A surprising share of campsite reservations get cancelled. One cancellation-tracking service puts it near half. Each one goes straight back onto Recreation.gov, where whoever’s watching grabs it.
Recreation.gov’s built-in Availability Alerts (free)
They cover campgrounds, tours and timed-entry tickets: anything in current inventory.
How to set one up:
- Create a free Recreation.gov account (web or app).
- Open your campground.
- Tap “Set Availability Alert.”
- Pick a date, or a window of up to three days.
- Filter for what matters: tent-only, pet-friendly, RV length.
- Hit “Save Alert.”
When a site opens, you get a “Good News!” email or push. It even says roughly how many others got it, which is Recreation.gov’s polite way of saying run.
The limits:
- Three alerts per category (camping, tickets & tours, timed entry). Nine total, not ninety.
- Current inventory only. No alerts for dates that haven’t been released, and no warning about a future release.
- Everyone gets it at once. At popular campgrounds the site is gone in minutes. It’s a head start, not a reservation.
Third-party cancellation watchers
Same idea, more stamina: their computers refresh Recreation.gov so you don’t have to.
- You pick the campground, dates and kind of site.
- Their scanners check on a loop: every 1–2 minutes on paid tiers, 5–15 on free ones.
- A match triggers an email, text or push.
- You book it on Recreation.gov, which bans bots from completing purchases.
Some are free, some are paid, and at least one drops the site into your Recreation.gov cart. Different flavors, same race.
The honest part: it’s still a race
An alert often goes to many people at once. At Moraine Park on a July weekend, the site can vanish before your phone stops buzzing. Stack the deck:
- Stay logged in with payment saved. Every second typing is a second someone else is checking out.
- Watch a date range, not one sacred date. Flexibility is the biggest predictor of success.
- Know the pattern. In our Colorado monitoring, openings peak two days before arrival, mostly in the morning. No-shows free up Friday and Saturday nights.
- Turn on push notifications. Email works; a push you see in ten seconds works better.
The fees and deadlines behind that pattern: Recreation.gov cancellations, the rules and the timing.
Which should you use?
Start with Recreation.gov’s free alert. It takes two minutes. For a brutally competitive campground, or a whole range of dates, a third-party watcher earns its keep.
Either way, check conditions before you book. A site next to a fire closure or under smoke isn’t worth it.
Want someone else to do the watching? Set up a free watch and we’ll email you when a site opens at the Colorado campgrounds you want. Before any trip, check the free conditions board.
Common questions
Does Recreation.gov have free cancellation alerts?
Yes. Recreation.gov's built-in Availability Alerts are free and cover campgrounds, tours, and timed-entry tickets. Set one from the campground page with “Set Availability Alert,” and you get an email or app notification when a site opens up.
How many Recreation.gov availability alerts can you set?
Three per category — camping, tickets and tours, and timed-entry reservations — so nine total. Alerts only watch current inventory, so you cannot set one for dates that have not been released yet.
Do cancellation alert services book the campsite for you?
No. They notify you and you book on Recreation.gov yourself, because Recreation.gov prohibits automated bots from completing purchases.
When do campsite cancellations happen most?
In Campsite Ranger's monitoring of Colorado campgrounds, openings peak two days before the arrival date and come mostly in the morning, with a smaller evening bump. Watching a date range instead of one date is the biggest single boost to your odds.
