Half Dome stands as one of the most iconic hikes in all of North America. Rising nearly 5,000 feet above Yosemite Valley, the granite crest draws thousands of hikers each season who dream of pulling themselves up the famous cables to the summit.
But here is the truth that catches most people off guard: getting to the trailhead is the easy part. Securing a Half Dome permit is the real challenge. In the 2024 season, only 18% of preseason lottery applicants walked away with a permit. The system is competitive, confusing, and unforgiving if you miss a deadline.
That is exactly why we put together this guide. We walk you through exactly how to apply for a Half Dome permit, break down both lottery systems, explain the fees, and share what to do if you do not win. By the end, you will have a clear plan for checking Half Dome off your list in 2026.
Whether you are a first-time applicant or someone who has been trying for years, the strategies below are based on real hiker experiences, official National Park Service guidance, and data from Recreation.gov.

Do You Need a Permit for Half Dome?
Yes, you need a permit to hike beyond the subdome and use the Half Dome cables during the cables-up season. No exceptions are made for day hikers.
When Are Permits Required?
The cables-up season typically runs from Memorial Day weekend through mid-October (around Columbus Day). During this window, the National Park Service installs and maintains the cable handrails that allow hikers to ascend the final 400 feet of steep granite to the summit.
The Park Service limits the number of hikers to 300 per day on Half Dome during this period. About 225 of those permits go to day hikers distributed through the lottery system. The remaining 75 are reserved for backpackers holding wilderness permits.
A ranger station sits at the base of the subdome, and rangers check every permit before allowing anyone to continue up the cables. You cannot bypass this checkpoint on the standard route.
What Happens If You Hike Without a Permit?
Hiking Half Dome without a permit during cables-up season can result in fines of up to $5,000 and a mandatory court appearance. Rangers actively patrol the checkpoint, and there is no way to sneak past on the traditional hiking route.
The rules exist for good reason. The 300-hiker daily cap protects the trail environment and reduces dangerous crowding on the cables, where a single slip can be fatal.
What About When the Cables Are Down?
From approximately mid-October through late May, the Park Service removes the support boards from the cables and lays them flat against the rock. During this cables-down period, no permit is required to hike the Half Dome trail.
However, attempting the summit without the cable stanchions and support boards is extremely dangerous. Snow, ice, and wet granite make the final ascent treacherous even for experienced mountaineers. Most knowledgeable hikers strongly advise against it unless you have technical climbing skills and proper equipment.
If you are wondering what to do when the cables are down, the answer is simple: enjoy the hike to the subdome, but save the summit for cables-up season when you can secure a permit and climb safely.
The Preseason Lottery: Your Best Shot at a Half Dome Permit
The preseason lottery is the primary way to secure a Half Dome permit for day hiking. It gives you the best odds and lets you plan your trip months in advance.
When to Apply
The preseason lottery application window opens on March 1 and closes on March 31 each year. You can submit your application at any point during this 31-day window.
The timing of your application within the window does not affect your odds. Applying on March 1 gives you the same chance as applying on March 31.
Results are announced in mid-April, giving you roughly six weeks to finalize travel plans before the cables-up season begins around Memorial Day weekend.
How the Preseason Lottery Works
You apply for specific dates during the hiking season. The system lets you rank your preferred dates in order of priority.
Each application costs a $10 non-refundable fee, regardless of whether you win or lose. If you are awarded a permit, you pay an additional $10 per person per hiking day.
The lottery draws randomly from all applications for each date. Since demand varies by date, applying for less popular dates increases your chances of winning.
Group Size Rules
The preseason lottery allows group sizes of up to 6 people per application. You must list every group member by name at the time you apply.
One person serves as the trip leader, and you can also designate an alternate permit holder. This alternate can claim the permit at the trailhead if the original trip leader cannot make it. Both individuals must be listed on the application.
Forum discussions from Yosemite hikers on Reddit reveal an interesting insight: group size does not significantly affect your odds. A group of 6 has roughly the same chance of winning as a solo hiker for the same date. The lottery evaluates based on the application, not the number of people on it.
Preseason vs Daily Lottery Comparison
| Feature | Preseason Lottery | Daily Lottery |
|---|---|---|
| Application window | March 1 to March 31 | 2 days before hike date |
| Results announced | Mid-April | Same day, early evening PT |
| Application fee | $10 non-refundable | $10 non-refundable |
| Per-person cost if awarded | $10 per person per day | $10 per person per day |
| Max group size | 6 people | 6 people |
| Best for | Planning ahead | Flexible or in-park trips |
| Overall odds | ~18 to 20% | Lower, varies by day |
The Daily Lottery: Last-Minute Half Dome Permits
The daily lottery is your second chance at a Half Dome permit. It distributes a portion of the 225 day-hiker permits roughly 48 hours before each hiking day.
How the Daily Lottery Works
You apply exactly two days before your intended hike date. The application window opens at midnight Pacific Time and closes at 1:00 PM Pacific Time on that day.
