Creating Alerts
Which reservations can I create alerts for right now?
Search for a park or campground to see the areas you can monitor. Supported reservable day-use areas, including picnic areas and shelters, can also have alerts. Choose a visit date for day use, or arrival and departure dates for an overnight stay. The Coverage page shows our current reservation-system coverage.
Can I create an alert when an area is sold out or closed?
You can monitor sold-out dates when an area supports online reservations. Areas closed to online reservations are hidden from search. A hidden area can return once we verify that reservations have reopened and availability can be checked reliably.
How often are alerts checked?
Most active alerts start on about a 10-minute schedule. OpenCampsite may check high-demand parks sooner and quiet parks less often, and provider outages or processing load can also affect timing.
Why hasn't my alert found anything yet?
An alert fires when someone else cancels a reservation, and cancellations are unpredictable — many alerts catch an opening within days, others never do, especially for the most popular sites. We check around the clock either way. For the best odds: widen your date window, watch a whole campground rather than one specific site, and set alerts as early as you can.
