With its close proximity to Breckenridge, the 2.6-mile round-trip McCullough Gulch Trail is a popular trek that ascends past waterfalls and wildflowers to the picturesque Upper Blue Reservoir on the doorsteps of 14,265-foot Quandary Peak to the south and 13,950-foot Pacific Peak to the north.

The trailhead is located 2.4 miles west of Highway 9 at the end of unpaved McCullough Gulch Road, which is suitable for passenger vehicles during the summer and fall months. Arriving early helps to secure parking and avoid the peak-season crowds.

The hike begins at 11,100-feet on an old mining road and immediately ascends a steep grade through wildflowers and boulder fields. Watch for the surrounding mountains that occasionally peek through the pines. As hikers climb above tree line the forest gives way to open tundra and expansive views of the valley. At 1.3 miles lies Upper Blue Reservoir, where hikers can picnic, spot mountain goats, or play in the remaining snow during the summer months.

The short detour to White Falls Loop is a must-do, as it brings hikers right up to a set of steep waterfalls with various flora lining the banks of the falls. The loop returns back to the McCullough Gulch Trail, where hikers descend back down to the trailhead and parking area.

Trail is not extremely difficult, although getting up to the lake involves some heavily uphill elevation change. If you're lucky you might get to see some Mountain Goats.

The McCullough Gulch trail is popular and justifiably so. We were fortunate to spot several mountain goats grazing by the lake. The views in all directions were spectacular. But it was very crowded on a Friday.
