This trailhead is accessed by five miles of rough, two-wheel-drive road. It is exceedingly popular, and parking is limited, especially on summer weekends. In winter, motorized access is typically not possible. Fourth of July Trailhead provides access to  Arapaho Pass, Diamond Lake, and  Arapaho Glacier Trails inside the Indian Peaks Wilderness.

At this trailhead is a small campground owned and operated by the City of Boulder called Buckingham Campground. Private property also exists in this area. Do not trespass.
