If you sleep anywhere below the rim, you need a Grand Canyon backcountry permit, and that is the hard part. Corridor campgrounds fill through a monthly lottery on Recreation.gov, and the popular spring and autumn dates go to people who applied five months earlier.
Read this before you plan anything: the route closes on 15 October 2026
A section of the North Kaibab Trail between Redwall Bridge and the north end of Cottonwood Campground closes to all public access from 11:59 p.m. on 15 October 2026 for Transcanyon Waterline rehabilitation. There is no detour around it.
Traditional rim to rim, in either direction, is not possible from 15 October 2026 until approximately February 2027. Cottonwood Campground stays open, but its water is shut off from 15 October, so anyone camping there must treat creek water.
If you were planning a late-autumn crossing, that window is gone. Plan for spring 2027, or switch to a rim-to-river-to-rim hike on the South Rim, which is unaffected.
Which permit, exactly
Only one permit matters for rim to rim: the Grand Canyon backcountry permit, issued by the park through Recreation.gov. It covers overnight camping below the rim, including the three corridor campgrounds you would use on this route.
| What you are doing | Permit needed |
|---|---|
| Rim to rim in one day, or one long night | None |
| Camping at Havasupai Gardens, Bright Angel or Cottonwood | Backcountry permit |
| Staying at Phantom Ranch | No backcountry permit, a separate Phantom Ranch lottery instead |
| Camping anywhere else below the rim | Backcountry permit |
Between 15 November and 28 February, corridor campground stays are treated as off-season and the permit requirement is relaxed. Check the current rule with the Backcountry Information Center before relying on it.
The lottery calendar, month by month
The system runs on a fixed monthly rhythm. Everything is keyed to the month your trip starts.
- The 16th, five months out. The lottery opens for trips starting five months later.
- The 1st at 5:00 p.m. MST, four months out. The lottery closes. One application per person per lottery.
- The 2nd. The park runs the lottery and reorders every applicant at random. The top 750 get an early-access slot.
- The 3rd. Applicants are told where they landed.
- From the 4th, 8:00 a.m. MST. Winners book, in groups of up to 15, across ten business days at 8am, 10am, 12pm, 2pm and 4pm MST.
- Around the 18th to 20th. Booking opens to every lottery applicant, winner or not.
- The 1st of the next month. Whatever is left opens to the general public.
Worked example: to hike in January, apply between 16 August and 1 September. Results land on 3 September. To hike in May, apply between 16 December and 1 January.
What it costs
- $10 per permit or lottery application, non-refundable.
- $15 per person per night below the rim.
- $4 per person per night above the rim.
- Nightly charges are refundable until 30 days before your start date.
- Win the lottery and book during your early-access slot and the $10 permit charge is waived.
A two-night corridor crossing for two people works out at roughly $70 in permit fees, plus the park entrance fee.
If you miss the lottery
Missing it is normal. There are three real fallbacks, in order of how well they work.
1. Book in the general-access window
Cancellations are constant. From the 1st of the month three months out, anyone can book what is left, and people drop corridor nights every week as their plans change. Check Recreation.gov daily rather than once.
2. Walk in at the Backcountry Information Center
Reservations can be made online up to five days before your start date. Inside that final four-day window, the only way to get a permit is in person at the Backcountry Information Center. Turn up early, be flexible about your dates, and be willing to take an unglamorous campground.
3. Do it in a day
The genuine answer for most people. A single-push rim to rim needs no permit at all. It is a long day, roughly 21 to 24 miles depending on which trails you link, and it demands real fitness and an early start, but the logistics collapse to almost nothing: park entrance fee, a shuttle booking, and a headtorch.
The catch: you still have to climb out
Skipping the permit does not make this easy. Rim to rim has no exit in the middle. Once you reach the Colorado River, the only way out is up, and the climb to Grand Canyon Village gains about 5,278 ft (AllTrails), almost all of it in the second half of the day when your legs are gone and the inner canyon can sit above 100°F. Every year, hikers who start too late or misjudge that climb get stranded below the rim after dark, and the Park Service warns outright against attempting rim to rim in a single day. Only go for it if your fitness, water, and daylight can cover the climb out.

No more than eleven people may camp in the same campground or use area. Affiliated groups are capped further: no more than four large groups or eight small groups camping in the backcountry at the same time. Large parties should split their dates rather than hope.
What the permit does not cover
- The park entrance fee. Separate, and payable whether or not you camp.
- Phantom Ranch. Beds and meals there run on their own lottery, opened far further ahead.
- The shuttle between rims. A private service, roughly four and a half hours by road, and it books out in peak season. Reserve it when you reserve everything else.
- North Rim access. The North Rim has its own seasonal opening dates, and services close long before the trail does.
How we would sequence it
- Pick your month first, then count back five months to find your lottery window.
- Set a reminder for the 16th of that month. The window is two weeks and there is no grace period.
- Apply with flexible dates. The lottery reorders applicants, not itineraries, so flexibility helps at the booking stage rather than the draw.
- Book the rim shuttle the day your permit is confirmed.
- If you get nothing, put the general-access date in your calendar and check daily. Failing that, plan the day hike.
Everything above is the park's own process as published by the National Park Service. Confirm dates, closures and fees on nps.gov and Recreation.gov before you apply. Trail closures in particular change with little notice.
Grand Canyon rim to rim permit FAQs
Not for a day hike. The National Park Service exempts day hikes from the backcountry permit requirement, and that exemption includes the pre-dawn starts most rim-to-rim hikers use. You need a permit only if you sleep below the rim. If you camp at Havasupai Gardens, Bright Angel or Cottonwood, you need a Grand Canyon backcountry permit from Recreation.gov.
Through the monthly early-access lottery on Recreation.gov. The lottery opens on the 16th of the month five months before your trip and closes at 5:00 p.m. MST on the 1st of the month four months before. The draw runs on the 2nd, results go out on the 3rd, and the top 750 applicants get a timed booking slot starting on the 4th. Anything unclaimed opens to the general public on the 1st of the following month.
Ten dollars per permit or lottery application, which is non-refundable, plus fifteen dollars per person per night below the rim and four dollars per person per night above it. The nightly charges are refundable until 30 days before your start date. If you win the lottery and book during your early-access slot, the ten dollar permit charge is waived. The park entrance fee is separate.
No. A section of the North Kaibab Trail between Redwall Bridge and the north end of Cottonwood Campground closes to all public access at 11:59 p.m. on 15 October 2026 for Transcanyon Waterline work, and stays closed until approximately February 2027. There is no detour. Rim to rim in either direction is not possible during that window. South Rim rim-to-river-to-rim hikes are unaffected.
Three options. Book in the general-access window that opens on the 1st of the month three months out, and check daily, because cancellations are constant. Or walk in: inside the final four days before a start date, permits can only be issued in person at the Backcountry Information Center. Or hike it in a single day, which needs no permit at all.
Reservations can be requested up to four months in advance, and the lottery that feeds those reservations opens five months ahead. The latest you can book online is five days before your start date. For the final four days, the Backcountry Information Center in person is the only route.
Eleven people is the maximum permitted to camp in the same campground or use area. Affiliated groups are limited further, to no more than four large groups or eight small groups camping in the backcountry at once. Larger parties are better off splitting across separate dates than applying together and hoping.
Moderate if flexible on dates.
