Red Mountain Creek Trail begins from a parking area at the end of Red Mountain Road, Forest Service Road 742.8H. This is also the northern terminus of the Timberline Trail, 414. Red Mountain Creek Trail follows Timberline Trail and Red Mountain Creek for two miles to the Collegiate Peaks Wilderness boundary. This is where Timberline Trail forks from Red Mountain Trail, with the latter leading to the left.
Red Mountain Trail continues to parallel Red Mountain Creek for two more miles. In the last mile the trail begins to gain elevation. It leaves the creek at approximately 10,880 feet and begins climbing steeply. During the next mile and a half the trail gains approximately 1,560 feet to reach the Continental Divide at Lake Pass. The northern side of the pass lies within the South Fork Lake Creek drainage. The trail becomes South Fork Lake Creek Trail, 1466, on the northern side of Lake Pass.
Directions from Highway 82: Take the South Fork Lake Creek Road, 391, (four-wheel drive only) to South Fork Lake Creek Trail, 1466. Hike four miles to Lake Pass on the Continental Divide. On the southern side of the pass the trail becomes Red Mountain Creek Trail.
Directions from Taylor River Road: Turn right on to Red Mountain Road, Forest Service Road 742.8H, and drive two and a half miles to the parking area for Red Mountain Trail.
