In order to get to the Riverside Walk one must board a propane bus at the visitor center. The Zion Canyon Scenic Drive is closed to all other traffic. The trail starts at the end of this road. Historically the trail was called Gateway to the Narrows, but now the popular name and the name the NPS advertises is Riverside Walk. This 2-mile round-trip stroll begins at the farthest end of Zion Canyon, in a natural amphitheater called the Temple of Sinawava. The well-traveled path, host to approximately 3,000 people a day in the summer, ends where Navajo Sandstone walls close in and water is forced into the narrow walls of the world renowned Zion Narrows.
