“A relatively quiet trail, South Boulder Creek is an epic journey to the CDT.”— Tom Robson
The trail leaves the creek for a time then returns, climbs, and crosses the South Boulder Creek at several points before leveling off near Rogers Pass Lake. An obvious path leads beyond this lake to a saddle. From here, both Rogers Pass Lake and Heart Lake are visible. The South Boulder Creek Trail climbs steeply up several switchbacks to Rogers Pass. Adventurous runners can turn south for a climb up James Peak or north, along the Continental Divide Trail to Rollins Pass.
From Rollins Pass, runners can loop back to East Portal Trailhead by continuing easterly along the road and traversing the blocked Needles Eye Tunnel. Once over the tunnel and back onto the road, travel south to the upper Forest Lakes Trailhead. The Forest Lakes Trail connects back to the East Portal Trailhead.
