McCullough Gulch trailhead also uses summer parking limits
McCullough Gulch, a waterfall-and-alpine-lake hike on the north side of Quandary Peak, falls under the same summer parking reservations and shuttle system as Quandary.

McCullough Gulch is a shorter hike than Quandary’s summit, but it shares the same neighborhood and the same crowds. The trail follows an old mining road up the north side of Quandary Peak to White Falls and a high alpine lake, with big views of the drainage.
Because it sits in the same busy corridor south of Breckenridge, it falls under the same summer parking rules. During the summer reservation season, you park in the reserved Quandary Peak lot or ride the shuttle, and the shuttle system has included a leg that carries hikers on to the McCullough Gulch trailhead. Without that shuttle leg, reaching the trailhead means a walk up McCullough Gulch Road from the parking area; the distance depends on which lot you start from, so check the official pages for the current figure. Summit County does not allow roadside parking on McCullough Gulch Road, Blue Lakes Road, or Highway 9 here.
Why this matters: people sometimes think the parking rules apply only to the fourteener and try to squeeze in at McCullough Gulch. They do not, and tickets and tows follow. Planning the same way you would for Quandary saves the trip.
Before hiking McCullough Gulch, check the White River National Forest and Summit County’s Quandary parking and shuttle pages for current season dates, reservations, shuttle details, and the walking distance to the trailhead.
