How to Get a Mt. Whitney Permit

Whitney is the highest thing you can stand on in the Lower 48 (a ~22-mile round trip with over 6,200 feet of climbing) and on a clear August morning the summit register fills up with people who look genuinely surprised they made it. Here’s the part nobody warns you about: the mountain is the easy half. The permit is what breaks people.

Tens of thousands apply every year. In 2023 there were about 26,000 applications, roughly 110,000 people, chasing a daily quota of 100 day hikers and 60 backpackers, which across the May-to-November quota season adds up to somewhere near 30,000 people’s worth of permits. So the lottery as a whole isn’t the bloodbath it gets described as: about one application in four comes away with something. The bloodbath is date-specific. If your heart is set on the first weekend of August, you’re closer to one in a hundred.

But losing the lottery isn’t the end of the story. Most people just think it is, close the tab, and go hike something else. This guide is about not doing that: how the permit works, what the odds really look like, and the three ways to still get on the trail after the lottery says no.

Mt. Whitney permit, in one breath

• Covers: the Mt. Whitney Trail from Whitney Portal, day hikes and overnight trips. A permit is required year-round; May 1 – November 1 is the quota season, when the lottery and the daily caps apply.
• Daily quota: 100 day hikers, 60 overnight backpackers, in quota season only.
• Off-season: from November 2 to April 30 there’s no quota at all. Permits are unlimited and you reserve up to two weeks out. It’s a winter mountaineering objective by then, which is why almost nobody mentions this.
• How you get one: an annual lottery, then a first-come release of everything the winners didn’t claim, then cancellations trickling back all season.
• Where: Recreation.gov, permit #445860 (Inyo National Forest).
• Walk-ups: none. This matters more than it sounds. We’ll come back to it.

How the lottery works

The front door is the annual lottery on Recreation.gov, and it runs on a tight schedule.

You apply February 1 through March 1. Apply whenever you like in that window. Going in on February 1 buys you nothing, so don’t stress the timing. You’ll choose day-use or overnight, an entry date, your group size (up to 15), and up to three alternate leaders in case the main leader can’t make it.

Results land in your account on March 15. If you win, you’re not done: you have to go back in and formally claim the permit, and pay, by 9 p.m. Pacific on April 21. Miss that deadline and it evaporates, which is a genuinely tragic and genuinely common way to lose a permit you already won.

The money: $6 to enter the lottery (you don’t get it back), and $15 per person if you win and claim.

Day hike or overnight? Day-use permits cover a single midnight-to-midnight date and can’t be strung together across days. So if you’re planning to camp (Outpost Camp, Trail Camp, or continuing onto the John Muir Trail) you want an overnight permit, not two day permits.

The odds, and the one thing you control

It’s tempting to talk about “the odds of a Whitney permit” like it’s a single number. It isn’t. Across all dates and both permit types, roughly a quarter of applications win something, better than most people assume, and worth knowing before you talk yourself out of applying. But that average is close to useless on its own, because Whitney is really hundreds of tiny lotteries, one per date, and they swing enormously:

• Peak dates (summer weekends, and the first weekend of August above all) can sit around 1%.
• Shoulder dates (weekdays, plus May, June, late September, and October) are a completely different game, sometimes better than even odds.

The lever in your hands is flexibility. Swapping an August Saturday for a late-September Wednesday can take you from “buying a lottery ticket” to “probably going.” If you actually want to stand on the summit more than you want to stand on it on a specific holiday weekend, apply for the quiet dates. That single choice beats every other trick combined.

Didn’t win? You’ve still got three shots, and one nobody counts

Here’s the section we wish more guides led with, because it’s where the permits actually are for most people.

1. The unclaimed release: April 22. Remember all those winners who forget to claim by April 21? Everything they leave on the table goes back on sale to everyone, first-come, at 7 a.m. Pacific on April 22, and it keeps selling for the rest of the season while it lasts. Be logged in, be early, and know your dates before the clock hits.

2. Freed-up spots: all season, every day. This is the big one, and it’s the one almost nobody works. From May 1 to November 1, freed-up permits go back onto Recreation.gov at unpredictable times, right up until the days before a trip. Here’s the mechanism people miss: Whitney permits are non-refundable, so instead of clean cancellations, most of the movement comes from group leaders trimming their party size in the week before they go (the moment a group of six becomes a group of four, two spots quietly reappear) plus no-shows and last-minute drops. Either way, the spots return to rec.gov for whoever’s watching.

3. Group-size drops. Same idea as above, worth saying plainly: when a permitted group shrinks, the freed spots go back into the pool.

