Once the Arizona Department of Transportation closes Highway 67 south of Jacob Lake to vehicle traffic for the winter season, (usually by December 1) the North Rim of Grand Canyon National Park also closes to vehicle traffic.
The gate at Jacob Lake is closed and locked and the gate at the North Rim entrance station is closed and locked. The National Park Service does not unlock the entrance station gate for public vehicle access until North Rim visitor facilities open up for the season in mid-May.
