In this guide, we cover why you need a permit and how to get one.

Why Do You Need a Permit?

Since 2010, the National Park Service has required hikers to have a permit to climb Half Dome.

Before 2010, overcrowding on the cables created a dangerous situation. On peak days before 2010, there would be as many as 1,200 daily visitors to Half Dome. In the past decade, several people have died climbing the Half Dome cables.

Now, only 300 people per day are allowed to climb Half Dome, and to do so, you must have a permit.

So, how do you get to be one of the lucky permit holders?

How to Get a Half Dome Permit

Preseason Lottery

Permits are awarded in a preseason lottery for the entire summer hiking season.

During a typical year, a maximum of 300 permits are awarded per day, with 225 for day hikers and 75 for backpackers.

Applications are accepted during the month of March (from March 1 through March 31), regardless if you are hiking in June or September.

On the application, one person (called the team leader) can apply for up to six people for a series of dates. The team leader is only allowed to apply once per lottery. If you apply multiply times, all of your applications will be removed from the lottery.

The trip leader or the alternate person listed on the application must be present at the sub-dome when the permits are checked. The permits are not transferable to other hikers.

It costs $10 to file an application, regardless of the number of people listed on the application.

IMPORTANT: Applicants may be a permit holder (trip leader) or alternate on only one application during the preseason lottery. Your name can only appear on one application, whether or not you are the trip leader OR the alternate. If your name appears on more than one application, all of your lottery applications will be cancelled.

The lucky lottery winners are notified mid-April.

Once you are notified by email, you then have to two weeks (until mid-May) to pay the $10 per person for the permit. The permit is refundable.

To get more information, visit the National Park Service website.

To file an application, visit the recreation.gov website. If you have questions, give them a call at 877-444-6777.

What if you plan to visit Half Dome with kids? The youngest age we would recommend is 12 years old, and that is only if your child has lots of prior hiking experience and is very physically fit. When I spoke to the supervisor at recreation.gov, they told me that children can be listed on the permit application. I was told that there was no minimum age. However, if your child is listed on the permit, you will need to bring a government-issued ID as their form of identification.

Daily Lottery

Permits are awarded on a daily basis, and this number depends on cancellations of other permits and no-shows on the trail. You can apply online for these permits two days before your anticipated hiking date. Visit recreation.gov to file your application for a daily permit.

What Are Your Chances of Getting a Permit?

As the Half Dome hike grows in popularity, your chance of scoring a Half Dome permit decreases.

In 2016, there was a 25% chance you would be awarded a permit. Compare that to 2015, with a 35% success rate and 2014 with a 45% success rate.

In 2017, there were 26,963 applications, with a 25% success rate. We hiked Half Dome in 2017.

Does this sound discouraging?

In more recent years, your chances of getting a Half Dome permit actually improved, with a 28% success rate in 2019 and a 36% success rate in 2020. But we all know that 2020 was not a normal year. In 2022, there was a 22% chance you’d get a preseason permit.

To get a permit, you do need to be lucky, but there are some ways you can increase your chances.

If you can be flexible in your travel dates, you can greatly increase your odds of being one of the lucky permit holders.

Monday through Thursday are much less popular than Friday, Saturday, or Sunday. It’s almost impossible to get a permit for Saturday.

The few days from July 4 through July 8 tend to have slightly smaller crowds than the other times of the summer (and fewer applications for the Half Dome cables). This is the time that we visited Yosemite. On July 5, crowds were manageable, but by July 7 the park was getting very crowded again. Consider taking advantage of the July 4 holiday and hiking Half Dome if you have plans to visit Yosemite during the summer months.

September and October are the months with the fewest number of applications so it is easier to get a permit. In general, Yosemite will be a little quieter during this time also, since summer holidays are over.

If you are unsuccessful in getting a pre-season lottery ticket, you can apply for a daily lottery ticket, which is awarded two days before your anticipated hiking date.

Where am I getting all of these numbers? The National Park Service website has excellent data on lottery applications and success rates for the entire season. If you want to plan your Yosemite trip around your best odds for getting a Half Dome permit, I highly recommend that you take a look at their lottery statistics.

Hiking Without a Permit

What if you want to take your chances and hike without a permit? Rangers on the trail check permits just before the sub-dome and at other spots along the trail.

If you hike Half Dome without a permit, you risk paying a $5,000 fine and/or 6 months in jail.
