How to actually get a campsite at Yosemite National Park

Every summer, thousands of people do everything right — logged in early, campground page open, finger on the button — and still watch Upper Pines sell out in front of them. It isn't you. There are two separate games for a Yosemite campsite, and the one everyone plays is the one with the worst odds.

Game one: the release

Yosemite reservations open five months ahead, in one-month blocks, on the 15th of each month at 7:00 am Pacific.

Yosemite's reservable campgrounds sell through recreation.gov, and they don't open all at once — each month-block goes on sale five months ahead. The park has adjusted its window boundaries before, so check recreation.gov's Yosemite pages for the current block dates before you plan around them.

If you want to play this game, play it properly: create your recreation.gov account ahead of time, know the exact campground and loop you want, have the page open and refreshed before 7:00, and book the moment the calendar goes green. Then know the honest part: for peak summer dates in the Valley, sites are gone within minutes, and you are racing everyone else with the same plan — plus some people running software. Showing up at 7:02 is already late. If you make it, wonderful. If you don't, you haven't lost. You've just moved to game two.

The campgrounds, briefly

• Upper Pines — The largest campground on the Yosemite Valley floor and the only one open year-round.
• Lower Pines — A small Valley-floor campground along the Merced River with Half Dome views, open roughly spring through fall.
• North Pines — The smallest of the three Pines campgrounds, tucked between the Merced River and Tenaya Creek near Mirror Lake.
• Camp 4 — The historic walk-in climbers' camp below Yosemite Falls — a National Register site and the birthplace of modern big-wall climbing.
• Wawona — On the South Fork Merced River near the Mariposa Grove of giant sequoias, at Yosemite's quieter south entrance.
• Tuolumne Meadows — Yosemite's high-country giant at 8,600 ft on Tioga Road, gateway to the Cathedral Range.
• Hodgdon Meadow — Just inside the Big Oak Flat entrance off Highway 120 — the closest campground for Bay Area arrivals and a frequent fallback when the Valley is full.
• Crane Flat — A summer campground at 6,200 ft near the Tuolumne and Merced sequoia groves, well placed between the Valley and the high country.

Game two: the cancellation

Here is the part the booking page doesn't tell you: a sold-out campground leaks sites back all season. On release day, people don't book the trip they'll take — they book every weekend they might take, because holding a site is cheap and getting one later feels impossible. Then real life arrives, and the extra weekends get trimmed.

The trims aren't random. They cluster in the last couple of weeks before an arrival date, as people on the fence finally bail, and they show up at odd hours — late evening is when “we're not actually going” becomes a click. Weeknights come back far more often than Saturdays, so if you can shape your trip around a Sunday–Thursday window, your odds jump.

recreation.gov's own availability notification exists, but it goes to everyone watching that campground at once, so by the time the email lands you're racing the whole list.

The watch-for-drops play

The catch is speed. A dropped peak-season site can be re-booked within minutes, because plenty of people — and plenty of software — are watching continuously. Checking the grid at lunch means the site that opened at 9:40 pm and vanished at 9:52 pm never existed as far as you're concerned.

By hand, the playbook is: check your exact dates (not the whole month grid) late at night, check daily starting about two weeks out, prefer weeknights, and have a fallback picked. That playbook genuinely works — it's how people got these sites for years. It's also a part-time job, and the moment you stop checking is always the moment a site opens.

The alternative is to let something else do the vigilance. A scout that checks your exact campground and dates continuously, around the clock, and emails you the moment a site opens — with the booking link, so you're clicking within a minute of the cancellation — wins this game for the least clever reason imaginable: it never blinks.

That's what Calafia does. Tell it the campground and dates in plain English — “email me if a site opens at Upper Pines for my dates” — and it starts checking, stays silent until something actually changes, and tells you honestly on the days it couldn't check. Watching one thing is free.

If you strike out

A few campgrounds in and around the park operate first-come, first-served seasonally, and the national forests outside the entrances hold more options — check the park's current camping page for the live list, because it changes by season. And weeknights in Wawona or Hodgdon Meadow are a real Yosemite trip. The Valley on a Saturday is the hardest version of this problem — every step away from that makes the game easier.
