Trail Information

From the St. Vrain Mountain Trailhead, the St. Vrain Mountain Trail starts off on an old road, but soon leaves it to the right. It cuts over to the creek which it reaches about a mile from the trailhead, a third of a mile beyond the Indian Peaks Wilderness boundary. It follows along the creek for another half mile, then takes quite a long switchback to the right (north). It is easy to lose the trail here if there is snow.

The St. Vrain Mountain Trail cuts back to the left, crosses the valley and continues a ways across the south side of the valley before switching back and returning to the drainage. After a few more smaller switchbacks, the St. Vrain Mountain Trail comes out above treeline and passes to the south of Meadow Mountain. It pops briefly into Rocky Mountain National Park as it circles the west side of a small unnamed peak, then gains the east ridge of St. Vrain Mountain.

At 3.9 miles, the St. Vrain Mountain Trail intersects the unsigned Rock Creek Trail near the St. Vrain Mountain Trail’s highest point, a good place to break from the trail if you want to summit St. Vrain Mountain by an easy bushwhack up the ridge. This junction is marked by a cairn and is south of the head of the Rock Creek drainage. The trail continues down the south side of St. Vrain Mountain to the Buchanan Pass Trail.

When the snow falls, the St. Vrain Mountain Trail becomes the domain of snowshoers and backcountry skiers.


To reach St. Vrain Mt. Trailhead, take County Road 107 (Ski Road) southward out of Allenspark from CO 7 for about 1 and one-half miles. At this point, FDR 116.1 heads up the hill to the right for a half-mile to the St. Vrain Mt. Trailhead. Continuing west along FDR 116 another 3.3 miles, part of it four-wheel drive, leads to the Rock Creek Trailhead.
