Yosemite Backpacking Permits: The Complete 2026 Guide

Staring at Recreation.gov while Yosemite wilderness permits vanish in the literal blink of an eye can make you wonder if sleeping in the backcountry is some kind of myth.

You refresh the page.

You click the date.

Everything is gone.

How can that be!?

The Yosemite permit system is fiercely competitive and can be very confusing. At times it feels like you need a PhD in spreadsheets and alarm clocks just to go for a hike.

But beneath the anxiety-inducing countdowns and rejected lottery emails, there is a system.

Once you understand that structure, the process becomes far less mysterious - and your chances of getting a permit improve dramatically.

This guide explains how Yosemite wilderness permits actually work, why they’re so competitive, and a few realities nobody tells you before you try to get one.

If the permit lottery feels like a headache, I handle all the wilderness permits for my Yosemite Backpacking Trips.

What is a Yosemite Wilderness Permit?

Before we dive into strategy, it helps to understand what you're actually trying to get.

A Yosemite wilderness permit is an overnight use permit. If you're sleeping anywhere in the backcountry - anywhere outside of a developed campground such as Yosemite Valley Backpackers Campground - you need one.

No exceptions.

Day hiking does not require a wilderness permit. But the moment your plan includes sleeping out there, you need a wilderness permit.

A permit is tied to two things:

• A specific trailhead

• A specific start date

What it does not guarantee is a specific campsite.

Instead, it guarantees your right to enter the wilderness from that trailhead on that day as part of a controlled quota.

And that quota is absolute.

Yosemite's backcountry is finite. The permit system is how the National Park Service manages human impact so meadows, creeks, and fragile alpine ecosystems don’t degrade.

Every trailhead has a daily cap. Once that number is reached, the trailhead “closes” for that date. It doesn’t literally close - it just means no more permitted backpackers can start from that trailhead that day.

It doesn’t matter how far you drove.

The number is the number.

Yosemite Dispersed Camping & Wilderness Rules

Can you camp anywhere in Yosemite?

Short answer: you can camp almost anywhere. Long answer: there are a few rules worth knowing first.

One - you must follow wilderness permit rules. 

• You must camp at least four trail miles from Tuolumne Meadows, Yosemite Valley, Glacier Point, Hetch Hetchy, and Wawona, and at least one air mile from any road.
• You must camp at least 100 feet (30 meters/40 paces) from any water source or trail.

Two - a few permits require you to stay in a “backcountry camp” on your first night - after which you are free to camp anywhere rules allow.

• Happy Isles to Little Yosemite Valley - also known as LYV
• Glacier Point to Little Yosemite Valley
• Glen Aulin

Other than these limits, you can camp almost anywhere in the wilderness. That's the real beauty of Yosemite's dispersed camping rules.

Unlike parks that funnel you into designated backcountry sites - which can feel a lot like a campground with a prettier view - dispersed camping means you choose your own spot. A high basin overlooking unnamed lakes. Nestled in a forest with granite monoliths filling the view. Somewhere you actually had to walk to reach.

How to Get Yosemite Backpacking Permits (The 4 Windows)

Yosemite wilderness permits become available through four separate mechanisms.

Understanding all four is how you actually get a permit.

Window 1: The Lottery (60% of Permits - 24 Weeks Out)

The majority of permits are distributed through a rolling weekly lottery on Recreation.gov.

Applications open every Sunday and close the following Saturday, covering start dates 24 weeks in the future.

Lottery results are released on Mondays. If you win, you have until Thursday 11:59 PM Pacific Time to claim the permit before it disappears.

Cost: $10 per application, plus $5 per person if you win.

Here are a few popular holiday dates put into real terms

• Memorial Day - lottery is mid-November
• Fourth of July - lottery is early January
• Labor Day - lottery is mid-March

Most people aren't thinking about May backpacking in November - but the people who are knowledgeable about wilderness permit scarcity are already planning their spring backpacking.

If you already missed these windows for the current year - make a mental note for next year.

Pro tip: Flexibility dramatically improves your odds. Be willing to adapt your plans. The lottery application allows you to submit eight trailhead and date combinations. Use that to your advantage:

• Apply for multiple trailheads - and target less popular trailheads
• Use the date-range option instead of single days. Pick a few days before and after your desired date - or pick the entire week.
• Put your preferred date as your first choice combination - then second/third/etc put the wider range in. This way if your preferred date is available, you get it - and the wider range catches everything else.

Window 2: Lottery leftovers and cancellations

Whatever permits remain after that week’s lottery - are released Friday at 9:00 AM Pacific Time. (The leftovers)

These permits remain available until three days before the trip start date, or until someone grabs them.

Given that the lottery happens 24 weeks in advance - there are often cancellations. People will outright cancel or reduce the number of people on their permit. Cancelled permits return to the pool. And as each weekly lottery completes the number of potential cancellations increases.

Pro tip:

Permits which are canceled do not immediately return to the pool. Recreation.gov (not Yosemite) randomizes the time when canceled permits return to the available pool. If your buddy cancels their permit and you plan to login right then and grab it - it is highly likely you won’t see it become available. Permits get released back into the pool at some random point within 24 hours.

If you monitor Recreation.gov regularly, trips that looked completely unavailable can suddenly reappear - at any time of day or night.

This window rewards preparation and persistence plus a little bit of luck.

Window 3: The 7-Day Release (40% of Permits)

The remaining 40% of each trailhead’s daily quota is held back entirely from the lottery.

This pool of permits is referred to as “walk-up” however they are released on Recreation.gov - not in-person.

