From the south end of Breckenridge, drive 2 miles south on Colorado 9. Turn right on Spruce Creek Road. Stay right up a small hill and turn left at an intersection. Stay on the main road and drive 1.2 miles (from Highway 9) to the Spruce Creek trailhead at 10,400’. There is a large parking area here.
To continue to either of the upper, 4WD trailheads, pass through the parking area and continue up the rough road:
Crystal Creek: After 0.2 mile, turn right and follow a narrow, rough road approx. 2 miles to reach Lower Crystal Lake, near 12,000’.
Spruce Creek: From the lower TH, drive nearly 2 miles on the easy 4WD road to reach the upper Spruce Creek trailhead, near 11,100’.
