How to Get a Last-Minute, National Park Backcountry Permit

By Michael Lanza

You really want to backpack in Yosemite, Glacier, Grand Teton, Rocky Mountain, Mount Rainier, Grand Canyon, or another hugely popular national park this year—but you didn’t apply to reserve a wilderness permit months ago? Well, you just may be in luck: Most parks have a system for getting a last-minute permit. It requires jumping through some hoops, understanding the system’s ins and outs, good timing, patience, and a bit of luck, but many backpackers get permits without a reservation every year.

This article shares the tricks I’ve learned from numerous backpacking trips to major national parks over more than three decades, including the 10 years I spent as Northwest Editor of Backpacker magazine and even longer running this blog. These tricks have helped me get a last-minute, walk-in backcountry permit even in very popular national parks like Yosemite, Grand Teton, Glacier, Zion, Grand Canyon, and others.

Follow these tips and you just might go backpacking this year in a classic national park.

Most parks offer walk-in, or first-come backcountry or wilderness permits, which is simply a permit that you obtain, without a reservation, based on availability, often no more than a day in advance of starting a multi-day hike—but sometimes a bit further in advance, such as in Yosemite, which issues walk-in permits three to seven days in advance.

The number of walk-in permits varies between parks, and availability is affected by advance permit reservations. But in general, parks set aside anywhere from 30 percent (in Glacier) or one-third (in Mount Rainier) to 40 percent (in Yosemite), half (in Zion), and even two-thirds (in Grand Teton) of available permits or campsites to be issued, in most cases, no more than a day in advance.

For starters, go to any park’s website and find out its procedure for obtaining a walk-in permit—especially where and when to do so. Demand for permits typically varies between different areas in the most popular parks—meaning that you may find permits available but perhaps not for the trip you had in mind; so it helps to familiarize yourself with different areas of the park’s backcountry and arrive there with options in mind.

Beyond that first step, four strategies are key to snagging a walk-in backcountry permit. Share your thoughts or questions about my tips—or offer your own tips—in the comments section at the bottom of this story. I try to respond to all comments. Click any photo to read about that trip.

Don’t like the uncertainty of trying for a walk-in permit? I’ve helped many readers of my blog secure a backcountry permit reservation in the midst of the prime season, even after they had tried and failed. See my Custom Trip Planning page to learn how I can help you do that.

#1 Go When Most People Don’t

Early or mid-July through Labor Day is the peak hiking season in most mountain ranges. Naturally, summer is when competition for walk-in permits is stiffest.

After Labor Day, though, the number of people seeking backcountry permits drops off dramatically in many parks, especially in the higher mountains of the West—partly because the summer vacation season has ended for many people, and partly because snow can fall in September.

But I’ve backpacked (and dayhiked) many times in September and even October in Western parks, including Yosemite, Glacier, Grand Teton, North Cascades, Mount Rainier, Olympic, and Yellowstone, in glorious, late-summer weather, with sunny, mild days and nights in the 30s to 40s Fahrenheit—although you should prepare for lows below freezing—and seen surprisingly few people on the trails, considering how pleasant it often is out there then.

I’ve long been in the habit of planning a roughly weeklong backpacking trip in the mountains for every September—it’s my favorite month because the weather is often good, bugs are generally gone, and permits are easier to get.

Backpacking in September or October certainly makes it even more imperative that you prepare for any weather, and accept the chance that a severe storm could force you to cancel your plans—or to simply go somewhere else. Still, in my experience, even when planning far enough in advance to book flights to a distant park—and thus, too early to know what to expect for weather—my September trips have had great weather most of the time.

#2 Go Where Most People Don’t

In many popular national parks, a few trails, trailheads, and areas attract the vast bulk of demand by backpackers. Examples include Yosemite’s core between Yosemite Valley and Tuolumne Meadows (including Half Dome and the northernmost section of the John Muir Trail); the Teton Crest Trail and Cascade and Paintbrush canyons in Grand Teton; the Highline Trail in Glacier; the Narrows in Zion; the Wonderland Trail at Mount Rainier; the High Sierra Trail in Sequoia; the High Divide-Seven Lakes Loop in Olympic; and the Grand Canyon’s South Kaibab, North Kaibab, and Bright Angel trails.

But in those same parks, vast areas—sometimes more remote and difficult to reach, but sometimes simply not as well known—receive far less demand, making it easier to secure a permit for them (whether walk-in or advance). With a park that provides current availability of backcountry campsites online, you can see which areas are the most popular, and avoid them, or at least have alternate hiking itineraries ready if you don’t get a popular hike (see tip no. 3).

Along those lines, there are national parks, like North Cascades and Capitol Reef, many parks in the Midwest, and nearly every park in Alaska, where backpacker demand remains so low that walk-in permits are easy to obtain. These parks have scenery just as beautiful as the flagship parks at the top of your list. If you don’t have flexibility in your vacation dates and don’t want to risk having to wait more than a day for a walk-in permit, go to one of these parks for an adventure just as memorable as any other.

#3 Keep Your Group Small

None of us wants to leave out our favorite backpacking partners, but the hard truth is that the larger your group, the harder it will be to get a permit, whether a walk-in a day in advance or a permit reservation months in advance. This simple statistical reality is based on availability—there are a limited number of backcountry campsites available for walk-in permits, and some of those sites may only have space for two or four people. Plus, many parks define backpacking parties larger than six or seven people as “groups” that require a larger campsite, and so-called group sites are far less numerous than standard backcountry campsites.

Keep your party to four or less, and you will significantly improve your chances of getting a last-minute backcountry permit—possibly even for a popular route like the trip I consider the best first backpacking trip in Yosemite.

