reaching the broad summit and its sweeping views. After taking in the panorama, the return follows the Hayden Trail, providing a varied descent across rolling foothills and reconnecting with the main route back to the trailhead.

This EXPLORATORY out-and-back hike to the summit of Green Mountain in William Frederick Hayden Park begins at the Green Mountain Trailhead and follows the Green Mountain Trail on a wide, well-maintained path across open grasslands. The route covers approximately 5 miles round trip with about 850 feet of elevation gain, climbing at a consistent, moderate grade on a surface that alternates between packed dirt, gravel, and embedded rock steps, with limited tree cover and sustained open views along most of the ascent. The summit area is broad and exposed, offering clear sightlines in multiple directions, and the return via the Hayden Trail provides a gradual descent on similar terrain before reconnecting with the main route to the trailhead.
