Backcountry permit lotteries ration a fixed number of daily entries among far more applicants than trails can hold, using a randomized draw rather than first-come, first-served booking. Most systems open a multi-week application window months before the season, charge a small non-refundable entry fee, then notify winners weeks later — Yosemite's Half Dome preseason lottery, for example, runs March 1-31 for 225 daily permits, with results emailed in mid-April, according to the National Park Service (SRC-01).
The mechanics vary by agency, but the goal is the same everywhere: spread demand for a narrow, safety-limited resource — a cable route, a canyon corridor, a permit zone — across a season without collapsing the trail or the ranger station into a first-come stampede.
How does a preseason permit lottery work?
A preseason lottery opens a defined application window, collects a small non-refundable entry fee, and awards permits before the season the applicant is actually hiking. Half Dome's preseason lottery runs the entire month of March for hikes anywhere in the following cable season, and applicants can request up to six permits across specific dates or date ranges (SRC-01). The Enchantment Permit Area in Washington's Alpine Lakes Wilderness runs its advanced lottery annually in February, charges a $6 non-refundable application fee, and limits each visitor to one permit per season regardless of how many zones they apply for — a rule the U.S. Forest Service states plainly because demand "far exceeds the number available" (SRC-02).
Preseason systems typically let applicants name a backup: Half Dome allows one alternate per application, though a single person can only appear as a holder or alternate once across all of that applicant's preseason entries, which prevents one hiker from stacking odds through duplicate submissions (SRC-01).
How does a rolling monthly lottery differ from a preseason one?
A rolling monthly lottery repeats every month rather than once a year, with a short application window tied to a fixed number of months before the hiking date. Grand Canyon's noncommercial backcountry permit system opens on the 16th of each month for start dates five months out, closes at 5 p.m. Mountain time on the 1st of the following month, and posts results on the 2nd, according to the National Park Service (SRC-03).
The park then randomly re-orders every applicant in that cycle and gives the top 750 a specific login date and time slot — 8 a.m., 10 a.m., noon, 2 p.m., or 4 p.m. Mountain time — to log back into Recreation.gov and actually build an itinerary, rather than awarding a finished permit outright (SRC-03). The Park Service notes that most of those top 750 end up with some permit, but not necessarily the exact route or dates they wanted, since many backcountry sites hold only one group per night (SRC-03). Anyone outside the top 750 can still try for leftover space once general access opens later in the cycle, and the public can book any remaining nights once the following month begins (SRC-03).
What does a daily or walk-up lottery add on top?
A daily lottery reopens a short window close to the hiking date to reallocate permits nobody claimed. Half Dome runs one two days before every hiking date, open from midnight to 4 p.m. Pacific time, filled from estimated under-use and cancellations rather than a fixed allocation — and unlike the preseason draw, daily applications carry no alternate, just the permit holder (SRC-01). The Park Service also points out that daily odds run higher on weekdays, especially from late August on, when overall demand thins out (SRC-01).
What do these lotteries cost, and is any of it refundable?
Every system charges a small non-refundable fee just to enter, separate from the per-person camping or use fee charged only to winners.
| System | Entry fee | Per-person fee | Refund window |
|---|---|---|---|
| Half Dome preseason/daily lottery | $10 per application | $10 per person | Refundable if cancelled by 11:59 p.m. Pacific the day before (SRC-01) |
| Grand Canyon backcountry lottery | $10 (counts as the base permit charge for winners) | $15/night below the rim, $4/night above the rim, per person or stock animal | Nightly charges refundable up to 30 days before the trip start (SRC-03) |
| Enchantment Permit Area advanced lottery | $6 non-refundable application fee | $5 per person, per day, valid May 15-October 31 | Not specified for the recreation fee (SRC-02) |
Does applying earlier or more often improve your odds?
None of the three agencies describe a points system that rewards past losses or repeat entries — each cycle is treated as its own random draw. What actually widens your odds, based on the mechanics each agency publishes, is flexibility: Half Dome explicitly lists weekday dates from late August onward as higher-percentage picks in the daily lottery (SRC-01), and Grand Canyon's monthly cycle means a hiker open to any of several months gets several independent chances at the top-750 cut rather than one (SRC-03). Widening your date range or applying for a range instead of one fixed day works the same way in Half Dome's preseason form, which explicitly supports "specific dates or date ranges" per application (SRC-01).
What's the one habit that trips up first-time applicants?
Treating a lottery entry as a booking. A win in any of these systems is an invitation to claim a slot, pay the per-person fee, and in Grand Canyon's case log back in during an assigned window to actually build the itinerary — not a finished reservation. Miss the follow-up step or the payment deadline and the permit reopens to someone else, agency pages for all three systems make clear by tying the paid, person-level fee to a separate deadline from the lottery entry itself (SRC-01, SRC-02, SRC-03).
Conditions, fees, and lottery calendars change — check with the managing agency's Recreation.gov listing or ranger district before you apply.