#4 Get in Line Early

A walk-in permit is exactly what it sounds like: You show up, get in line, and see what’s available when you reach the front of the line. At any popular park, that line starts forming at least a few hours before the backcountry center opens. Get up really early and be first in line. Dress warmly and bring a book, a hot drink, food, a folding chair, and a headlamp, and make sure you know in advance where to go so you don’t wander around in the dark.

However, Yosemite National Park more recently launched what I think is a very good model for managing last-minute permits, issuing 40 percent of all daily trailhead quotas for walk-in, or first-come wilderness permits seven days in advance of the date you want to start hiking. See “How to Get a Last-Minute Yosemite Wilderness Permit Now.”

#5 Have a Few Trip Options Ready

Come prepared with multiple hiking-itinerary options—you may not get your first choice. That can be as simple as reversing your route or having alternative campsite options for some nights, but should include, if possible, alternative routes. Ask a backcountry ranger’s advice on where to go—that person may point you to a great hike that you hadn’t considered and which is available for your dates.

Be prepared to start hiking either that day or the next day; or, if nothing’s available, to return early the next morning to get in line again for a permit starting the following day (although you can usually start your trip by the next day, except in parks with the highest demand for popular hikes, like Grand Canyon and Zion).

One Final Tip

Next year, plan months in advance. Mark your calendar now to remind yourself. See my “10 Tips For Getting a Hard-to-Get National Park Backcountry Permit” for my top insights, based on many trips in major parks over the past three decades. Apply as soon as a park starts accepting applications, and submit them in two or three parks.

With luck, you’ll get at least one permit, and if you get more than one, well, that’s the kind of problem a lot of people would like to have.

  1. Hi Michael, I scored a permit for my (22-year-old) daughter and me for the Grand Canyon Nov. 6-9. Plan is South Kaibab to Bright Angel campground for 2 nights, then Bright Angel to Havasupai campground for 1 night, back to south rim. My wife is worried that it’s too late in the season and that it will be too cold. What kind of advice can you give me for prep that will help assure her?

    • Hi Dave,

      Congrats on your Grand Canyon permit, that’s exciting! Honestly, I would say the ideal autumn window is between the first week of October and roughly mid-November. It’s generally not too hot (especially later in that window) and not too cold/snowy/wet (especially earlier in that window). November will often be chilly and windy at the South Rim with an average high around 50 F and low around 25 F, but typically see comfortable temps down in the canyon, with days averaging 70 F and nights in the upper 40s F. Given that excessive heat is usually the weather to avoid, that temperature range really is manageable.

      Weather can certainly be quite variable in fall: On the second weekend of October 2018, my wife and I and another couple arrived at the South Rim (driving) on a day when there were thunderstorms, strong, cold wind, and rain at the rims. Over the next two days, we had glorious weather hiking rim-to-rim (S to N on Saturday, N to S on Sunday). We woke up Monday morning to cold wind and fresh snow at the South Rim on the day we left the park.

      You’ll need warm layers and a good wind/rain shell for starting out at the rim but may be in a T-shirt and shorts down in the canyon. And days are short, compressing your hiking time, so plan for getting up and moving in the morning. Be prepared for anything and you’ll be fine and have a wonderful adventure together. Enjoy!

  2. Great advice, Michael. I got aced out of the Early Access and just now the harsh reality of General Access for the Wonderland Trail (WT). I’m considering a Walk-up. I am wondering if the Rainier walk-up stations all open at the same time, or does any one of them open earlier than the others?? Besides the opening time, do you recommend any one of the walk-up stations over the others? I’m looking at a party of two, starting in mid-september. We can flex on the starting point trailhead, if that makes any difference in seeking a walk-up permit.

    I did the WT way back in 2002 (9 days clockwise from Longmire) and it wasn’t nearly this frustrating!

    Thank you.

    • Hi Bruce,

      Sorry you didn’t get an Early Access time slot, that’s a very competitive lottery. It sounds like you also failed to get a permit when general reservations opened yesterday; that would be a very difficult way to get a full Wonderland permit, given how many nights’ camps you have to string together.

      The four Wilderness Information Centers have the same hours. I’m sure they’ll have long lines and availability of backcountry camps will be managed in real time, so the only question is whether the line will be longer at some than at others. I don’t know this for a fact, but I would assume the busiest will be Longmire because that’s the main visitor area and easiest to reach, and that the smallest number of people would go to Carbon River, because that’s the hardest one to reach (and only open Sunday to Wednesday in summer). I could only guess whether White River or Paradise would have a longer line.

      Whichever you choose, I would plan to be at one of them at least a few hours before it opens, to get a spot at or near the front of the line, and be ready with multiple itineraries and starting trailheads. It’ll still be hard to get all the camps needed for a full Wonderland circuit on a walk-in permit. At least, you might get a permit for a great hike on a section of it.

      Good luck!

  3. This was really helpful! I didn’t realize (until 1.5 months ahead of my trip) that “in advance” was a whole 4 months–at least for the Grand Canyon. Do you recommend applying through the permit application anyways, even if it’s less than 4 months? Do people ever get lucky this way…?

    • Hi Stacie,

      Good question, but I can’t offer an encouraging response. Most Grand Canyon permits available for reservation get claimed very quickly after the first date you can apply. If you’re interested in backpacking corridor trails like the South and North Kaibab and Bright Angel, even if applying for that permit early enough, your chances of succeeding are about one in four or five; applying late, I’d put your chances at about one in 100, and almost zero for more than two people. Other trails have less demand but still significant demand in the peak months of April-May and late September into November.

      I have helped people get last-minute Grand Canyon permits through my custom trip planning, but at this point, it may not be for your desired itinerary or even successful, depending on your dates. You should also see my Grand Canyon e-guides if you’re considering a fall or later trip and applying four months in advance.