Results are posted later the same day, usually by early evening. If you win, you receive a permit for the following day.
For example, if you want to hike Half Dome on a Friday, you would apply on Wednesday between midnight and 1:00 PM PT. Results come back Wednesday evening.
When to Use the Daily Lottery
The daily lottery is perfect for people already in Yosemite or planning a flexible trip. If you are camping or staying in the area for several days, you can enter the daily lottery multiple times during your stay.
Many successful hikers on Reddit report entering the daily lottery three or four times during a week-long trip. Even if you lose the preseason lottery, the daily lottery gives you several more shots at a permit.
One important note: daily lottery odds are generally lower than preseason odds for popular dates. However, weekday daily lottery entries can have surprisingly good success rates because demand drops off significantly from weekend peaks.
Fees for the Daily Lottery
The daily lottery uses the same fee structure as the preseason lottery. You pay $10 per person at the time of application, and if you do not win, that per-person amount is refunded to your card.
A $10 non-refundable application fee is charged per application regardless of the outcome. This fee covers the administrative cost of processing the lottery entry.
Step-by-Step Guide to Applying for a Half Dome Permit
Applying for a Half Dome permit follows the same process for both lotteries through Recreation.gov. Once you create an account, the steps are straightforward.
Step 1: Create a Recreation.gov Account
Go to Recreation.gov and set up a free account before the lottery opens. Use an email address you check regularly, because all notifications and permit confirmations go there.
Having your account ready in advance saves precious minutes when the daily lottery window opens. Add your credit card to your profile so payment is quick.
Step 2: Find the Half Dome Permit Page
Search for “Half Dome Permits” on Recreation.gov, or navigate directly to the Half Dome permit page using the permit ID 234652. This page hosts both the preseason and daily lottery applications.
Make sure you select the correct lottery type. The preseason lottery is only available during March, and the daily lottery appears during the hiking season.
Step 3: Submit Your Preseason Application
During the March 1 to March 31 window, select your preferred hiking dates in priority order. Enter all group member names, designate a trip leader, and add an alternate permit holder.
Pay the $10 non-refundable application fee with a valid credit card. Double-check your payment method before submitting.
Forum users frequently report losing permits due to payment processing failures or expired cards on file. This is one of the most frustrating ways to lose a Half Dome permit, and it is completely preventable.
Step 4: Submit Your Daily Lottery Application
Two days before your target hiking date, log into Recreation.gov between midnight and 1:00 PM Pacific Time. Select your hiking date and enter your group member names.
Submit your application and pay the required fees. Results come back the same day, typically by early evening.
If you win, print or download your permit confirmation immediately. Do not wait, because technical glitches can make it harder to retrieve later.
Step 5: Print and Bring Your Permit
For preseason permits, you can print your permit at home. Check the instructions in your confirmation email for details.
Bring a government-issued photo ID that matches the name on the permit. Rangers check IDs at the subdome checkpoint, and the name must match exactly. If your name is listed as the trip leader or alternate, you must be the one who presents the permit.
What to Do If You Don’t Win a Half Dome Permit
Not winning the preseason lottery is not the end of your Half Dome dreams. Several backup strategies exist, and many hikers summit each year without winning the preseason lottery.
Strategy 1: Enter the Daily Lottery
This is the most common fallback. If you are already in Yosemite, enter the daily lottery for each day of your visit.
Many hikers report that entering for weekday dates rather than weekends significantly improves daily lottery odds. Tuesday, Wednesday, and Thursday tend to have the best success rates because demand drops off sharply.
If you have a week in the park, you effectively get five to seven chances through the daily lottery. That compounds your odds considerably compared to a single preseason entry.
Strategy 2: Get a Wilderness Backpacking Permit
Backpackers with wilderness permits that include Half Dome on their itinerary get automatic access to the cables. You do not need a separate day hiking permit if your wilderness permit covers the Half Dome area.
The catch is that you must be on a multi-day backpacking trip with an itinerary that routes through the Half Dome corridor. These wilderness permits are also distributed through Recreation.gov and have their own lottery system.
Little Yosemite Valley is the most common base camp for backpackers tackling Half Dome. If your wilderness permit includes a night in Little Yosemite Valley, you are typically granted Half Dome cable access for the day you summit.
Strategy 3: Find Groups With Spare Permits
This is a well-known Yosemite tradition. Hikers who win permits sometimes have group members drop out at the last minute, leaving open spots on their permit.
Arrive at the trailhead or Happy Isles early in the morning. Ask groups if anyone has extra permit spots. Rangers will allow you to join if your name can be added to the permit before you reach the subdome checkpoint.
This approach is not guaranteed, but it works often enough that multiple Reddit and Facebook users report succeeding this way. Being friendly, arriving early, and being honest with rangers goes a long way.
Strategy 4: Hike to the Base of the Subdome
Even without a permit, you can hike all the way to the top of Nevada Fall and the base of the subdome. The Mist Trail and John Muir Trail are spectacular on their own, offering some of the best scenery in Yosemite.
