The Subway is the most photographed place in Zion that most people never see, and the reason is administrative rather than physical. There are more ways to fail to get a permit here than there are ways to get one.
Two completely different trips, one permit
Hikers and canyoneers going into the Left Fork apply the same way for the same Wilderness permit. The only difference is the trailheads on it.
Bottom-up, which is what most people want: a very strenuous 9-mile round trip from the Left Fork Trailhead on the Kolob Terrace Road (from Virgin, not Kolob Canyons at Exit 40), up the Left Fork of North Creek and back, with route-finding, wading in ankle- to knee-deep water and scrambling over large boulders. No ropes. Recreation.gov puts it at 6 to 10 hours for most groups.
Top-down, which is canyoneering: a very strenuous 9.5-mile through-hike from the Wildcat Canyon Trailhead to the Left Fork Trailhead that needs rappelling skills, 60 feet of rope, extensive route-finding, and swims through deep pools of very cold, debris-filled water. Two trailheads means a car shuttle, and arranging it is your job.
Nobody can take you
Paid guided trips are not permitted — the Park Service’s words — and Recreation.gov’s permit page says the same.
This is the part people find hardest to accept, because everything else in American outdoor recreation can be bought. It cannot here. The Left Fork is Wilderness, guided activities are prohibited in Zion Wilderness, and no amount of money produces a legal guided Subway trip. The full picture of that rule is here, including the part people get wrong — guiding is allowed on frontcountry trails, just not in here. If a guide is what you need, the guided canyons all run outside the park, and six outfitters’ guided canyoneering tours are compared here.
Other hard rules:
- Maximum group size 12 for the Left Fork. Das Boot and Russell Gulch are 6.
- Day use only. No overnight camping in the Left Fork.
The money
| Lottery application fee | $6, non-refundable in all circumstances |
| Per person fee | $10, refundable |
The refund rule: the per-person fee comes back if you cancel, or cut the group size, before 5 p.m. on the day of the trip.
Note that $10 is not the $3 per person people remember from Angels Landing. Different system, different fee, and the assumption that one carries over is a common and expensive surprise.
The seasonal lottery calendar
This is the table worth bookmarking. Applications open on the 1st and close on the 25th.
| Trips in | Apply | Unclaimed released |
|---|---|---|
| Jan / Feb / Mar | 1–25 November | 15 December |
| Apr / May / Jun | 1–25 February | 15 March |
| Jul / Aug / Sep | 1–25 May | 15 June |
| Oct / Nov / Dec | 1–25 August | 15 September |
All releases at 10 a.m. Mountain Time.
If you are reading this in late 2026: the window for January to March 2027 is 1 to 25 November 2026, until 3 p.m. Mountain Time on the 25th, and unclaimed permits for those months are released at 10 a.m. on 15 December 2026.
How it runs: you apply online during the window, up to four months ahead, with up to four date choices, and one application per person, per canyon, per season. Results arrive by email on the 27th of the month. If you win, you have two weeks to claim the reservation on Recreation.gov.
How the day’s spots split: Recreation.gov issues 75 percent of each day’s Left Fork spots through this seasonal lottery and 25 percent through the daily lottery two days ahead, and it does not separate top-down from bottom-up parties for the quota. The seasonal lottery is where most of the permits are.
Claim it or lose it. Two weeks, and an unclaimed reservation goes back into the pool on the 15th of the following month at 10 a.m. MT. That release is a real second chance and almost nobody watches for it.
The daily lottery, two days out
Two days before the trip date you can apply between midnight and 3 p.m. Mountain Time. The draw is at 3 p.m. and the results email arrives by 4 p.m. Anything not taken through either lottery becomes a walk-in permit the day before or the day of the trip.
So there are genuinely four ways in: seasonal lottery, the 15th-of-the-month release of unclaimed spots, the daily lottery two days out, and walk-ins. Most people try the first one, lose, and go home.
You still have to collect it in person
Every Wilderness permit is issued in person at the Zion Canyon Visitor Center Wilderness Desk. Allow at least 20 minutes, bring the make, model and plate of every vehicle, and send the person named on the reservation, because only they can collect it.
Three things in there that end trips: in person, 20 minutes, and the reservation holder must be the one who collects it. If the person whose name is on the permit is driving separately and meeting you at the trailhead, you do not have a permit.
The membership almost nobody knows about
Zion Express lets regular visitors turn online reservations into Wilderness permits from home. You join by watching three orientation films at the Zion Canyon Visitor Center Wilderness Desk. It is free, and membership lasts three years.
Free, three years, and it removes the in-person pickup entirely. If you come to Zion more than once, sit through the three films on your next visit — it is the single highest-value hour available at the Wilderness Desk.
Before you go
The Left Fork is a narrow canyon with water in it, and the flash flood rules matter more here than almost anywhere in the park. A forecast for storms twenty miles upstream is a forecast for this canyon.
And if the lottery does not go your way, the alternative is not another canyon inside the park, because the same guiding ban applies everywhere in the Wilderness. It is the country east of the boundary, which is what the trip below is: a guided UTV ride to slot canyons on land outside the park.
