The Greenway and Westminster Hills Loop offers a refreshing escape into wide-open prairie, delivering sweeping views of the Colorado Front Range, including the iconic Longs Peak. This easy 3.0-mile (4.8 km) hike, with a gentle 159 feet (49 metres) of elevation gain, takes about 1 hour and 15 minutes to complete. You'll traverse varied terrain, from gravel paths to singletrack, winding through rolling grassy hills and past the serene Mower Reservoir, fringed with cottonwood trees.
Planning your visit is simple, as this accessible loop requires no special permits or fees. The trailhead is particularly popular with dog owners, as a large portion of the Westminster Hills Open Space functions as an off-leash dog park. For the best experience, consider visiting in spring when the area bursts with wildflowers, or during the cooler months for comfortable hiking conditions.
This trail is a fantastic example of the connectivity within the northern Denver metropolitan area, linking into the larger Rocky Mountain Greenway Trail system. Beyond the stunning mountain vistas, the natural areas around the loop and Mower Reservoir provide excellent opportunities for birdwatching and spotting local wildlife, making it a notable spot for nature enthusiasts.
