How to Get a Mount Rainier Wilderness Permit

The Wonderland Trail is about 93 miles long, it encircles Mount Rainier completely, and it gains roughly 27,000 feet on the way around. That is the trip most people want out of this permit, and it is why the permit behaves the way it does: one obvious, world-class objective, and a camp system that was never built to hand it out on demand.

The Park Service is unusually direct about this. On its own permit page, it states that it is unlikely you will be able to build a full Wonderland Trail itinerary during or after the general on-sale. That is the agency telling you, in writing, that the front door does not work for the trip most people want.

Which means the whole game here is understanding the other doors.

Mount Rainier permit, in one breath

• Covers: all overnight stays in the Mount Rainier backcountry. A permit is required year-round. Travel above 10,000 feet or on glaciers additionally needs a climbing permit and its own cost-recovery fee.
• Where: Recreation.gov, permit #4675317 (NPS wilderness permits).
• What you reserve: designated camps and zones, night by night, chained into an itinerary. Up to 13 consecutive nights / 14 days.
• The split: about two thirds of summer permits are reservable in advance. The other one third is issued first-come at wilderness information centers and never appears online.
• Group size: 5 people and 3 tents at standard trailside camps. Parties of 6 to 12 must use designated group camps, or camp on snow in Alpine Zones while climbing.
• Cost: $6 non-refundable per lottery application or reservation, plus $12 per person, per night. Youth 15 and under are free. Park entrance fee is separate.
• Three doors: a February early-access lottery, a general on-sale April 25, 2026 at 7 a.m. PT, and the permanent walk-up third.
• Cutoff: reservations must be made at least 2 days before your start date.
• Reservable window: trips from the end of May (May 1 for climbing camps and zones) through the first federal holiday in October. For 2026 the last reservable day is October 12.

How the system actually works

Door 1: the early-access lottery (February). Applications ran February 10, 2026 (opening 7 a.m. PT) through March 3, 2026 (closing 7 p.m. PT). Award status went out from March 14, and early-access reservations opened March 21.

Read what a win actually is, because it is easy to misread. You are not awarded a permit or a trip. You are awarded a place in the queue: a specific date and time when your personal booking window opens. The park’s stated reason for running it this way is that it stops thousands of people from competing for multi-night itineraries simultaneously, which is what shreds itineraries into unbookable fragments.

So the prize is position. An early access window means the Wonderland is still largely intact when your turn comes. A late window means you are picking through what earlier winners left, and the park says outright that later applicants may not get their preferred itinerary and should be ready to build an alternate trip. Lottery participants get one reservation during the early-access period.

Door 2: the general on-sale (April 25). Everything unreserved goes live to everyone at 7 a.m. PT on April 25, 2026, and that is also when lottery participants can start making additional reservations. This is a genuine door for a two or three night trip out of a single trailhead. For a full circuit, see the Park Service’s own assessment above.

Door 3, always open: the walk-up third. Roughly one third of camps are never reservable online at all. They are issued first-come at wilderness information centers, and can be requested a maximum of one day before your trip start. This is not a consolation prize. It is a third of the mountain, permanently, and it is the reason a sold-out screen on Recreation.gov is not the same thing as a full park.

Why a Wonderland itinerary opens one night at a time

Your permit is a chain of camps, one per night, and the chain has to be continuous. A ten-night circuit is ten separate camp reservations that all have to land on consecutive dates in a geographically sensible order. Which produces the defining property of this permit:

• One unavailable night in the middle blocks the entire trip, while every other night sits open and bookable.
• And the trip becomes bookable again the instant that one night frees up. Nothing else has to change.

Now add how camps come back. Cancel four or more full days before your reservation date and you are refunded, minus the $6. That refund is why cancellations actually happen here rather than quietly turning into no-shows. Itineraries can also be changed up to the day before if space exists, and every change that moves someone out of a camp puts that camp back.

There is a real limit worth stating plainly, because most guides get it wrong: no-shows do not come back to Recreation.gov. If a permit holder has not appeared by 12:00 p.m. on day one, the park cancels the reservation and those camps go into the first-come walk-up pool at the ranger station, not back online. The online signal is cancellations and itinerary changes. The walk-up line is where the no-shows land.

So “is my Wonderland trip bookable?” is not a question with a durable answer. It is a moving combination across dozens of camps and dates that re-rolls every time one person anywhere cancels one night. Checking that by hand, on a grid of camps against a grid of dates, is exactly the tedious job people abandon after ten days.

That is the problem BigDirtyHikes was built for: we watch your camps and your start dates and tell you when your trip becomes bookable, including when it is the one missing night that opened. You book it yourself on Recreation.gov. We make sure you see it in time.

