The Westminster Hills Outer Loop offers a refreshing escape into wide-open spaces, perfect for a relaxed hike with your furry friend. This easy 3.1-mile (5.0 km) loop, with just 152 feet (46 metres) of elevation gain, takes about 1 hour and 18 minutes to complete, making it ideal for a quick outdoor fix. You'll traverse rolling prairie and grassy singletrack, enjoying expansive panoramic views of the Front Range peaks, including Longs Peak, and passing by the serene Mower Reservoir.
Planning your visit is straightforward, as there are no permits or fees required to access the Westminster Hills Open Space. The trail is famously dog-friendly, with the first mile from the trailhead designated as an off-leash area, so your canine companion can roam freely. It's a great year-round destination, but spring brings vibrant wildflowers, while winter offers stark, beautiful views across the open landscape.
This trail stands out in the Jefferson County area for its accessibility and diverse scenery, appealing to beginners and families alike. Beyond hiking, it's a popular spot for trail running and mountain biking, offering a multi-use recreational experience. The combination of easy terrain, stunning mountain backdrops, and a dedicated off-leash dog area makes it a local favorite.
