At the Temple of Sinawava, the last shuttle stop in Zion Canyon, visitors can follow the one-mile Riverside Walk beside the North Fork of the Virgin River toward the entrance to The Narrows. This mostly paved trail usually takes one to two hours round trip, although travelers should check current conditions for flooding, ice, and closures and use the park shuttle when private vehicles are restricted (National Park Service [NPS], 2025a). The towering canyon walls consist mainly of Navajo Sandstone, which formed from ancient desert sand dunes. Over millions of years, the Virgin River carved through these rocks, while erosion of the softer Kayenta Formation beneath the sandstone caused pieces of the cliffs to collapse and gradually widen the canyon (NPS, 2024).
The river creates a cool, green habitat that contrasts with Zion’s surrounding desert and supports Fremont cottonwoods, box elders, hanging gardens, birds, amphibians, and four native fish species (NPS, 2025b). Recent restoration work has focused on improving this river ecosystem: in 2025, Zion National Park removed a small dam near the Temple of Sinawava that had blocked fish movement for 68 years. Scientists are now monitoring the river to learn how native species, including the flannelmouth sucker, respond to the newly reopened upstream habitat (NPS, 2025c; Condos, 2025).
