Cache La Poudre Trail - 18.4 Miles Round-Trip

The Cache La Poudre Trail begins at the Poudre Lake Trailhead on the west side of Rocky Mountain National Park. It follows the Cache La Poudre River 9.2 miles down a wide open valley to the Mummy Pass Trail junction, 1.3 miles from the Corral Creek Trailhead in the Comanche Peak Wilderness.

This lightly used trail offers excellent wildlife viewing, solitude and big open spaces. Mild terrain and modest elevation gains make the Cache La Poudre Trail achievable in a day, but consider camping overnight to fully explore and enjoy this immense river-valley corridor:

The trail begins north of Poudre Lake on the west side of the valley, and immediately drops to the west side of the headwater. It runs close to the forest edge, but mostly through open space on a gentle, rolling grade.

The first 4.5 miles are an unmaintained cross-country route between the river and forest. Despite that classification, the trail is fairly well-defined and intuitively followed. Hikers should have little trouble keeping track of their location given the distinct path it takes down valley and by the river.

The same path is used extensively by elk, which readily take this path of least-resistance. The trail loses clarity through 4.5 miles (10,338') as you pass a forested knoll on the west side of the valley - edge back down toward the river, and the trail will soon reappear.

You'll reach spurs for the Cache Campsite and Chapin Creek Campsite along a good section of trail (approx 5.25 miles and 5.5 miles from the trailhead). Note these signs may be in disrepair and difficult to see - if camping, anticipate these signs and use a map for guidance.

Here you'll notice the main valley narrowing, and branching into smaller valleys that run W-NW. The trail now runs through intervals of dense montane forest before emerging in a long, open area adjacent to the river (7.2 miles : 9,985').

It re-enters the forest on a high bank (8.25 miles), then drops to a willow-marsh along an oxbow (8.8 miles : 9,965'). Travel levels to the Mummy Pass Trail split at a major bridge (9.2 miles : 9,753').

The Mummy Pass Trail turns east over the bridge to the Hague Creek Campsite, located just above the confluence of Hague Creek and the Cache La Poudre. It continues 2.6 miles east to the Mirror Lake Trail junction. You may also hike another .5 miles from the Mummy Pass Trail split to the Park Boundary and Corral Creek Trailhead in the Comanche Peak Wilderness.

Worth Noting

  • Flatiron Mountain (12,335') is the most prominent peak on the skyline, visible much of the way.

  • The first 4.5 miles of trail pass through a Cross Country Travel Zone, meaning that significant portions are unmaintained and unmarked. Despite this classification by the NPS, the trail is relatively easy to follow.

  • Staying close to and following the river through unidentifiable segments will ensure that you stay on course and regain the trail when it becomes more visible.

  • The first few miles can be muddy year-round, obscuring the established route.

  • While there is only a small net elevation loss relative to the trail's total distance, there are frequent minor elevation changes along the way that, in aggregate, add to the hike's overall difficulty.

  • Look for elk, moose, deer, bear, mountain lion, fox and coyote along this trail. Elk and moose are particularly common.
