There is no trail. The river is the trail, and that one fact explains everything else about this hike.
How it works
Ride to the end of the line — stop 9, Temple of Sinawava — and walk the paved Riverside Walk for a mile. Where the pavement ends, you step into the water and keep going upstream until you decide to stop.
It is an out-and-back with nothing you have to reach, which is the best thing about it. An hour up and back is a real Narrows hike, and the walls start closing in well before most people turn around.
Going all the way to Big Spring is a full day. The Park Service’s bottom-up page puts it at 9.4 miles out and back — the figure in the fact box above — and its main Narrows page rounds that to a ten-mile round trip. Budget daylight on the ten.
Either way the distance is not the problem — walking on unseen cobbles in moving water is much slower and more tiring than walking on ground.
Orderville Canyon joins the Narrows about two miles up and is a common side trip. You may go a quarter mile up it and no further: past that, upstream travel is not allowed, and the upper canyon is a canyoneering route with a permit, entered from the top.
The three numbers that decide your day
The park publishes thresholds rather than opinions, which makes this one of the few hikes you can check rather than guess at.
- Under 70 CFS — moderately difficult. Knee-deep crossings, pools to the waist.
- 70 to 150 CFS — walking against the current gets hard. Thigh-deep crossings, pools to the chest.
- Over 150 CFS — closed to all travel. Spring snowmelt did this in eight of the fifteen springs from 2012 to 2026, which is why an April trip can arrive to find the headline hike unavailable. The Park Service’s record of those closures, year by year, is on the spring page.
And one rule that is not about flow at all. The Narrows closes automatically the moment the National Weather Service issues a Flash Flood Warning, and stays closed for at least two hours after the warning is lifted. That is the rule most likely to take out a day you have already paid for, and no flow reading tells you it is coming.
The park’s own guidance on floods is blunt: they are possible at any time, and they have happened on days they were not forecast. Rain twenty miles upstream under a blue sky above you is the exact scenario that kills people in slot canyons.
Check these the morning you go, not the week before
- River flow — USGS gauge 09405500, Virgin River at Springdale. This is the gauge the 70 and 150 CFS numbers refer to, and the one the Park Service points at.
- Flash flood potential — NWS Salt Lake City flash flood forecast, which is where a Warning would appear.
- Whether it is open right now — Zion current conditions.
If you read nothing else on this page before you leave the hotel, read those three. The park information line is 435-772-3256, and rangers answer it between 10 a.m. and 5 p.m. Mountain Time.
One more thing about the water you are standing in. Cyanobacteria producing the nerve toxin anatoxin-a have been found in the North Fork of the Virgin River, which is the river you walk up. The Park Service’s guidance is not to submerge your head in it and not to drink it — and it is explicit that no filter or purification tablet removes the toxin. Carry what you need. There are potable water points at the Visitor Center, the Human History Museum, Zion Lodge, the Grotto and Temple of Sinawava.
Gear, and why you will probably rent
The Park Service is specific — closed-toe shoes and a sturdy stick, and sandals, Crocs or bare feet are not appropriate. Quick-drying fabric matters more than it sounds, because the canyon is shaded and cold: hypothermia in ninety-degree weather is an ordinary Narrows outcome, not an exotic one.
Springdale outfitters rent the whole package, and in cold months dry bibs or a dry suit. Renting is what most people do and it is the right call unless you already own river shoes.
Reserve it ahead. The thing that runs out in high season is not the gear, it is your size in the gear, and a walk-in gets whatever is left. Zion Adventures recommends reserving dry bibs and dry suits from 1 October to the middle of May, and its footwear, dry-bib and dry-suit packages are linked at the end of this page. It fits boots and gives its orientation the evening before, though it does not promise the gear itself for pickup until the morning. Zion Outfitter, by the park entrance, holds a reserved size only until 10 a.m. The fall water temperatures, and everything else that changes after 25 October, are on the October and November page.
What it costs, per person per day, before tax: Zion Adventures’ packages as of 30 October 2026, Zion Outfitter’s as of 19 September.
| Package | Zion Adventures | Zion Outfitter |
|---|---|---|
| Boots, neoprene socks, stick | $35 | $35 |
| Dry bib on top of that | $65 | $59 |
| Full dry suit | $79, youth sizes $59 | — |
Zion Adventures adds sales tax and fees of about 14% at checkout. So the honest range is about $35 to $79, and which end you land on is the season, not your taste: footwear only in summer, a dry bib in late spring and early fall, and in winter, when the Park Service puts the water at 38 to 45°F, a dry suit or at least a dry bib. What each shop recommends for December to February, and their holiday hours, are on the winter page.
With a guide
The bottom-up Narrows is a frontcountry trail, so a guide with the park’s authorization may lead it, and two guided days from Springdale are below. Both operators are on the Park Service’s list of authorized frontcountry hiking guides.
From October to February, the private hike is the one with dates. Cedar & Sage Boutique Trekking takes your party alone along the Riverside Walk and about two miles up the river to Orderville Canyon, with the cold-water gear included — bib waders from October to May — and a picnic on the way back down the canyon. It has no date on sale from March through May 2027.
Good Trip Adventures’ full day has dates from 1 March 2027. It picks up from Springdale hotels, in a group of up to eight, and stops at Zion Outfitter on the way in, where you rent the gear yourself. If the river is closed that day, it becomes a tour of the rest of the park.
