The trail starts on North Cottonwood Creek Road about .1 miles past the ending of Segment #12. The elevation of the trailhead is 9,350' as it climbs from the North Cottonwood Creek drainage. The trail parallels Silver Creek for 1.75 miles before crossing it. It crosses the creek at 11,100' and within .5 miles of entering the Collegiate Wilderness. Within 1 mile of entering the wilderness the trail reaches 11,900' on Mt. Yale's eastern flank and begins to descend into Hughes Gulch. Following Avalanche Creek for almost 2 miles the trail comes to Avalanche Trailhead and Cottonwood Pass Road (9,400'). This is a good place for mountain bikers to take up the trail as it leaves the Collegiate Peaks Wilderness before reaching the Avalanche Trailhead.
Continue walking south through the trailhead parking and cross Cottonwood Pass. The trail heads south east after crossing Cottonwood Creek. Stay on the southern side of Rainbow Lake. Approximately 2 miles past the lake the trail crosses County Road 344 and South Cottonwood Creek; and then it begins heading north. The trail crosses South Cottonwood Cutoff Road (343) then begins to lead south again and climb. Remaining lower than 10,000' the trail traverses the base of an unnamed 13,000' peak.
Four miles after crossing South Cottonwood Cutoff Road the trail crosses Maxwell Creek remaining at an elevation of 9,600'. Approximately 1.25 miles after Maxwell Creek the trail crosses a spur of Maxwell; and then it crosses Dry Creek in about .25 miles. Approximately 1.25 miles past Dry Creek the trail joins the Mt. Princeton Road. A signboard at this junction explains the next 5 miles of trail that follow roads to Chalk Creek. Mt. Princeton Road (322) begins as a rough, dirt road and ends at Road 321, which is paved. (From this junction it is only 1.5 miles to Mt. Princeton Hot Springs.) Follow County Road 321 to the right (south) to its junction with Chalk Creek Road. Walk west on Chalk Creek Road to Road 291. Continue walking 1 mile to a parking area and the Chalk Creek Trailhead.
