Forest Lakes Trail

From the East Portal Trailhead, follow the South Boulder Creek Trail around the north side of the train tunnel. The trail soon enters James Peak Wilderness Area. It is 1.2 miles on the South Boulder Creek Trail to the signed Forest Lakes Trail junction. Turn right as indicated. The Forest Lakes Trail cuts across the front of a steep ridge on an old road for a half-mile until it intersects Arapaho Creek. It follows the creek for about another mile before it turns away from the creek to the northeast following a gentle grade to the lower of the two lakes. The trail leads around the lower lake and continues west to the upper Forest Lake, finally connecting to the Moffat Road another quarter-mile past upper Forest Lake.