4. The door nobody counts: the off-season. Outside the quota season, November 2 through April 30, there is no lottery, no daily cap, and no scramble: the number of permits issued is unlimited, and you reserve up to two weeks ahead. We’re not going to pretend that’s a like-for-like swap. That’s a winter ascent of a 14,000-foot peak, with every bit of skill and gear that implies. But if you’re equipped for it, the permit problem simply stops existing, and it’s worth knowing the door is there.

Now the catch, and it’s a real one. Remember “no walk-ups”? It means there is no backup plan at the trailhead. In quota season, the lottery, the April 22 release, and freed-up spots are the only ways onto that trail. And those openings are invisible unless you happen to be staring at Recreation.gov the exact minute one appears, then fast enough to grab it before the next person does. Refreshing the page forty times a day isn’t a strategy; it’s a way to lose a weekend.

This is the specific, tedious problem BigDirtyHikes exists to solve. We watch the Whitney permit on Recreation.gov for you and ping you the instant a spot opens for your dates, so you’re the one who sees it first. You still book it yourself. We just make sure you’re not the person who found out ten minutes too late.

The mistakes that cost people the mountain

• Treating the lottery as the whole game. The April 22 release and season-long cancellations put a lot of people on the summit. If you stop trying in March, you’ve quit before the good part.
• Only entering peak weekends. Add midweek and shoulder-season dates. It’s the highest-leverage thing you can do, and it’s why the overall one-in-four figure and the one-in-a-hundred August figure can both be true.
• Blowing the April 21 claim deadline. Winning and then forgetting to pay is the saddest way to lose a permit. Set a reminder the day results post.
• Banking on walk-ups. There aren’t any. Don’t drive to Lone Pine on a prayer.
• Forgetting the permit is step one. The mountain still wants over 6,200 feet of climbing and a summit over 14,500 feet, most of it before the afternoon storms. Which is the part we can actually help with once your date’s locked.

You’ve got the date. Now build the pack.

A Whitney permit is the hard-won part, but a 22-mile day at altitude will punish a sloppy pack. That’s exactly what the BigDirtyHikes pack builder is for: build your Whitney pack, watch the weight add up in real time, and pull from a gear closet you reuse trip after trip. The lighter your load at 3 a.m. leaving the Portal, the better your odds of standing on top instead of turning around at Trail Crest.

Official sources (bookmark these)

Everything above is checked against these. If we ever disagree with them, they’re right and we’re wrong. Tell us and we’ll fix it.

• Recreation.gov permit #445860. The permit itself. Lottery dates, quotas, fees, and the season rules all come from here. This is also where you apply and where freed-up spots reappear.
• Inyo National Forest: Mount Whitney. The managing forest’s own page. Best source for the quota-season boundary and the unlimited off-season window.
• Inyo National Forest: wilderness. Trailhead quotas beyond Whitney, bear canister rules, and the wider wilderness permit system if you’re linking Whitney into a longer trip.
• Inyo National Forest: alerts and closures. Fire closures, road status, and trail conditions. Check this the week you go, not the month you book.

Why trust this guide

Untangling how Recreation.gov actually releases, holds, and returns permits (including the cancellation timing above) is the whole of what we do here. If a date on this page is ever wrong, tell us and we’ll fix it fast. Accuracy is the entire point.

Frequently asked questions

When does the Mt. Whitney lottery open? Applications run on Recreation.gov from February 1 to March 1 each year, with results on March 15.

How much does a Mt. Whitney permit cost? $6 to enter the lottery, plus $15 per person if you win and claim it.

Can I get a Mt. Whitney permit without winning the lottery? Yes, and plenty of people do. Unclaimed permits go on sale first-come on April 22, and freed-up spots (from group-size reductions, no-shows, and drops) return to Recreation.gov all quota season, May 1 to November 1. There are no walk-up permits. Outside the quota season, November 2 to April 30, no lottery is involved at all. Permits are unlimited and reserved up to two weeks ahead, though that means a winter ascent.

What are my odds in the lottery? Overall, about one application in four wins something, better than Whitney’s reputation suggests. But it swings enormously by date: peak summer weekends can sit around 1%, while midweek and shoulder-season dates are sometimes better than even odds. Flexibility is the biggest factor you control.

Do I need a permit just to day hike Whitney? Yes, year-round. Every trip on the Mt. Whitney Trail needs a permit, day hikes included. May 1 to November 1 is the quota season, when the daily caps and the lottery apply; the rest of the year permits are unlimited.
