The Narrows Zion National Park, Utah
There is no trail. The trail is the river. The Virgin River carves through Zion Canyon's narrowest section — walls rising 1,000 to 1,500 feet on either side, sometimes only 22 feet apart — and you walk upstream through the water itself, hopping between gravel banks and wading through currents that vary from ankle-deep to waist-deep depending on the season and that day's flow rate. It is one of the most famous hikes on earth, and the experience of rounding each bend to find new geometry of water and stone is unlike anything else in the national park system.
Cost No permit required for the bottom-up day hike — covered by your Zion entrance fee ($35/vehicle). Top-down through-hikes from Chamberlain's Ranch require a wilderness permit: $6 per permit plus $10 per person for day hikes, $20 plus $7 per person per night for overnight trips. Only 40 top-down permits are issued per day.
Two Ways to Hike It
Bottom-Up (no permit): Start at Temple of Sinawava — shuttle stop #9, the last stop on the Zion Canyon Shuttle. Walk the paved 1-mile Riverside Walk, then wade into the river. You can go as far or as little as you want. To reach the famous Wall Street section with the most dramatic walls, plan on at least 6 miles round trip. Big Springs (10 miles round trip) is the turnaround for bottom-up hikers. Allow a full day.
Top-Down (permit required): Begins at Chamberlain's Ranch about 1.5 hours from Springdale and runs 16 miles through the entire canyon. Can be done as a strenuous single day or a much more enjoyable overnight. Requires a private shuttle to the trailhead and a permit obtained through recreation.gov.
Water Levels — Check Before You Go The river flow rate in cubic feet per second (CFS) determines your experience. At 0–60 CFS, expect ankle to knee-deep water. At 60–90 CFS, conditions get moderately challenging. Above 150 CFS, the Narrows closes entirely. The NPS posts flow rates and flash flood advisories at the Visitor Center every morning — check them before heading out, every single time, regardless of how clear the sky looks in Springdale. Flash floods can originate miles away and arrive with no warning.
Cyanobacteria Check current advisories at the Wilderness Desk. If bacteria levels reach "Danger," the Narrows closes. Do not submerge your head in the water and avoid filtering drinking water from the river.
Gear — This Matters More Than People Expect Renting gear from a Springdale outfitter is strongly recommended, not optional in colder months. Options in Springdale include Zion Outfitters, Zion Adventures, and Zion Guru. Summer (May–September) footwear package with river shoes, neoprene socks, and a walking pole runs around $32–33 per person. Spring and fall dry bib packages (essential when water is cold) run $59–65. Full dry suits for cold water are $79–85. A walking stick dramatically improves stability on slippery, uneven river rocks — it is the single most useful piece of gear on this hike.
Getting to the Trailhead Take the free Zion Canyon Shuttle to stop #9 (Temple of Sinawava). No private vehicles allowed on the Scenic Drive during shuttle season (March–November). Catch the shuttle early — aim to be on the river by 8–9 AM.
Best Times Late spring and early fall offer the best combination of manageable water levels, bearable temperatures, and reduced crowds. Summer is popular and the water warms considerably, but monsoon season (July–September) brings increased flash flood risk — start early and watch the sky. Winter brings cold water requiring full dry suits; the experience is stunning and largely crowd-free for those prepared for it.
