Idaho Springs, CO: St. Marys Glacier

This Front Range dayhike is short on mileage and big on payoffs. In less than a mile, you’ll skirt a mountain lake and climb the snowy slopes of a Rocky Mountain glacier.

Trip Tools

Located just north of the ghost town Alice, this popular, 1.5-mile out-and-back in Colorado’s Front Range follows dirt roads and rocky trails up to the snowy slopes of St. Marys Glacier. Start at the pay parking area next to Fall River Road and walk southwest to reach the trailhead. The first 0.3 mile climbs up undeveloped roads before turning onto a rocky trail that leads to the banks of St. Marys Lake.
Half a mile in, cross a small bridge over the lake’s outlet creek and continue north, passing up-close views of Fox Mountain to the east (look for yellow-bellied marmots in the surrounding rocks and meadow). After 0.7 mile, the trail reaches the base of St. Marys Glacier. Climb another 100 yards up the glacier and take in views across the Silver Creek drainage. Follow the same route back to the trailhead.
Note: Stay on the trail. Most of the surrounding land is private property.