Didn’t get your itinerary? Here’s the play

1. Cancellations, all season. The four-day refund rule keeps a steady return flow of camp-nights right through the reservable window. On a long circuit you are not waiting for a whole trip to reappear. You are waiting for one night, and one night is a far more common event.

2. The walk-up third, and go early. A third of camps are only obtainable in person. Wilderness information centers can issue them starting one day before your trip. Flexible hikers get on the mountain this way constantly.

3. Re-route around the blocked night. Because the constraint is per-camp, shifting one night to a neighboring camp, or reversing your direction of travel around the mountain, is often bookable when your original chain is not. On a circuit this is the highest-leverage habit there is.

4. Change the start date, not the trip. The whole chain shifts with it. Midweek starts clear far more often than Friday and Saturday.

5. Shorten the ambition, keep the mountain. A four-night section with a car shuttle is bookable in situations where a ten-night circuit is not, and it is the same trail.

The mistakes that keep people out

• Treating a lottery win as a permit. It is a place in a queue. Have your itinerary and two alternates built before your access window opens, because people with earlier windows have already taken camps.
• Only applying to the lottery. It is one of three doors. The April 25 on-sale and the permanent walk-up third both matter, and the walk-up third never runs out for the season.
• Waiting for no-shows to reappear online. They do not. Those camps go to the walk-up line at the ranger station.
• Missing the 2-day cutoff. Online reservations stop two days before your start date. Inside that, it is walk-up or nothing.
• Booking a reservation and thinking you are done. The permit is not effective until it is activated in person at a ranger station, where staff check photo ID, an emergency contact, and vehicle details. You can collect it one day before departure and no sooner.
• Missing noon on day one. Show up by 12:00 p.m. or call ahead. Otherwise the park cancels the reservation and your camps go to the walk-up pool.
• Budgeting a group at the wrong size. Standard trailside camps cap at 5 people and 3 tents. A party of six is not a large group in ordinary language, but it is here, and it needs designated group camps.

A note on conditions

As of August 2026, the SR165 Carbon River Fairfax Bridge is closed, and with it there is no access to Carbon River and Mowich Lake, for vehicles or pedestrians, with no alternate route. Mowich Lake is a standard Wonderland access point, so a circuit plan built around it needs rethinking before you book anything. Check the NPS conditions page for the current status.

You’ve got the permit. Now build the pack.

Rainier means glacier-fed river crossings, weather that ignores the forecast, snow on passes well into the summer, and on a circuit, a food carry measured in double digits. That’s what the BigDirtyHikes pack builder is for: build your Mount Rainier pack, watch the weight climb as you add gear, and reuse a gear closet trip to trip. Ten nights of food is heavy enough without carrying a redundant stove system too.

• NPS: the Wonderland Trail. Route logistics, food caches, and trailhead options, which is what a circuit itinerary is actually built from.
• NPS: current conditions. Road, bridge, and snow status. An early-season permit is worth nothing if the approach is closed.

Frequently asked questions

When is the Mount Rainier early-access lottery? Applications for the 2026 season ran February 10 through March 3, opening at 7 a.m. PT and closing at 7 p.m. PT. Award status went out from March 14, and early-access reservations opened March 21. The lottery opens in February each year, and the exact dates are re-announced on Recreation.gov each winter.

What does winning the Mount Rainier lottery actually get you? A place in the queue, not a permit. Winners receive a specific date and time when their personal booking window opens, and they can make one reservation during the early-access period. Earlier windows have the most complete Wonderland Trail options left; later windows may need an alternate trip.

How much does a Mount Rainier wilderness permit cost? A $6 non-refundable charge per lottery application or reservation, plus a $12 per person, per night recreation fee. Youth 15 and under are free, and if you win the lottery you don’t pay a second reservation fee. The park entrance fee and, for glacier or above-10,000-foot travel, the climbing cost-recovery fee are separate.

Can I get a Mount Rainier permit without the lottery? Yes, two ways. Everything unreserved goes on general sale April 25, 2026 at 7 a.m. PT, and roughly one third of camps are never sold online at all. They are issued first-come at wilderness information centers and can be requested up to one day before your trip start.

Are Mount Rainier permits refundable? Yes, if you cancel four or more full days before your reservation date. The $6 reservation charge is not refundable. That refund window is why camp-nights return to Recreation.gov steadily through the season.

Do Mount Rainier no-show permits go back on Recreation.gov? No. If a permit holder has not arrived by 12:00 p.m. on the first day, the park cancels the reservation and those camps join the first-come walk-up pool at the ranger station. Only cancellations and itinerary changes return camps to Recreation.gov.

Can I still get a Wonderland Trail permit if I lost the lottery? It is hard but not closed. The Park Service says plainly that a full circuit is unlikely to be buildable during or after the general on-sale, so the realistic routes are cancellations picked up one night at a time, the walk-up third, or a shorter section of the trail rather than the whole loop.
