During the usual March–November Zion Canyon shuttle season, ride from the Visitor Center to Temple of Sinawava, Stop 9; most canyon access is shuttle-only then. Exact service dates change by year. The walk begins past the stop, where water and restrooms are available. Crowds are the main tradeoff, especially near the Narrows entrance, where the shared path narrows and people gather before turning back. Dogs aren’t allowed. The route is generally available year-round, but icy sections can close in winter, so check conditions before setting out. For a photo, put the river in the foreground and let the narrowing sandstone walls show how the canyon closes around it.
