Commercial images could also be restricted from May through September, as a result of conflicts with customer use and congestion. All vehicles have to be parked in designated areas only; no off-road site visitors. The Tioga Road and the Glacier Point Road are closed throughout winter and often re-open in June. The Mariposa Grove Road is intermittently closed in winter due to icy conditions. See the Superintendent’s Compendium for added closures, use limits, and/or restricted activities.
