This is one of the most iconic and popular canyon hikes in Zion National Park.
At least 60% of the hike is spent wading, walking, and sometimes swimming in the river. Travel is rough and slippery in cold, fast flowing water, on top of slippery rocks. High water levels can prevent access sometimes. Use appropriate equipment and clothing to help protect you. Before your hike, always check the weather and flash flood potential. This hike is not recommended if there is a chance of rain in the forecast. Flash floods are deadly.
The Narrows is about the journey, not the destination. There is no one “viewpoint” or extra spectacular spot. The entire hike is beautiful, so hike for a few minutes, or a few hours, then turn around and return the way you came. Hiking from the Temple of Sinawava as far as Big Spring is allowed without a permit, which is 9.4 miles, round trip.

Visitors who plan to hike top-down, 16 miles, through the Virgin River Narrows will need a Wilderness Permit.
I would highly recommend the run and suggest bring hiking poles or I just grabbed a stick. Also a waterproof bag or "dry bag" would be helpful.
