From Breckenridge, drive 8 miles south on Colorado 9. Turn right (west) on the Blue Lakes 850 Road. Drive a few hundred yards and turn right on the McCullough Gulch 851 Road. Drive 2.1 miles to the end of the road near a gate. Before 2 miles, there is a road junction, stay left on the main road. Park on the side of the road.


Taken from 14er Quandary Peak, 1 shows the upper portions of this route. From the trailhead, pass a gate and follow the road up to the left. After 0.5 mile, leave the road on a signed trail - 2. Continue into the forest, over small log bridges and across a boulder field - 3. Near 11,600', stay right ( 4) and continue up a rocky hill and to an unnamed lake, at 12,000' - 5.

Walk around the right side of the lake and follow the trail up a rocky slope - 6. Continue to 12,400', just south of a rib which runs west-to-east in the basin below Fletcher Mountain and Atlantic Peak. Enter the upper basin and follow the faint trial west toward Atlantic Peak - 7. Just north of a small lake (12,555'), turn right and continue north - 8. Work your way across 1/2 mile of rough talus to reach the base of a slope/headwall, at the northwest end of the basin - 9 and 10. This headwall is the crux of the route.

Look for the easiest section in the center and ascend the loose terrain - 11. When snow-covered, an axe and crampons are recommended. Near the top, angle left and gain easier terrain at 13,200' - 12. Hike northwest to reach the ridge connecting Atlantic and Pacific Peaks - 13. Angle slightly right of the saddle and ascend to the ridge crest - 14. Hike north along the ridge, bypass a small point near 13,500' ( 15) and continue up Pacific's south ridge ( 16, 17 and 18) to reach the summit.

If you'd like to add Atlantic Peak on your ascent or descent, leave this route near 13,400' and hike south to reach Atlantic - 13. Gaining Atlantic and returning to this route adds about 0.75 mile. Refer to Atlantic Peak's Northeast Slope route for more information and photos of the upper route.
