From Breckenridge, drive 8 miles south on Colorado 9. On a sharp corner of Colorado 9, turn west onto the Blue Lakes Road, #850 road. It is 2.1 miles to the trailhead below the dam. Continue on Blue Lakes road as it climbs west. After 1.2 miles, keep right. After 1.4 miles, keep right again. By early June, the road is usually open to the dam. If not, drive as far as possible and hike the remainder of the road. There is a large parking area below the dam.
During Winter and early Spring, this road is usually not plowed far past the residential areas here.