You simply cannot go past the permit checkpoint at the subdome without a valid permit. But many hikers find this partial hike deeply rewarding even without the cable ascent to the summit.
The hike to Nevada Fall is about 5.4 miles round trip from the Happy Isles trailhead. Adding the trek to the subdome base extends it to roughly 7 miles one way, giving you a serious workout with stunning views.
Strategy 5: Target Shoulder Season Dates
September and October see fewer applicants in both lotteries. The weather is still pleasant for hiking, and wildfire risk often decreases compared to August.
If your schedule is flexible, targeting late-season dates gives you a statistical edge. October dates before the cables come down can have significantly lower competition than June or July dates.
Strategy 6: Try Again Next Year
The lottery resets every March. If you missed out this year, start fresh with a new preseason application in March 2026.
Many hikers win on their second or third attempt. Persistence pays off, especially if you refine your date strategy each year based on what you learn.
Use your unsuccessful attempt as a learning experience. Apply for weekdays instead of weekends, spread your date choices across different months, and keep your payment information current.
Tips to Boost Your Half Dome Permit Odds
Beyond simply entering the lottery, a few strategic choices can meaningfully improve your chances of winning a Half Dome permit.
Choose Weekdays Over Weekends
Weekend dates are dramatically more competitive than weekdays. If you can hike midweek, your odds improve significantly.
Friday, Saturday, and Sunday see the highest demand in both the preseason and daily lotteries. Tuesday through Thursday consistently show better success rates.
If you must apply for a weekend, Sunday tends to be slightly less competitive than Saturday because many visitors leave the park on Sunday morning.
Target Shoulder Season
June and September offer a sweet spot of good weather and lower competition. Early June trails the busy Memorial Day rush, and September sees summer crowds thin out as schools resume.
July is peak season with the highest demand. If you can avoid it, your odds improve by shifting to June or September dates.
Avoid Peak Wildfire Months
August is historically the worst month for air quality in Yosemite. Wildfire smoke can make the hike unhealthy or even force trail closures.
Even if you win a permit for August, there is a real chance smoke could ruin your trip. June and early July tend to have clearer skies and more reliable conditions.
Check the AirNow fire and smoke map before committing to specific dates. This is especially important if you are traveling from far away and have limited flexibility.
Keep Your Payment Information Current
This cannot be stressed enough. Multiple hikers on Reddit and in Yosemite Facebook groups report winning the lottery only to lose the permit because their card was declined or had expired.
Update your Recreation.gov payment method before the lottery opens each March. Verify your card is still valid when results come out in mid-April.
For the daily lottery, check your payment info before each entry. A declined card means an instant loss, even if your application was selected in the draw.
FAQs
How difficult is it to get Half Dome permits?
Getting a Half Dome permit is quite difficult. In the 2024 season, only about 18% of preseason lottery applicants won a permit. Weekend dates are even more competitive, with some dates seeing success rates below 10%.
What are the odds of getting a Half Dome permit?
Overall preseason lottery odds are roughly 18 to 20%, or about 1 in 5 applications. Weekday dates can reach 25 to 35% success rates, while popular weekend dates often drop below 10%. The daily lottery has generally lower odds but can be entered multiple times during a trip.
What happens if you hike Half Dome without a permit?
Hiking Half Dome without a permit during cables-up season can result in fines up to $5,000 and a mandatory court appearance. Rangers actively check permits at a checkpoint at the subdome base, and there is no alternate route to bypass the check.
How hard is it to get a permit to hike Half Dome?
It is challenging but not impossible. While the overall success rate hovers around 18 to 20%, entering the daily lottery during your trip and targeting weekday dates can push your personal odds much higher. Many hikers succeed within one or two seasons of trying.
When should I apply for a Half Dome permit?
For the preseason lottery, apply anytime between March 1 and March 31. The timing within that window does not affect your odds. For the daily lottery, apply exactly two days before your desired hiking date between midnight and 1:00 PM Pacific Time.
Can you get a Half Dome permit without the lottery?
Yes, through a wilderness backpacking permit. If your multi-day backpacking itinerary routes through the Half Dome area, you receive automatic cable access without a separate day hiking permit. Wilderness permits are distributed through Recreation.gov and have their own lottery system.
Do you need a permit for Half Dome when the cables are down?
No permit is required when the cables are down, roughly from mid-October through late May. However, hiking the cables route without the stanchions and support boards is extremely dangerous and not recommended for most hikers due to snow, ice, and exposure.
Conclusion
Getting a Half Dome permit requires patience, strategy, and a backup plan. The preseason lottery in March is your best shot, and the daily lottery during your trip is a solid fallback.
If neither works, wilderness backpacking permits, early-morning permit hunting, and shoulder-season flexibility all keep the summit dream alive. Knowing how to apply for a Half Dome permit and what to do if you do not win is what separates the hikers who eventually summit from those who give up after one attempt.
