Red Mountain Trail

Overview

This west-side route is a 6.4-mile total out-and-back with about 1,387 feet of gain, typically taking around 3–3.5 hours. It’s a moderate-to-difficult effort with a few steep, rocky pushes and a reputation for lighter crowds. The payoff: sweeping looks at the headwaters of the Colorado River and the Never Summer Range—without committing to a summit.

Route

Start at the Colorado River Trailhead in the Kawuneeche Valley. You’ll first drop into the broad headwaters valley, then begin the Red Mountain climb through the area known as Hell’s Hip Pocket. After intermittent steep sections and a small pond, the trail meets the historic Grand Ditch Road near the park boundary—your natural turnaround for this hike. Note that this route does not summit Red Mountain. A spur continues toward Thunder Pass between Lulu Mountain and Static Peak if you’re extending the day, but most day hikers return at Grand Ditch.

Why hike it (and why you might skip it)

If you’re choosing between this spur and the popular Lulu City path, this one trades some easy cruising for more elevation and bigger views—it’s underrated and usually less busy. The catch: the hike begins with a descent, so you’ll finish with a climb back to the trailhead, and a few stretches have loose gravel that require sure footing. It’s also not a dog hike—pets aren’t allowed on park trails. Horses are permitted.

Nature notes

Expect open valley vistas, summer wildflowers, and good chances to spot moose in the marshy headwaters. You’re looking across to the Never Summer Range, whose igneous history contrasts with the ancient granite and gneiss common elsewhere in the park. The broad U-shaped valley forms and moraines here are classic signs of past glaciation.

Best time to hike

May through October is the sweet spot. Snow and mud can linger into early summer on the west side, so start early for cooler temps, firmer tread, and quieter wildlife viewing. During peak season, the park uses a timed-entry system, and seasonal closures on the high road across the park can affect access—check status before you go.

Tips

• Wear sturdy footwear; trekking poles help on the steeper, loose sections.
• Give moose a wide berth—back away if you see one on or near the trail.
• For backpackers, the Valley View campsite is accessed from this corridor; plan ahead and reserve permits well in advance if you’re making it an overnight.

Logistics

Park at the Colorado River Trailhead on the park’s west side; toilets are typically available. No pets on trails. Expect lighter crowds than many east-side hikes, but start early for the best experience.
