See the Canyon by Shuttle

While there are plenty of Grand Canyon packages available, you really don't need a tour package to get around in the Grand Canyon. Most of the roads are open to private vehicles throughout the year, and most of the activities on the South Rim take place within a few miles of each other. The NPS also runs an extensive free shuttle bus system between Hermit's Rest in the west and Yaki Point/Kaibab Trailhead in the east. Shuttles run throughout Grand Canyon Village during the day and early evening, all year round. They also connect the Village with Mather Campground, the grocery store, bank, and post office at Market Plaza, and other points along the South Rim.
