Mount Edwards & Grays Peak loop via Argentine Pass Trail

While the tour is categorized for jogging, the Mount Edwards & Grays Peak loop via Argentine Pass Trail is primarily suited for experienced hikers and trail runners comfortable with very challenging, high-altitude terrain. Many sections involve significant elevation gain, rocky paths, and even Class 2/easy Class 3 scrambling, making sustained jogging highly improbable. It's best approached as a strenuous hike.

The terrain varies significantly. You'll encounter old mining roads that can be bumpy and rutted, singletrack trails through bushes, and a slow, grinding ascent to Argentine Pass. Higher up, especially between Mount Edwards and Grays Peak, expect technical ridge walking with scrambling that requires using your hands. The final push to Grays Peak is a steep and exhausting climb.

The best time to hike this loop is typically from late June through September, once the snow has largely melted from the high elevations. Early season (June) may still have significant snow drifts, particularly at higher altitudes and on north-facing slopes. Fall offers stunning aspen colors but can bring colder temperatures and early snow.
