Phoenix is four hours from the South Rim of the Grand Canyon; Las Vegas, five. There are 2,000 parking spots on the South Rim, and in summer there are up to 6,000 cars—ditch yours in a designated parking area and take the free Eco-Shuttle to the trailheads and into Grand Canyon Village.
Most North Rim visitors travel the five hours from Vegas. Most visitors to the Grand Canyon come to the South Rim, arriving on Arizona Highway 64. The Highway enters the park through the South Entrance, near Tusayan, Arizona, and heads eastward, leaving the Grand Canyon through the East Entrance. Some thirty miles of the South Rim are accessible by road.
A much smaller location for holiday makers is found on the North Rim, accessed by Arizona Highway 67. There is no shuttle along the North Rim (closed late autumn to mid-May), but parking is less scarce than at the South Rim.
