Zion Canyon is the most visited part of Zion National Park and offers easy, moderate, and strenuous hikes. Most Zion Canyon hikes are accessible only by the park shuttle from March through November and require stopping at the appropriate shuttle stop. Be sure to check the shuttle schedule prior to starting your trip and arrive early to find parking. All available parking fills quickly during the peak summer season. Trail closures may be in effect so check for current conditions. Trailhead Location: Up canyon from the Visitor Center and across the bridge adjacent to the South Campground. This trail can also be accessed from the Canyon Junction shuttle stop.
