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 unnamed lake 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.