These permits are released exactly seven days before the trip start date at 7:00 AM Pacific Time.

For high-demand trailheads in peak season, they disappear almost instantly.

Not minutes.

Seconds.

If you’re targeting one of these permits, you need to be:

• Logged into Recreation.gov
• Already know party size
• Preferred and Backup Trailheads already chosen
• Cursor hovering over the button to hit refresh of the page

When the clock hits 7:00:00, you click.

Even a delay of a few seconds can mean the difference between success and a fully booked trailhead.

Sometimes it can take a second refresh of the browser for them to appear. Be quick!

Window 4: In-person walk-up

Any permits which have not been claimed in the previous windows become locked 3 days prior to the actual date of the permit.

At this point Recreation.gov will no longer allow you to book them on-line even if they are available.

Additionally - people who had permits previously could cancel during this window and the number of available permits could increase.

To obtain a “true walk-up permit” - you should be at a wilderness permit issuing station at 8am the day before your trip starts. There is often a line of people waiting to get permits so you should consider arriving much earlier to be closer to the front of the line.

Pro tip: Some of the people who line up may not be seeking a walkup and simply want to pick up their already-reserved permit at 8am and move on with their day. Not everyone in line is your competition.

You can also get a walk-up permit on the day of your planned start. It might seem likely that at this point everything is gone for the best trailheads. However more last minute cancellations can happen or the people who picked up the day prior could have reduced their number of people and freed up permit slots for the best trailheads.

There is one last place where permits can suddenly become available - at 11am on the day of - any permits which are not picked up become available to anyone.

The true walk-up method can be where hopes and dreams come true - and you get that Happy Isles permit with the Half Dome stamp. Or it could be where you find yourself talking through various options with a permit ranger trying to figure out where you can go within the remaining available permits.

If you are planning to get a true walk up - show up with 5-8 trailheads in mind. Don’t expect the ranger to plan your trip for you. They will tell you what is available and may offer suggestions, but you’ll need to figure out how you will use the permit you get. Come prepared with your own Yosemite backpacking map (Nat Geo), pen and paper to take notes on any suggestions rangers give you.

Yosemite Backpacking Permits for Half Dome

Half Dome is one of the most popular destinations in the park - so much so that NPS has implemented a quota of 300 people per day for Half Dome Cables access. 225 are allocated to Day Hikers and the remaining 75 are allocated to backpackers.

Not all wilderness permits are valid for Half Dome. Only these trailheads:

• Happy Isles to Little Yosemite Valley
• Happy Isles past Little Yosemite Valley
• Glacier Point to Little Yosemite Valley
• Sunrise Lakes
• Cathedral Lakes
• Rafferty Creek to Vogelsang
• Mono Meadow

If you hold a permit for any of these trailheads you are allowed to summit Half Dome via the cables one time during your wilderness trip. The day you summit is your choice not fixed or defined by the permit.

Pro tip:

• If you have a permit for one of these trailheads you still need to inform the ranger when picking up your permit that you plan to access Half Dome. Permit staff will usually ask you. A $10 per person fee is required then to add Half Dome on to the permit.
• Be sure to bring your ID with you that matches the name on your wilderness permit to Half Dome as a ranger will expect you to have both when you arrive at Sub Dome.
• Bring grippy gloves. Your hands will thank you.

So What Does a Permit Actually Get You?

A wilderness permit is just a piece of paper.

But what it unlocks is something very different.

You start the day like everyone else in Yosemite - parking lots filling, trailheads busy, hikers heading out with daypacks and cameras.

And then you keep walking.

You pass the turnaround points. The crowds thin. The trail grows quieter.

By mid-afternoon, the rhythm of the park changes. The noise fades. The granite walls feel larger. The landscape opens up in a way that day visitors rarely see.

You find a place to camp somewhere you had to earn.

You filter cold water from a creek that still runs clear in August. You cook a simple meal while the evening light moves slowly across the granite.

And in the morning, you wake up already there.

Already inside a version of Yosemite that most visitors only glimpse from an overlook before driving back to the Valley.

That’s what a wilderness permit unlocks.

Not just access.

Perspective.

How to Skip the Lottery: Guided Trips

At this point you have two options.

You can learn the permit system and try to secure one yourself. Or you can skip the process and join a trip where the permit is already handled.

Both are valid paths.

Here’s what each one looks like.

Path 1: Secure Your Own Permit

If you want to navigate the permit system yourself, here’s the basic playbook.

Create a Recreation.gov account now

Get familiar with the interface before you need it. The release windows move too fast to be learning the website on the fly.

Apply for the preseason lotteries

Follow all the guidance to increase your odds.

Watch for cancelations

Check often,

Set alarms for the various Rec.gov release windows

Have everything figured out before the screen refreshes. Seconds matter.

Stay flexible

The people who consistently get permits are the ones willing to shift trailheads or dates when their first choice falls through.

With persistence, preparation, and a little luck, you can absolutely make it happen.

Path 2: Start With a Permit Already Secured

For the 2026 season, I've already secured seven Yosemite wilderness permits. If you want to skip the lottery and join one of my Guided Yosemite Backpacking Trips, the hardest part is already done.

If you want to experience Yosemite’s backcountry this year without spending months refreshing Recreation.gov, come join me.

You just have to show up.

A Final Note

The permit system can feel frustrating.

But it exists for a reason.

Yosemite’s wilderness is fragile, irreplaceable, and worth protecting.

Go in with that mindset.

Follow Leave No Trace principles. Camp away from water sources. Pack out everything you bring in.

Yosemite’s backcountry rewards people who treat it with the respect it has earned.
