The Cold Sore Snowmobile Trail #739 begins at an intersection with the Bonham Snowmobile Trail #544 approximately 3 miles from the Bonham Snowmobile Trailhead, it ends at an intersection with the Sunlight to Powderhorn Trail (SP) near the Mesa Top Snowmobile Trailhead. On the Sunlight to Powderhorn Trail Map the Cold Sore Trail is #13. This trail follows Forest Service Road 257 into the Cottonwood Lakes area, this section of the trail is groomed. It then climbs as it switchbacks through timber and crosses a boulder field to the rim of the Grand Mesa near Cold Sour Reservoir.  This section of the trail is marked, but not groomed and requires riding skills. The trail continues west until it reaches the SP Trail. The switchbacks can be challenging when snow conditions are poor.
