What is a campsite cancellation alert?
A cancellation alert watches a campground's reservation calendar for your dates and texts or emails you when a matching site becomes available. We never hold or book inventory — you always finish the reservation on the official park website.
Openings can disappear in minutes and no alert service can guarantee a site, so keep your dates flexible and be ready to book when the email arrives.
Start free
- Text (SMS) and email alerts included.
- Up to three active alerts at a time.
- No card required for free beta access.
- Book directly with the park when an opening appears.
Need faster checks or more alerts? Paid options are planned for after the beta.
