Welcome to Zion National Park, my name is Jonathan. Zion is a popular National Park where visitors come to immerse themselves within the grandeur of the canyon’s cliffs, and to challenge themselves with one of our many scenic and adventurous hikes. One of our more popular hikes visitors come to enjoy is the unique Narrows, a hike in a canyon that in places is only 20-30 feet wide, and 2000 feet deep.
However, unlike most hikes, taking on the Narrows means actually traveling upstream through the Virgin River on uneven, slippery, and rocky river boulders. Due to the risks of a hike like this, proper preparation is imperative, both for your safety and your enjoyment. Every hiker in The Narrows should have closed toed shoes, even just your regular hiking boots, and a walking stick. Although weather might be over 100 degrees the day of your hike, this narrow section of the canyon can stay considerably cooler, making non-cotton clothing, like polypropylene or wool, more ideal for its insulating benefits even while wet.
When you are planning your trip into The Narrows, you should also be aware of the flash flood potential. Afternoon thundershowers are possible throughout the year and a potential hazard to those hiking in slot canyons like The Narrows. During these events the river can quickly turn into a torrent of powerful rushing water, doubling and tripling in volume. Stop by the visitor center and speak with a ranger to get the most up to date conditions and the flash flood potential. Remember, even when you are prepared and conditions seem optimal, things can change quickly. Being aware of any changes in water clarity and increased river flow can go a long way in protecting your life. Being prepared and aware will help ensure a hike that will undoubtedly create positive memories that will last a lifetime. But please, ensure this opportunity for others by remembering to use the restroom before the start of your trip and to plan on packing out all your trash, including even the tiniest of crumbs. These simple guidelines will ensure the enjoyment of these special places for not only you, but generations to come.

Find out what to expect and how to prepare for one of Zion’s most popular hikes with Park Ranger Jonathan Fortner.
What is The Narrows?The Narrows is the narrowest section of Zion Canyon. This gorge, with walls a thousand feet tall and the river sometimes just twenty to thirty feet wide, is one of the most popular areas in Zion National Park. You can see The Narrows by hiking along the paved, wheelchair accessible Riverside Walk for one mile from the Temple of Sinawava. If you wish to see more, you will be walking in the Virgin River. This can involve wading upstream for just a few minutes or it can be an all day hike.
How can I hike The Narrows?A hike through The Narrows requires hiking in the Virgin River. You must get your feet wet since there is no trail. Most people choose to start their hike from the Temple of Sinawava via the Riverside Walk and then walk upstream before turning around and hiking back down to the Temple of Sinawava.
Hiking in The Narrows upstream as far as Big Spring does not require a permit. Doing the hike this way allows you to see some of the most spectacular and narrowest parts of the canyon. You can hike in the river for an hour and have a great experience, or you can hike as far as Big Spring, a strenuous, ten-mile round trip, all-day adventure.
You can also hike sixteen miles downstream over one or two days, entering the park soon after starting the hike and then exiting at the Temple of Sinawava. Those who choose this option must get a permit and arrange transportation for the one and a half hour ride to start the hike outside the park at Chamberlain's Ranch.
When should I hike The Narrows?Most people hike The Narrows in the late spring and summer when the water tends to be at its warmest and the water level drops. However, this is also the time of year that storms can cause life-threatening flash floods.
Winter and early spring commonly means cold water and high water levels. The Narrows can be closed during the spring when snowmelt raises the river over 150 CFS. Fall brings more stable weather, but days get shorter and the water temperature drops. Zion Weather and Climate
How high is the water?Water level fluctuates greatly from year to year and day to day depending on many factors such as rainfall and snowmelt. When the river is running below 70 cubic feet per second (CFS), walking is moderately difficult, with knee deep crossings on the slippery and uneven river bottom with frequent pools up to waist deep.
When the current goes above 70 CFS, walking against the current becomes challenging and crossings of mid-thigh deep are frequent with pools that can be chest deep. If the flow goes to over 150 CFS, The Narrows will be closed to all travel. The Narrows also closes when a Flash Flood Warning is issued by the National Weather Service, and remains closed for two hours after the warning is lifted. Current River Flow
What about flash floods?The Narrows are susceptible to flash flooding because much of the surrounding area is bare rock that does not absorb water. During storms, runoff is funneled rapidly into the Narrows. During a flash flood the water level rises almost instantly--within seconds or minutes. Flash floods are common in Zion and hikers have been stranded, injured, and even killed by venturing into narrow, flood prone canyons.
Harmful cyanotoxins have been found in the Virgin River system. Many remote areas in Zion’s wilderness cannot be regularly monitored for toxins, therefore current conditions may not be known. There is no known recreational water filtration or disinfection method that can reduce the toxins to a level that is safe for drinking water. Filter and disinfect all drinking water directly from springs to reduce the risk of toxin exposure.
What should I wear and bring?Close-toed shoes and a hiking stick are recommended for hiking on the slick, uneven rocks in The Narrows. High canyon walls and water create cooler conditions than anywhere else in Zion Canyon, so wear and bring seasonally appropriate synthetic layers. Equipment and Clothing Recommendations
What else should I know?There are many recommendations and park regulations that apply to your trip in The Narrows. Please follow these guidelines to help protect the park and keep yourself safe while visiting.
