Planning a camping trip to a popular national park in 2026? If you show up without a permit, you'll likely be turned away. The most sought-after backcountry and campground permits for Yosemite, Zion, Grand Canyon, Glacier, and Mt Whitney sell out months in advance — sometimes within minutes of release. This guide covers exactly how the permit systems work, when to apply, and how to improve your odds.
Recreation.gov is the centralized permit platform for most federal lands, including national parks, national forests, and BLM areas. You need a free account (create it now if you don't have one: recreation.gov). Permits for different parks release on different schedules — there's no single "permit day."
Key Recreation.gov tips:
| Park/Area | Permit System | Application Window | Success Rate | Walk-up Available? |
|---|---|---|---|---|
| Yosemite (Half Dome) | Preseason lottery | March 1-31 (2026) | ~20-30% | Yes — daily lottery 2 days prior |
| Yosemite (Wilderness) | Lottery + first-come | 24 weeks in advance, rolling | ~35-50% (varies by trailhead) | 40% of permits held for walk-up (7 days prior) |
| Zion (Angels Landing) | Seasonal lottery | Jan 1-20; April 1-20; July 1-20; Oct 1-20 (2026) | ~15-25% | Day-before lottery via Recreation.gov |
| Zion (Wilderness) | Online reservation | 2 months in advance, 10am MT | ~40-60% (The Narrows fills fastest) | Limited; don't count on it |
| Grand Canyon (Corridor) | Early access lottery | 4 months in advance, 1st-15th of month | ~25-40% | Very limited cancellations |
| Grand Canyon (Primitive) | Fax/email application | 4 months in advance (first of month) | ~50%+ (less competitive) | Yes, South Rim Backcountry Office |
| Glacier (Wilderness) | Early access lottery | March 15, 2026 (8am MT); general on April 15 | ~60% overall, but ~15% for popular routes | Yes, same-day at ranger stations |
| Mt Whitney (Day Use) | Lottery | Feb 1 - March 1, 2026 | ~10-15% | Cancellations posted online |
| Mt Whitney (Overnight) | Lottery | Feb 1 - March 1, 2026 | ~25-35% | No-show permits released at 2pm day prior |
Half Dome cables are up from roughly late May through mid-October (snow-dependent). The preseason lottery runs March 1-31 in 2026 for the entire season — you apply for a specific date and will know by mid-April. A daily lottery (2 days prior) gives you a second chance.
Wilderness permits (required for all Yosemite backcountry camping) operate on a rolling 24-week window with 40% of each trailhead quota held for walk-up release 7 days before the entry date. The Lyell Canyon (JMT northbound) and Happy Isles (JMT southbound) trailheads are the hardest to get — John Muir Trail hikers compete for these and they vanish within minutes of release.
Angels Landing now requires a seasonal lottery permit (started in 2022 due to overcrowding and safety incidents). You must have a permit even for a day hike. The lottery windows for 2026 are quarterly: January, April, July, and October, each covering the following 3-month period. A day-before lottery on Recreation.gov provides a fallback.
Zion backcountry permits (The Narrows top-down, West Rim, Subway) release 2 months in advance at 10am Mountain Time. The Narrows top-down route (16 miles, permit required) may be the single hardest backcountry permit in the park system to obtain — prepare backup plans.
The Grand Canyon uses different systems for corridor trails (Bright Angel, South Kaibab, North Kaibab) versus primitive/remote routes. Corridor permits go through an early access lottery 4 months in advance (apply the 1st-15th of the month before your trip). Primitive zone permits are processed by fax and email applications, with a more manual (and slightly higher-success) process.
The Phantom Ranch lottery (overnight lodging at the bottom of the canyon) is separate, has a ~5% success rate, and requires its own entry 15 months in advance.
Glacier National Park's wilderness permit early access lottery opens March 15, 2026 at 8am Mountain Time. You submit up to 4 itinerary choices. Lottery results come out by early April. Unclaimed permits release to general reservation on April 15.
Glacier is one of the few parks that still holds a significant number of permits for walk-up distribution — about 30% of backcountry sites are reserved for same-day or next-day walk-up at ranger stations. Show up at Apgar or St. Mary at 5am for best odds.
The Mt Whitney Trail (both day use and overnight) has the lowest success rate of any major backcountry permit in the contiguous US. Roughly 60,000 applications chase about 6,000 permits annually. The lottery runs February 1 through March 1, 2026, with results released mid-March. You can apply as a group of up to 15, but the entire group must be accepted or rejected together — larger groups have worse odds per person.
If you fail the lottery, check Recreation.gov daily for cancellations (especially April-May as lottery winners finalize plans). A small number of no-show permits are released at 2pm the day before each entry date at the Eastern Sierra Interagency Visitor Center in Lone Pine.
Permit stress is real, but it's also manageable with preparation. Set calendar reminders for application windows, have backup plans, and remember that some of the best camping experiences are in less-famous national forest land that requires no permit at all. Check our campsite selection guide for what to look for once you secure a spot.
