Antelope Trailhead and all trails will remain open; all access to CO 7 will be closed.

Boulder County, Colo. - The Hall Ranch main trailhead and parking lot will be closed starting tomorrow, June 2, through Thursday, June 9, due to heavy roadwork taking place as part of the Colorado Highway 7 CDOT project.

The Antelope Trailhead and all trails will remain open, but parking will be very limited and strictly enforced. The Picture Rock Trailhead at Heil Valley Ranch is nearby and recommended as an alternative during this closure.
