Yosemite National Park · Cancellation alerts
Yosemite cancellation alerts for the campsites that sell out in minutes.
Upper Pines, Lower Pines, North Pines, Wawona — all bookable through Recreation.gov, and all gone almost the moment each reservation window opens. PingMyCamp watches the public availability 24/7 and pings you within 1 minute when a matching site comes back.

The 15th of the month, 7:00 AM Pacific.
Yosemite releases campsite reservations five months ahead, in one-month blocks, on the 15th of each month at 7:00 AM Pacific. The Valley campgrounds routinely sell out within minutes of that window opening. If you were not refreshing at 6:59 with fast fingers and good luck, the front door is closed for that month.
The back door is cancellations. Plans change constantly — people book speculatively at release, then trim nights or drop trips as the date approaches. Every change puts a site back into public inventory, usually for minutes, not hours. That is the exact problem cancellation alerts exist to solve: we watch Recreation.gov continuously and notify you the moment your dates reappear. It is the same approach we use for any sold-out campground, tuned to a park where speed matters more than almost anywhere else.
Yosemite campgrounds in coverage.
Anything reservable on Recreation.gov is watchable on PingMyCamp. The list below covers the campgrounds most people are chasing — handy starting points if you are not sure where to set an alert.
Yosemite Valley
Upper Pines
The Valley's biggest reservable campground and the default target for most trips — which is exactly why it vanishes first.
Yosemite Valley
Lower Pines
Smaller and seasonal, along the Merced River, with the same walk-everywhere Valley access as Upper Pines.
Yosemite Valley
North Pines
The smallest of the three Pines. Tight inventory means a single cancellation is often the only way in.
South of the Valley
Wawona
Near the park's south entrance and Mariposa Grove — a solid base when the Valley loops are gone.
Big Oak Flat entrance
Hodgdon Meadow
Just inside the west entrance at lower elevation; a practical fallback that suits tents and smaller rigs.
West of the Valley
Crane Flat
Sits near the junction toward Tioga Road, positioned for both Valley days and high-country days.
High country
Tuolumne Meadows
High-elevation camping on Tioga Road with a short summer season. Whenever inventory is listed on Recreation.gov, alerts work the same way.
Yosemite Valley
Camp 4
The historic climbers' camp runs its own reservation process; alerts apply to whatever reservable inventory appears on Recreation.gov.
Not just Yosemite.
The same 20 alerts cover every campground on the two platforms we watch. If your summer plans also run through Yellowstone or Glacier, those campgrounds sit on rolling Recreation.gov release windows with the same cancellation dynamics. And if the trip crosses the border, Parks Canada coverage works from the same account.
Yosemite alerts — common questions.
Does PingMyCamp work with Recreation.gov for Yosemite?
Yes. Yosemite's reservable campgrounds are booked through Recreation.gov, one of the two platforms we watch alongside Parks Canada — same scan loop, same alerts, same pricing.
How fast do Yosemite alerts arrive?
Within ~1 minute of a site opening. Email and SMS fire the moment a matching campsite shows up in inventory — which matters in Yosemite, where returned sites are often rebooked in minutes.
When do Yosemite cancellations cluster?
Two windows: shortly after each monthly release, when people trim speculative multi-night holds, and again in the days before the trip as refund deadlines pass. Day-before drops are also common.
Does it cover Camp 4 and the high-country campgrounds?
Alerts cover reservable inventory listed on Recreation.gov. Camp 4 has its own reservation process, so coverage applies to whatever reservable inventory it lists there. High-country campgrounds like Tuolumne Meadows are seasonal — when they are bookable on Recreation.gov, alerts work identically.
Can I use one account for other parks too?
Yes. Your 20 active alerts can mix Yosemite with Yellowstone, Glacier, Parks Canada or any other campground on the two platforms we watch.
