How to Get a Glacier National Park Backcountry Permit
Glacier is the one where the scenery does not let up. Hanging valleys, turquoise lakes under 3,000-foot walls, goats on the ledges above the Highline, a night at a backcountry site with nothing between you and the Continental Divide. It is, unsurprisingly, one of the hardest wilderness camping permits in the country to plan around.
It’s also one of the most misunderstood, because Glacier’s front door is open for exactly one day a year. Miss March 15 and a lot of people conclude they’re locked out until next season. They’re not. There are three more ways in, and Glacier’s refund rules make one of them unusually productive.
Glacier backcountry permit, in one breath
- Covers: overnight wilderness camping in Glacier National Park. Required year-round; peak season is June 15 – September 30.
- Where: Recreation.gov, permit #4675321 (NPS backcountry reservations).
- What you reserve: per-night campsites, chained into an itinerary: night 1 here, night 2 there.
- The split: roughly 70% of campsites are reservable in advance. The other ~30% is held for first-come walk-ups.
- Cost: $7 per person, per night, plus a $10 non-refundable permit reservation fee. The lottery itself costs $10 per application, also non-refundable.
- Group limits: a standard permit covers 1–8 people (the track almost everyone is on) with a maximum of 4 people per single campsite. Parties of 9–12 aren’t shut out, but they run on a separate large-group track with far less inventory (see below).
- Two hard rules Recreation.gov enforces: a 16-mile maximum per day between camps, and 14 days maximum in the backcountry per permit and per calendar year.
How the system actually works
Door 1: the lottery, and it’s a one-day window. For standard groups of 1–8 campers, applications are accepted on March 15, 2026 only, 12:00 a.m. to 11:59 p.m. Mountain Time. One day. A $10 non-refundable application fee applies. Winners are notified March 17, and then book during a window that opens March 21 and closes April 30, 2026. About 3,000 standard advance reservations are available through this process.
If your group is 9–12 people, you’re on a different and much narrower track: applications are taken on March 1, 2026, notification is March 3, and the park issues only five large-group advance reservations per year. Five. Plan on splitting into two permits of 8-and-under instead.
Door 2: the general on-sale. Everything not taken through the lottery goes live to everybody on May 1, 2026 at 8:00 a.m. Mountain, and stays bookable through September 30, 2026. This is a substantial release, not scraps, and it’s the door most people should be circling on a calendar.
Door 3: the permanent 30%. Around 30% of all wilderness campsites parkwide are never sold online. They’re held for walk-up permits, obtained in person at a wilderness permit office. If you’re flexible about which sites you sleep at, this route exists every single day of the season regardless of what Recreation.gov shows.
The refund rule is why cancellations actually happen here
Most permit systems in the West are non-refundable, which means people who lose interest simply no-show and the space never comes back cleanly. Glacier is different: cancel more than seven days before your trip start and you get a full refund of the camping fees. (The administrative fee stays non-refundable.)
That single policy detail is the most useful thing on this page. When cancelling is free, people cancel. Plans change, partners drop out, weather forecasts turn ugly, and the sites go back into Recreation.gov. On top of that, itineraries can be modified up to two days prior, so groups constantly shed and swap individual nights right up to the wire.
The result is a steady, unglamorous drip of campsites returning to the system throughout the summer, at completely unpredictable moments, with no announcement, claimed by whoever happens to be refreshing.
And because your trip is a chain of camp-nights, one returned night is sometimes the only thing standing between you and a bookable itinerary. Watching for that by hand (a grid of campsites against a grid of dates, re-checked daily for weeks) is exactly the job people abandon after the first week. That’s what BigDirtyHikes is for: we watch your route’s campsites and start dates and alert you when something opens, including the single night that’s blocking your itinerary. You book it on Recreation.gov; we make sure you see it in time.

Didn’t get your itinerary? Here’s the play
1. Wait for cancellations: they’re real here. The seven-day full-refund rule keeps inventory moving all season. This is Glacier’s biggest advantage over parks with non-refundable fees.
2. Be at the May 1 on-sale. 8:00 a.m. Mountain, everything unclaimed, open to everyone. This is the best single shot most people get.
3. Take the walk-up 30%. Show up at a wilderness permit office. Nearly a third of the park’s sites are only available this way, every day of the season.
4. Re-cut the itinerary. The 16-mile daily cap and the 4-person-per-site limit mean the “obvious” routes concentrate demand on the same handful of camps. A route built around less-famous sites, or walked in the opposite direction, books when the postcard version won’t.
5. Split a big group. With only five large-group reservations issued per year, a party of 9–12 has vastly better odds as two permits of 8 or fewer.
The mistakes that keep people out
- Missing March 15. It’s a single day. There’s no grace period and no second window. If you take one thing from this guide, make it a calendar reminder.
- Building a route Recreation.gov will refuse. Over 16 miles between camps and the system won’t let you book it, no matter how fit you are.
- Ignoring the 4-per-site cap. A group of 8 doesn’t fit in one campsite. You need two sites at each night’s stop, which roughly doubles the availability you have to find.
- Forgetting the 14-day-per-year limit. It’s not just per permit. Two big trips in one summer can bump into it.
- Blowing the pickup window. Permits are picked up in person by 4:30 p.m. the day before or on your start date. There’s no online substitute.
- Assuming winter works the same. November 1 – April 30 runs through a separate application process entirely.
You’ve got the permit. Now build the pack.
Glacier means bear country protocol, weather that turns over fast at elevation, and long days between camps under the 16-mile cap. That’s what the BigDirtyHikes pack builder is for: build your Glacier pack, watch the weight climb as you add gear, and reuse a gear closet trip to trip. On a route with this much vertical, the ounces are the difference between a good day and a long one.

- NPS: backcountry camping. Campsite list, itinerary rules, and the walk-up permit offices that hold roughly 30% of inventory.
- NPS: current conditions. Going-to-the-Sun Road status, snow, and trail closures. Glacier’s season turns on this more than most parks.

Frequently asked questions
When is the Glacier backcountry lottery? For standard groups of 1–8, applications are accepted on March 15, 2026 only, from 12:00 a.m. to 11:59 p.m. Mountain Time. Winners are notified March 17 and book between March 21 and April 30, 2026. Groups of 9–12 apply on a separate date, March 1, with notification March 3.
How much does a Glacier wilderness camping permit cost? $7 per person, per night for camping, plus a $10 non-refundable permit reservation fee. Entering the lottery costs an additional $10 non-refundable application fee.
Can I get a Glacier backcountry permit without the lottery? Yes. Everything unclaimed goes on general sale May 1, 2026 at 8:00 a.m. Mountain and stays bookable through September 30. Separately, about 30% of all wilderness campsites parkwide are never sold online. They’re held for first-come walk-up permits at wilderness permit offices.
Are Glacier backcountry permits refundable? Yes, if you cancel more than seven days before your trip start date you receive a full refund of camping fees; the administrative fee is non-refundable. That refund rule is why cancelled campsites return to Recreation.gov steadily all season.
How far apart can my Glacier campsites be? Recreation.gov enforces a maximum of 16 miles per day between camps on advance reservations. You also can’t exceed 14 days in the backcountry per permit, or per calendar year.
How many people can be on one Glacier permit? A standard permit covers 1–8 people, with a maximum of 4 people per individual campsite, so a group of 8 needs two sites each night. Parties of 9–12 are not excluded, but they run on a separate large-group track whose lottery issues only five advance reservations per year, which is why splitting into two permits of 8 or fewer is usually the better play.
