Half Dome vs Mount Whitney: Which Lottery Is Harder?

Two of California’s most iconic summits share one frustrating trait: you cannot just show up and climb them. Half Dome in Yosemite and Mount Whitney — the highest peak in the lower 48 states — both run quota systems on recreation.gov, and both are fought over in annual winter lotteries. But they are not the same game. One is a day-hike lottery with a deep fallback pool; the other is a mountaineering-style quota with a hard physical entry barrier. This comparison breaks down the mechanics, the odds, the costs, and how a driven hiker can play both at once.

If you are choosing your 2027 Sierra bucket-list peak or trying to decide where to spend your February–March lottery energy, read on.

2027 exact dates are not yet posted as of October 2026; the schedule mirrors 2026 closely, so treat these as the planning baseline and reconfirm on recreation.gov in January.

Mechanic 1: Half Dome’s preseason draw

The Half Dome cables run roughly from late May through mid-October, and the preseason lottery is your main shot at a date inside that window. You open the application on March 1, enter up to seven possible dates, indicate whether you are day-hiking or backpacking, and pay the $10 non-refundable fee. Winners are drawn randomly in mid-April and then have a short payment window to claim their permits at $10 per person.

The critical safety net is the daily lottery two days before each hike. Any permits not claimed in the preseason draw, plus cancellations, recycle into this smaller, rolling game. Because Yosemite also has the cable route exposed to thunderstorms, many permits get returned during stormy summers — which feeds the daily pool. A hiker on the ground in Yosemite Valley with flexible days can often snag a Half Dome permit here on a weekday even after losing the preseason draw.

Mechanic 2: The Whitney Zone lottery

Mount Whitney operates under the United States Forest Service’s Mount Whitney Zone quota, a far tighter system. The lottery opens February 1 and closes March 1; results post around March 15; winners must claim by April 21, and anything unclaimed goes back on sale April 22. The $6 application fee is cheap, but the recreation fee jumps to $15 per person for any overnight or day use inside the Whitney Zone between May 1 and November 1.

There is no meaningful day-before fallback. The total quota — about 100 day-use and 60 overnight permits per day combined — is simply smaller, and demand from California peak-baggers is relentless. Outside the quota season (roughly November through April), the mountain is open without a permit, but that means winter conditions: ice, snow, crampons, and an entirely different expedition than a summer day hike.

Which lottery is actually harder?

By pure numbers, Whitney is harder to win for a summer overnight. Estimated odds run 15%–30% for a weekday slot but drop below 5% for a July weekend overnight — precisely the slot most people want. Half Dome preseason odds of 15%–30% sound similar, but remember the daily two-day lottery sits underneath it, meaning the true chance of getting onto the cables on a given summer weekday is meaningfully higher than the preseason percentage suggests.

The deeper difference is physical. Half Dome is a big day hike — 14–17 miles round trip from the Valley floor, with 4,800 feet of climbing — but it is achievable by a fit hiker with training. Whitney is a 22-mile (or longer) round trip from Whitney Portal, crossing 99 switchbacks and reaching 14,505 feet. Most day-hike Whitney permits go to people who have done serious alpine preparation, and altitude illness is a real risk even for acclimated hikers. So the "harder" question splits: winning Whitney’s lottery is slightly harder in peak season, but doing Whitney is harder in almost every physical sense.

Date and cost strategy

• For Half Dome, prefer mid-week dates in June or September. July and August weekends are the most oversubscribed; the shoulder windows before and after summer draw far fewer applicants per cable permit.
• For Whitney, prefer weekday overnight slots early or late in the season (May or October), when the snow-free trail is shorter and casual peak-baggers stay home. Mid-summer weekends are the worst-value entries.
• Budget honestly. Half Dome round-trip fees are about $20 per person; Whitney is $6 + $15 = $21 plus the Inyo National Forest Adventure Pass or America the Beautiful pass for the portal parking area.
• Set a calendar reminder for April 22. That is when unclaimed Whitney permits are released — a second chance many applicants forget about entirely.

The dual-apply strategy

Here is the practical play. Both lotteries fall in the same window: Half Dome opens March 1, Whitney closes March 1. You can and should enter both. The Whitney application is only $6, the Half Dome application is $10, and together they cost $16 — less than one dinner out. If you win one, you either cancel the other (where refund rules allow) or gift the date to a hiking partner. If you win neither, you still have the Half Dome daily draw to fall back on all summer, and you can watch the April 22 Whitney release for a surprise.

Common mistakes to avoid: applying only for a single dream date in each draw (spread your requests across several days); forgetting the claim deadline after winning (unclaimed permits vanish back into the pool); and underestimating altitude on Whitney by driving up from sea level the morning of the hike. Acclimatize for at least two nights at 8,000+ feet before attempting the summit.

Frequently asked questions

Can I day-hike Mount Whitney without an overnight permit?

Yes, day-use permits exist within the same Whitney Zone quota (about 100 per day in season). They are part of the same February 1 – March 1 lottery and carry the same $15 recreation fee, so enter the day-use option on your application.

Do I still need a Half Dome permit if I am backpacking to Little Yosemite Valley?

Yes. A backcountry wilderness permit for Little Yosemite Valley does not automatically grant cable access; you need a separate Half Dome summit attachment permit, which is part of the same preseason and daily lottery system.

What if I win both lotteries for the same weekend?

Permit fees are partially refundable under each agency’s rules (typically with windows and penalties). The practical answer is to apply on different weekends if you can, or accept one and transfer the other to a partner where policy allows.
