Yosemite is the hardest campground reservation in the country — Valley sites can disappear within minutes of release. But bookings churn constantly: sites are cancelled and re-released every single day of the season. The campers who land one late aren't lucky, they're just watching at the right moments. Here's how the system works, and the fallback that actually gets people in.
Yosemite's campgrounds book through recreation.gov — but not on the usual rolling 6-month window. Reservations have traditionally opened in one-month blocks, five months ahead, on the 15th of the month at 7:00 AM Pacific (so a July trip opens on February 15). Peak-season Valley dates are routinely gone within minutes. The park has adjusted its release calendar in recent years, so confirm the current schedule on each campground's recreation.gov page before your release day — and be logged in, with your dates and payment details ready, before 7:00 sharp.
In the Valley itself: Upper Pines (the biggest), Lower Pines, North Pines and the walk-in Camp 4. Outside the Valley the odds improve: Wawona near the south entrance, Hodgdon Meadow and Crane Flat off Big Oak Flat Road, Bridalveil Creek up Glacier Point Road, and the high-country set along Tioga Road — Tamarack Flat, White Wolf, Yosemite Creek, Porcupine Flat and Tuolumne Meadows. A Tioga Road site plus a day of driving beats no site at all — and the high country is spectacular in its own right.
Every sold-out Yosemite campground leaks sites back constantly — plans change, and each cancellation goes straight back on sale at a random moment. The surges follow the usual pattern: a wave around 10–14 days before check-in as the cancellation-fee deadline bites, and another 2–3 days out. Refreshing recreation.gov by hand almost never wins; put the campgrounds you want on a free CampSage cancellation alert and check the live map for 🔥 just-opened sites. Our cancellation timing guide covers the pattern in detail.
Camp 4 — the historic climbers' campground under El Capitan — doesn't use the standard five-month release. In peak season access runs through a daily lottery on recreation.gov, entered one day before your arrival; in the off-season it reverts to first-come, first-served. It's a genuine option for a spontaneous Valley trip when everything else is gone — see our first-come, first-served guide for how to play walk-up camping generally.
National forest campgrounds ring Yosemite on every side — often half as contested, some first-come, first-served, and many within a short drive of an entrance station. Browse campgrounds near Yosemite with live availability, or turn the trip into a loop with the Yosemite & High Sierra road-trip itinerary. Holding a booked backup outside the park while an alert watches your first-choice campground inside it is the strategy that most reliably ends in a tent under Half Dome.
Traditionally in one-month blocks five months ahead, released on the 15th of the month at 7:00 AM Pacific via recreation.gov. The park has tweaked the calendar in recent years, so confirm the current release schedule on recreation.gov before your target date.
Watch for cancellations — sold-out Yosemite campgrounds release sites back every day, especially 10–14 days and 2–3 days before check-in. A free real-time alert beats manually refreshing recreation.gov.
In peak season it's tough: most campgrounds require one, and Camp 4 runs a daily lottery. Off-season, some campgrounds go first-come, first-served. Year-round, national forest camping just outside the park is the reliable no-reservation fallback.
The Valley campgrounds (Upper, Lower and North Pines) are the most contested. Odds improve at Wawona, Hodgdon Meadow and Crane Flat, and improve again at the Tioga Road high-country campgrounds like White Wolf and Porcupine Flat.
