Yellowstone · Cancellation alerts
Yellowstone campsite alerts — for the right booking system.
Yellowstone splits its campgrounds between two reservation systems, and knowing which is which is half the battle. PingMyCamp watches the seven NPS-run campgrounds that book on Recreation.gov 24/7 and pings you within 1 minute when a cancellation opens a site that matches your dates.

Two booking systems. We watch one of them.
The NPS-run campgrounds — Mammoth, Norris, Indian Creek, Lewis Lake, Pebble Creek, Slough Creek, and Tower Fall — book on Recreation.gov. Those are the seven PingMyCamp watches, on a 1-minute scan loop, the same way we cover every other Recreation.gov park.
The five concessioner-run campgrounds — Madison, Bridge Bay, Canyon, Grant Village, and Fishing Bridge RV Park — book through Yellowstone National Park Lodges (Xanterra), a separate platform we do not monitor. If your trip depends on one of those five, we are not the right tool for that campground, and we would rather tell you now than after you sign up. The good news: the seven Recreation.gov campgrounds cover every corner of the park, from the North Entrance to the Lamar Valley to the road in from Grand Teton.
The seven campgrounds we watch.
Yellowstone releases these dates on a rolling window on Recreation.gov, and cancellations churn continuously after that — holds get trimmed, refund deadlines pass, plans change the day before. Any of the seven below can be an alert target.
North Entrance
Mammoth
Historically the park's year-round campground. Steady cancellation churn because it books across the widest date range.
Central — Norris Geyser Basin
Norris
The most central base in the park, within reach of both loops of the Grand Loop Road. Cancellations get grabbed fast.
Between Mammoth and Norris
Indian Creek
Smaller and quieter than the big names — a smart alert target when everything else reads sold out.
South Entrance
Lewis Lake
The natural pick if you are pairing Yellowstone with Grand Teton. Higher elevation means a shorter season, so dates are compressed.
Northeast — Lamar Valley
Pebble Creek
Small inventory near prime wildlife country. A cancellation alert is often the only realistic way in.
Lamar Valley
Slough Creek
Tiny campground in wolf-watching and fishing territory. Demand outstrips supply on almost every summer date.
Tower–Roosevelt junction
Tower Fall
Small and simple, close to the Tower Fall overlook. Summer weekends disappear quickly; weekday cancellations are the opening.
Yellowstone — common questions.
Why isn't Madison or Bridge Bay available on PingMyCamp?
Yellowstone splits its campgrounds between two booking systems. Madison, Bridge Bay, Canyon, Grant Village, and Fishing Bridge RV Park are run by the park concessioner and book through Yellowstone National Park Lodges (Xanterra) — a separate reservation platform we do not monitor. PingMyCamp watches the seven NPS-run campgrounds that book on Recreation.gov: Mammoth, Norris, Indian Creek, Lewis Lake, Pebble Creek, Slough Creek, and Tower Fall.
Which Yellowstone campgrounds does PingMyCamp watch?
The seven campgrounds bookable on Recreation.gov: Mammoth, Norris, Indian Creek, Lewis Lake, Pebble Creek, Slough Creek, and Tower Fall. If it appears on Recreation.gov, you can set an alert on it — same scan loop, same 1-minute notification speed as every other park we cover.
How fast do Yellowstone alerts arrive?
Within ~1 minute of a site opening. We scan Recreation.gov availability continuously, and Email + SMS fire the moment a campsite matching your alert shows up in inventory.
When do Yellowstone cancellations actually happen?
The same patterns as the rest of Recreation.gov: a wave shortly after popular dates open, when people trim multi-night holds; a cluster as refund deadlines approach before the trip; and day-before drops from changed plans. Cancellations churn continuously through the season — the problem is never supply, it is being first to see it.
Can I watch Yellowstone and other parks on one account?
Yes. Your 20 active alerts can mix any Recreation.gov campgrounds — Yellowstone, Yosemite, Glacier, anywhere — plus Parks Canada campgrounds on the same account, for the same $15/month or $45 lifetime.
Chasing more than one park?
Yellowstone alerts share the same account and the same 20-alert limit as everything else we watch — Yosemite's famously competitive release windows, Glacier's short season, sold-out campgrounds anywhere on Recreation.gov, and the entire Parks Canada network.
