Most campgrounds unlock one day at a time. Yosemite unlocks a whole month in a single morning — the 15th, at 7:00 a.m. Pacific, five months ahead — and the good nights are gone before your coffee cools. Here is the full year of release mornings, mapped.

If you learn one date in American camping, learn the 15th. Yosemite runs the most regimented release calendar on Recreation.gov: no daily trickle, no rolling window for its valley floor. Instead, the campgrounds strung along the Merced River — Upper Pines, Lower Pines, North Pines, plus Wawona and Hodgdon Meadow — release their inventory in monthly blocks, on the 15th, at 7:00 a.m. Pacific, five months ahead of arrival. One morning decides a month of Yosemite nights, and that morning is a contact sport.
Each release covers a one-month arrival block. Read the table the way a regular does: find your trip first, then read left to the morning you have to win.

The February and March 15ths are the Super Bowls: they carry the June, July, and August blocks, when school is out, the waterfalls are still running (June) or the high country is open (July–August), and every family in California has the same idea in the same minute. The November and December 15ths, carrying spring blocks, are measurably calmer — and spring in the Valley, with the falls at full power, is the connoisseur's trade.

By 6:45 a.m. PT: logged in (sessions expire — log in fresh), payment saved, party size and equipment length set. Open the exact campground page, not the park page: in Yosemite's block release, navigation time is inventory lost. Know your order of battle: first-choice campground and dates, second choice, third — written down, because the interface will not wait while you deliberate, and a site you hesitate over is a site in someone else's cart. At 7:00: select and complete checkout well inside the ~15-minute cart hold. At 7:15: the first abandoned carts begin recycling — the same flicker window the Washington Monument hunters know. Keep checking until about 7:45 before you call it. After a total miss: you are now in the cancellation market, which for Yosemite runs all season — the subject of how campsite cancellations actually work, and the market our cancellation index measures nightly. In the live log's first nights, Upper Pines alone produced more confirmed openings than any other campground we scan — released at 7:03 to the fastest clickers in California, and returned, quietly, by ordinary people whose plans changed.
Upper Pines is the biggest (235 sites in the official directory) and the most fought over; it is also, for the same reason, the richest cancellation market — the largest inventory produces the largest absolute number of drops. North and Lower Pines are smaller and closer to the river's bend; Wawona sits near the south entrance, an hour from the Valley floor, and trades the iconic commute for a measurably calmer release morning; Hodgdon Meadow, near the Big Oak Flat entrance, is the regulars' pressure valve. Every one of them is in our sold-out guides with its directory facts and its alternatives mapped. The strategic point generalizes: in a block-release system, the second-best campground in the same release is not a consolation prize — it is a separate, softer market opening at the same minute.
Five months ahead of a mid-month release produces a persistent off-by-one error: campers aiming at a July 4th weekend compute "book in February" and arrive on February 15 ready for battle — correct — but campers aiming at, say, July 20 compute the same February and miss that their date sits in the next block (July 15 – August 14), released March 15. The blocks are anchored to the 15th, not to calendar months. Circle the block your first night falls in; the release that matters is that block's, and multi-week trips spanning a block boundary are won in two separate mornings. It is the single most common Yosemite booking error we encounter, and it costs nothing to avoid — the table above is the whole fix.

The Valley block release is the 15th. Tuolumne Meadows uses the 15th too, two months out for half its sites. Crane Flat and similar smaller campgrounds use two-week rolling windows. Individual listings always govern — check the exact campground's Recreation.gov description.
Peak blocks (June–August) can clear their best sites in minutes. The full month doesn't vanish instantly — shoulder dates and less-famous campgrounds linger — but a Saturday in July should be treated as a seconds-long event.
No. Between the 15-minute cart recycle on release morning and cancellations all season, Valley inventory returns constantly. Upper Pines is the most productive cancellation market in our live log.
No — nobody legitimately can. We watch the official calendar every 2.5 minutes and text you when a matching site opens; you book it yourself, in your own account. See the methodology page.
